Overclocking Your Sega Genesis/MegaDrive

Deven "Epicenter" Gallo writes "I've recently been working on a project to alleviate the slowdown inherent in older game systems. How you ask? By overclocking them! I've managed to perfect overclocking the Sega Genesis / MegaDrive. The processor (a Motorola 68000, running at a stock speed of 7.6 MHz) can be pushed to 16.0 MHz in my experience, and I am still working on higher. The machine doesn't overheat and is entirely stable at these higher speeds."

That may be justification alone for why the systems were underclocked at the factory. The clock in many games is based not on an actual clock but the speed of the processor... speed things up and you speed everything in the game up, and that's not very playable.

Unless somebody's found a way to get this thing to run Linux and other non-cartrige programs, this isn't going to be very useful.

Err, you might be right about programmer's being relatively lazyish (/efficient) and relying on the processor speed for timing...but they could always easily slow down a game that was too fast, but not the opposite.

Actually...programers don't JUST use the processor speed, or else slowdown would never happen, there wouldn't be a "correct" pacing for a game, just a continuum...few objects -> fast game, some objects -> medium game, many objects -> slow game. Instead, a game has a 'desired' speed, and probably just burns cycles if it's done everything but it's not time to proceed. If there's too much happening, the gmae slows down, and no cycles are burned.

The underclocking was probably due to the tolerances of the manufacturing process at that point. At this lower clockrate, virtually every chip is usable, at this higher rate, more can't keep up.

Monkelectric (546685) | more than 10 years ago | (#8529318)

i'd be surprised if even sega games were so poorly programmed that they depended on the hardware clock speed. Generally what one does is define a unit of time (actual time, clock ticks, cycles, etc -- doesn't matter as long as its uniform), then you define all the motion/game logic as functions of a time delta (time elapsed between the last frame and this current one), since the frame rate is never constant. This way, things happen at a constant rate regardless of frame rate.

That being said, ive never done any console programming, so who knows :)

You're right. Even on newer consoles, like the Xbox, a 1.4 ghz cpu and 128 mb ram [gamestron.com] upgrade tends to have problems in certain games. Most console games, unlike their PC counterparts, run proportional to the CPU clock for actual game speed.

In a PC, overclocking the CPU will usually increase frame rate in newer games. Consoles, with their unified architecture, begin to run into compatibility problems when you make certain components run faster, or will usually speed up gameplay proportionally to the clock speed increase.

Yes, the above applies to the PC-like xbox too, but not to every game. From what I've been told, running Halo co-op splitscreen on that 1.4ghz xbox runs as smooth as silk.

LucidityZero (602202) | more than 10 years ago | (#8529165)

Most (if not all) of them, I'd assume.

When you're developing a game for a specific platform that will never change, why would developers use any sort of time-based algorithm to determine game speed? You'd end up with a smoother/prettier game if you merely used the limits of the hardware to control the speed of your game.

Especially back in those days where most of the games really DID push the limits of the hardware. Almost any game would slow down with too many sprites on the screen, etc.

I'd assume almost any Genesis game would play very, very quickly on an overclocked system.

Re:Most of them... (3, Informative)

LocalH (28506) | more than 10 years ago | (#8529285)

If the game just updates the screen whenever the hell it feels like it, busywaiting until it's time, then yeah, it'll fuck up. But any properly coded game will utilize the VINT to synch to the refresh rate. Sonic 2 does this for sure, you can even see the garbage in the bottom border where the game is initializing the VDP for the next frame.

Re:Most of them... (1)

Kris_J (10111) | more than 10 years ago | (#8529325)

Most of them are timed based on the video signal. Depending on how well they were coded, they may will run at normal speed, just with fewer dropped frames when the sprites pile up.

Re:And this is good? (5, Interesting)

... James ... (33917) | more than 10 years ago | (#8529198)

You'd think it would be most, but that doesn't appear to be the case:

I've written my own Nintendo Emulator. Just modified it to execute 5000 CPU instructions per scanline instead of the typical 114. Fired up Super Mario Brothers, Contra, and a few other games and they all appear to work fine.

I suspect (and I would've thought otherwise before this test) that many games are sychronized with the v blank interval or interrupts. I haven't tested sound, however, since I haven't written that part of the emulator yet.

Re:And this is good? (1)

... James ... (33917) | more than 10 years ago | (#8529240)

oh yeah, and I know that NES != Genesis, but for the purposes of this discussion, it's probably safe to assume that similar techniques would've been used when developing for either platform.

Re:And this is good? (3, Informative)

Pr0xY (526811) | more than 10 years ago | (#8529268)

I've also mad a NES emualtor before, and there is a reason the games arent running any faster.

firstly, many of the games wait for an event (such as the vblank to occur), or sit in an infinite loop waiting for an NMI to process the next frames work.

Firstly, as you probably know, NES games tend to be very timming critical. Switch to a game that does any cycle counting to determine with things should happen (just about anything made by RaRE should do) and it'll be all fscked up :)

And as for the speed itself, you aren't executing the instructions any faster, just waiting till more work is done before showing rendering the scanline. This is not the same as the effect of overclocking would have on a real thing. The real with would still execute 113.66667 (or whatever the cycle count it) CPU cycles per scanline...just faster.

LordK3nn3th (715352) | more than 10 years ago | (#8529073)

If you can overclock it so much with a noticeable performance, then why didn't Sega set it like that already, if it's so stable? Certainly it would have given them an edge...

Pushing a 7.6 --> 16MHz is over 100% more than the original! I have yet to see most people get anywhere near that on normal processors.

Re:Hmmm.. (1)

Bull999999 (652264) | more than 10 years ago | (#8529104)

Not if they are unclocked to begin with. Those processors ran at 16MHz on Macs without any problems.

LordK3nn3th (715352) | more than 10 years ago | (#8529130)

That's the point. The article apparently claims that it remained stable at over an additional 100%. Now, not all processors are alike, but if one of those can handle up to that, shouldn't others be able to handle a fairly good amount of overclocking as well?

Well you've got to remember that these things were made for several years. Just a guess, but I'm thinking by the time the last ones they sold were made, Motorola probably had long since quit making 7.6mghz chips, and were just shipping whatever their bottom of the line was at the moment and underclocking it.

Also, you have to remember even if that's not the case, there's a lot of variability in chips. Just because this guy got his to run at this speed reliably, doesn't mean they all would.

Re:Hmmm.. (2, Interesting)

LordK3nn3th (715352) | more than 10 years ago | (#8529199)

Yes, it's very possible they were underclocked for compatibility reasons. But I doubt they would've gotten a freak chip that could handle so much... I'm sure if that one could get so high, others could get high too (maybe not as high, but still high).

Re:Hmmm.. (2, Insightful)

IntergalacticWalrus (720648) | more than 10 years ago | (#8529225)

"The article apparently claims that it remained stable at over an additional 100%"

Yes, but for how long? Sega wanted their machines to run a few years tops. Overclocking your Genesis CPU and still having it running after a week barely proves that Sega has underpowered it.

Re:Hmmm.. (5, Interesting)

BW_Nuprin (633386) | more than 10 years ago | (#8529136)

Its possible that later production Gennys had better processors that were clocked down to maintain the same speed as the older models. In the five or so years that Genny was around, I'd expect that there were many many improvements to the 68000. I'd wager that the last couple Gennys off the line could be overclocked three or four times over without a sweat.

Re:Hmmm.. (1)

calica (195939) | more than 10 years ago | (#8529204)

Very true. I overclocked the 68000 in my Amiga 500. Reliability was a major problem. Ended up using an ice cube in a ziplock. Not very sustainable but fun (hey I was 12). I'm sure the later Genesis had underclocked CPUs. At the time 68030 and 040s where current in PCs.

Re:Hmmm.. (1)

LostCluster (625375) | more than 10 years ago | (#8529200)

Because games were depending on the clock speed to be equal on all of the consoles, for any clocks within the game or other time-based things. What likely happened was during the life of the console, the original chip got discontinued so later units just underclocked the successor chip to be close enough.

Re:Hmmm.. (1)

Orcish_Rodent (665783) | more than 10 years ago | (#8529214)

First it wasn't the first generation units he is working with see this from his instructions:
It should read 'MC68000', 'MC68HC000', 'HD68HC000', et cetera. If it reads 'SCN68000', the system can most likely not be overclocked.
And Because it wasn't fully stable at higher speeds. See his results page:
7.6 MHz - 100% Stable. Stock speed.
12.0 MHz - 100% Stable, 80% of lag removed.
13.4 MHz - Must be switched into after boot in most cases. 98% of lag removed. Minor music/sound issues, Sonic 2 Special Stage shows severe graphical glitches. Otherwise fine.
14.7 MHz - Must be switched into after boot. No lag. No glitches except Sonic 2 Special Stage.
16.0 MHz - Must be switched into after boot. No lag. No glitches except Sonic 2 Special Stage.

Re:Hmmm.. (1)

Epicenter713 (761169) | more than 10 years ago | (#8529233)

The SCN68000 was a 'budget clone' used in very early Revision 1, Model 1 MegaDrive/Genesis machines. I've not had it put up with anything. At 13.4 MHz it becomes convinced I am trying to run a US game on an EU system, then locks up. When I'm not. ;D

Re:Hmmm.. (0)

Anonymous Coward | more than 10 years ago | (#8529229)

When I popped open my original Genesis (bought in the days of the Altered Beast package), I seem to remember the chip being rated as a -11(?) or -14. It was also someone else's fabbing of the 68000, though memory is hazy.

So it's been entirely possible that Sega designed around Motorola parts and reference materials, then found a second-source supplier who gave them a better deal in bulk on chips that exceeded their specifications.

Plus, from this site [digitpress.com] , looks like they designed around the 7.6MHz rate for other things (bus to the Z80 for music-generation, and so on).

This probably applies more to the NES then anything but... I never understood why developers would release games that had obvious slow down problems in the first place. I mean if they did any kind of testing they should have noticed them. Another thing I don't under stand is why didn't emulator authors ever consider upping the speed or the emulated processor to fix these type of things? I am not much of a programmer but could anyone maybe explain this to me.

Re:hrm (2, Informative)

BW_Nuprin (633386) | more than 10 years ago | (#8529078)

I don't recall exactly, but I think you could 'overclock' the genesis in older emulators like Genecyst, so perhaps that would be a good way to check to see how well games run overclocked before you actually futz with your real Genny. I would think that many games would have timing problems at a speed greater than stock, particularly those that use raster effects. I can't say for certain, but I know my old Gameboy Color raster effects would break completely if I overclocked them. I would wager that racing games would probably suffer the worst.

Kinda seems pointless... (1, Funny)

Moocowsia (589092) | more than 10 years ago | (#8529080)

Afterall TVs dont do much more than 30Hz and most games were made to run at about 30 FPS without the overclock. Essentially any improvements won't be noticible.

WRONG, WRONG, WRONG, WRONG, ALL WRONG (2, Interesting)

LocalH (28506) | more than 10 years ago | (#8529275)

NTSC does 60Hz, PAL does 50Hz. Most games update the screen every frame, a few will do it on two's. This actually has a use with all games that are programmed correctly, especially those which rely on raw CPU time.

It'd also be nice to play around with in a C64-styled demo, banging on the VDP with the increased cycles available at the higher clock speed. I wonder what happens when you try to hit the VDP too fast. To compare, with a SCPU-equipped C64, the 65816 simply blocks until the 1MHz bus frees up, if it needs to.

The Java of the Mars (-1, Offtopic)

FUDOH The New Genera (757303) | more than 10 years ago | (#8529093)

OK So there is like an advertisement up there and it is all FIND OUT AT THE SUN ON THE MARS or something. And it's like Java on Mars or something like that. And I'm like, WTF. Is this like that movie? The Passion of the Christ? Why do they call it that anyway. I mean, isn't the name Christ. Shouldn't it be, the Passion of Christ. But no. It's the Passion of the Christ. Directed by the Mel Gibson, starring the Jesus. You don't fuck with the Jesus!!!! Quintana man. Fucking six year olds. But you know, that movie would have been sweet if there was like Artie Lange announcing the title. "The PASSION of the CHRIST!!!!" Artie Lange is a god. He should have played god in the movie. Also, The Monica Bellucci should have shown her breasts. You know, for the artistic value and all.

I mean, first of all I was all confused because there is the Sun on Mars. I think Sun is like a company, I'm not sure. So I guess the company can be on Mars. But it's somewhat vague. Is the actual Sun on Mars? I hope not, that's kind of scary. T_T If that was the case, then the Mars would be the Sun. Then the Java is on the Mars, which is maybe also the Sun. So I guess the Java is getting hot because it is on the Sun, and the Sun is hot. But the Mars is cold. So is the Java going to cool down? I don't know. I think if we model the Java as following the standard relation from thermodynamics Q = mc(delta-t), where c is the specific heat, we can determine that due to the relative difference in mass between the Mars and the Sun, the Java will experience a net increase in heat, which explains its evaporation lines in its associated graphic.

But I don't know. I tend to wonder why they would associate an interpreted high-level language like Java with the low-level systems programming associated with unmanned space travel. That's kind of silly. I mean Java doesn't even have like pointers or whatever. Pointers are kind of like the female breasts you know. Whenever you can like reference memory by address, it's like, you know you are alive. Kind of like when you're holding a nice, firm, supple pair of breasts. It all kind of comes together. Sometimes I think I like the hot weather because then like the ladies wear the more revealing clothing. But then sometimes I think I like the cold weather because then like the nipples are standing at attention. But Java doesn't let you play with her breasts. She keeps them buried beneath several layers of plain, dull colored sweaters. And really, her breasts aren't even all that nice to begin with. But then like C or ASM. She just takes those nice ones out at any opportunity, and you can play with them all you want.

You know what else. Like, you can't do any manual memory management either. You can't delete, you have to wait for the Garbage Collection to clean it up. You know, I can pick up after myself miss. If I wanted a maid I'd hire one. C doesn't care, she just is like, whatever, wanna fuck? Then DeNiro shoots her in the parking lot. C and ASM are like, the single life. You can like, have sex, and feel her up, and like, have sex. Java is like being married or whatever. She's always nagging you, forcing you to define classes for everything and like catch exceptions and go to your daughter's piano recital and then like buy some flooring from the hardware store for the new kitchen cabinets. Everything has to be a class. Everything has to be difficult. It's endless.

One time I was wondering like, what if a girl had like an endless pussy? Would she always be unsatisfied? Because on one hand, no guy could ever reach her cul de sac. But on the other hand, she never could experience that feeling anyway. There is no such physical object as an infinite dildo. That would be a good name for a band. Infinite Dildo. Anyway what if you were like, you know, sexing her up. Slowly running your fingertips through her hair, along her smooth face. Caressing her supple breasts. Data travelling around through memory. Remaining penetant at her altar, licking her pussy thoroughly, gently tickling her with the tip of your tongue, then wetting her down with long, loving strokes. She quivers softly, her pussy expanding, dilating. I take her clitoris in my lips, kissing it, letting it know, that it is loved. Her head back, her pussy opens, calling to me, a gentle feminine voice, "Come in me, come in me".

I slowly push my face into her pussy. I feel myself coming out the other side. Reaching up, pulling the labia aside, my arm outstretched into her pussy, I slowly climb through, the air pleasantly warm. I feel myself completely engulfed by the pussy, my feet falling onto the damp floor, an arid environment amongst a misty haze. In the vagina there is an old bunny rabbit. He says, Welcome my son, you have entered the void. There is no escape from here. You have attained Nirvana. And I was like, Cool. Then he was like, you have change for a twenty? But I only had two fives. He was all pissed or whatever. Well, what was I going to do.

Anyway. C is like the slutty white girl with nice DSLs and the heart of gold. You know, she just wants to make you happy. Java is all like the married housewife with the vagina dentata. You know, it can't even work on its own. It needs an interpreter to run its own compiled bytecode. Kind of like the housewife needing the husband to go do the work. Typical. C or ASM at least compiles to machine code and whatnot. It may not be LL(1) but, that's cool. She still has a nice rack. I think that's really like, what's most important or whatever. A girl can have a great personality, but if her breasts are all fugly, it's all over babe. I need some pointers to manipulate.

I'll be overclocking my analog clock. It'll be stable since the hands will do a full sweep in 1 minute without them disintegrating and flying apart.

as to how high his cute little hit counter registers before his server reaches critical mass? maybe he should've turbocharged that machine first...

It's a shame he didn't overclock his server to twice it's original speed. Those 10-25MB .avi's really don't help.

I overclocked my calculator, which also happens to use a motorola 68K, turns out that it ran just fine with a definite improvement in speed, and no noticable errors. And it made playing video games in class so much nicer;)

the genesis / mega drive ALREADY has blast processing, why the hell would you want / need anything faster!

Plug it into the 220 outlet behind the stove. It'll run really fast for a couple of seconds and then you can get on with your life.

How does it work with other genesis attachments? (4, Interesting)

Recovery1 (217499) | more than 10 years ago | (#8529219)

Now here's an interesting thought. What would happen if you hooked one of these overclocked Genesis into the Sega CD or 32X attachments? As I recall the whole process of getting the Genesis and Sega CD to work together in parallel was a challenge to begin with because of different clock speeds between the two CPUs in each device.

My guess is he hasn't tried it or it doesn't work, as he doesn't elaborate on it.

Re:How does it work with other genesis attachments (2, Informative)

Epicenter713 (761169) | more than 10 years ago | (#8529245)

It works great .. only thing is, DO NOT boot the Sega/Mega CD over 12 MHz or it will get panicky. The best method is to boot at 7.6, run the game. Then once at the title screen halt and go to the higher speed. The 32x works great in my experience as it doesn't rely on the 68000 much .. it uses a pair of its own SH-2 chips.

Sega slowdown... (5, Informative)

Anubis333 (103791) | more than 10 years ago | (#8529226)

Slowdown is an integral part of older consoles. Modern day emulators that can easily push these consoles with no slowdown at 60FPS impliment a technique to fake "slowdown." It's a lot easier to just grab a genesis emulator for your Dreamcast [dcemulation.com] or Xbox [xbox-emulation.co.uk] than attempt a hardware mod like this.

Re:Sega slowdown... (3, Funny)

LocalH (28506) | more than 10 years ago | (#8529295)

WTF? You're trying to say that the NES' horrible OAM cycling is INTENTIONAL and is a valued part of the experience? You're on crack.

3D Graphics on a TI-85 (2, Interesting)

KalvinB (205500) | more than 10 years ago | (#8529235)

While in High School I was always coding various things in BASIC on it and one day when I demonstrating how to map 3D objects by placing the sonic sensor on an overhead cart and rolling it under light fixtures, this kid in my calc class goes "you expect that thing to act like a Pentium." I used TI-BASIC to learn how to do 2D translation and rotation and touched on some 3D. I made the first and possibly only graphical adventure game for it complete with text entry and a cursor to click on objects.

A few years ago I gave it to a friend who needed a TI but I'm pretty sure the Intel Inside Pentium MMX sticker is still on the back of it.

Yeah... I rmemeber 12 years ago... (1, Interesting)

Anonymous Coward | more than 10 years ago | (#8529249)

I was tinkering with this on my Amiga 2000 almost the same exact hack... a switch that let you choose between the standard 7MHz and 14Mhz tapped from elsewhere on the mobo. It worked well once I finally sourced a 16MHz 68000 instead of the stock 8MHz. Cheap and dirt simple hack... helped out with DigiPaint rendering among other things, but then again... on a console... why?

SavannahLion (701337) | more than 10 years ago | (#8529252)

I've had a cached URL [vuni.ne.jp] to overclocking your Genesis/Mega Drive for a long time. Unfortunately, it's in Japanese and Babel Fish makes it really tough to understand technical instructions.

I wonder if the author of the article at Epic Gaming read the Japanese article and got the idea from there?

Re:Great, it's in English... (1)

Epicenter713 (761169) | more than 10 years ago | (#8529265)

Nah, I was working on it before I found that, actually. He swapped the CPU and the RAM, among other parts .. if you change components, it's not really 'overclocking'. He went and bought a faster 68000 to install. I'd rather see how far the real deal will go. :)

We did have a few martyrs in the process of producing a working machine. But they died from other causes, not the actual overclocking.

I wish someone would show me how to do this on the nintendo 64. Perfect dark was one of my altime favorite games...but it is truely unplayable in some situations. For example if you play the cooperative mode... the frame rate is absolutely terrible.

i remembered having massive slowdowns in streetfighter - especially if you're using guile and execute any combo more than 4 hits

my favorite combo... but lags in SNES...
jumping fierce + close fierce uppercut + sonic boom + referse fierce + sonic boom.

ironically this was under SF2 TURBO

I'm not going to let those Sega fanboys get the upper hand on this. They already taunted us SNES owners about their "blast processing" in the early 90s.
