Overclocking your Gameboy Advance

An anonymous reader writes "The guys over at Ahead Games are working on an overclock mod for the GBA. They've been able to run it at up to 2x the regular operating speed without any major heat or battery life problems. Now, you're probably asking yourself "Why the hell would anyone want to overclock their Gameboy?" Answer: Super Nintendo emulation. There's already a working beta of a SNES emulator out for the GBA called SNES Advance. The big problem is there's just not enough horsepower under the GBA's hood to emulate the SNES sound chip. This mod will hopefully remedy that."

The GBA is a 32 bit 16MHz RISC core, the SNES is two 16 bit processors, one of which tops out around 3.5MHz and the other of which (the graphics chip) I dunno about, plus a slow little 8 bit sound chip. However, using a RISC processor to emulate three CISC chips is not going to be easy.

      "The W65816 (also: 65C816), a 16-bit microprocessor developed by the Western Design Center (WDC), is an expanded and compatible successor to the venerable 6502. The 65816 has two 16-bit index registers, a stack pointer, a 16-bit direct page register, and a 24-bit address bus." (http://www.nationmaster.com/encyclopedia/WDC-65C8 16)

      That's four registers right there. The sound processor probably has more (but certainly has smaller) registers. The video processor, I have no idea about. Nonetheless the speeds of your processors put together are more than half the speed of your CPU, the total number of registers in the system probably exceeds the number of registers in the GBA CPU, the assorted CPUs run at different speeds so for perfect emulation you are going to have to play some neat little tricks that become more and more irrelevant as you get more processing power, but which are very significant at the levels we're talking about.

      In short, there's not much CPU in there to emulate a SNES at full speed. Hell, the snes emulator on the dreamcast has trouble with some of the more complicated snes games for some reason :)

    I have the gameboy advance player for Gamecube, and I wonder if this would work on that? It has more than enough buttons, and it shouldn't need overclocking.

    hey don't make squat on the GBA

    I wasn't aware they were taking a loss on the system, but I still don't think that this would cause them to LOSE money. It would encourage GBA purchases, and once some one has a GBA they are a lot more likely to buy GBA games than when they didn't have a GBA.

    I originally bought my GBA to play games that were ported from the SNES, but I really like some of the games that were developed for the GBA directly. They are pretty cool, and I wouldn't have even tried them if it weren't for the SNES games that drew me to the GBA in the first place.

    1) Not true. *Some* of the best SNES games are available on the GBA. Not all of them, and not even most of the big-name ones. Squaresoft's older games are notably absent, for instance, except for the remake of Final Fantasy Adventure. Terranigma and the other SoulBlader games, my absolute favourite action/RPGs, are also absent. So is Nintendo's Super Metroid, or many others. This mod would also be good for running PC-Engine/TurbografX-16 games, some of which can't currently run at fullspeed and essentially none of which are available on the GBA.

    2) The overclocking can be turned on and off at will, even while running games. ;b You would have known that if you had read the article.

  38. Just need to use dynamic translation by pslam · · Score: 5, Informative
    I hate to be pessimistic, but full speed SNES with sound support probably won't happen on the GBA anytime soon, even with overclocking. My PDA, which has a 400MHz Intel Xscale processor overclocked to 472MHz can only run maybe 5 or 6 SNES games with low quality sound at full speed, everything else skips. Without sound, almost every game will play full speed.

    That sounds like a really slow emulator. It's probably an interpreting one, which means you can expect it to be something like a 100-1000 times slower than the emulated system clock-for-clock. A good example is Bochs, which is pretty damn slow, but the interpreted approach allows it to run on many systems with little porting.

    What you really need for a fast emulator is dynamic translation - rewrite snippets of emulated instructions into native ones, and run that instead. You can get close to a 1:1 ratio of native:emulated clocks, which means in your case you'd have a 472MHz XScale emulating as if it were a 472MHZ SNES.

    There's plenty of examples of dynamic translators about. Transmeta's processors all run a dynamic translator from x86 to some freaky native instruction set (they call it "code morphing"). Java's JIT (just-in-time) is an example of a very similar thing - it translates byte code to native instructions on the fly, but doesn't have to worry about maintaining the virtual system's state, because Java doesn't have the concept of one.

    So yes, it should be possible.

  39. Street Fighter would actually be pretty easy by Syncdata · · Score: 2, Interesting

    Just assign the L and R as modifiers, so that A by itself is light punch, L+A=Medium punch, R+A= Hard punch.
    Is it going to play the same? No. Is it still playable? Yes.

      what about games that require multiple buttons at once then? like in super metroid... L and R are for look, and then you have your run, jump, shoot, and what was the last button? wasnt that moon walking? wich is also useful. and start/select are also needed to go to menu, and switch switch weapons. *SOME* games will work, but not ALL. it really made me sad to find out the GBA was lacking two buttons when they made it tho... i'm hoping the DS has a more SNES style configuration.

    Adding a shift button would effectively take us from six buttons to ten: (6-1) x 2

    Still...what about games where you need quick access to all of the buttons? Fighters, Street Fighter II being the big one, would be nigh impossible to play, as would any games that require the use of multiple buttons in quick succession.

    I still think that SNES emulation on the GBA is a lost cause...Wait until the next system, possibly the DS, and get it right then. Don't bother when you don't have enough buttons OR horsepower.

  41. Chess, Super Mario Kart and other classic games... by Jagasian · · Score: 4, Insightful

    I still play Super Mario Kart battle mode for the SNES, on a regular basis, with my friends. The games are short, action packed, full of strategy, and lots of fun. So you can squeeze in a few games every now and then with your friends. Super Mario Kart is over 10 years old!

    Another perfect example is Chess. It is hundreds of years old, and people still play it today as they find it entertaining to do so. Board games can be seen as the precessor to video games. They are visual games that require manual human intervention to enforce the rules and update the board layout.

    In fact, it could be argued that some games get better with time. When Chess was first invented, everyone was equivalent to how you and your friends were when you first tried to play it: they all sucked. Games were won basically by luck in the begining. As time went on, what people knew about Chess and how to play it improved. So the games of Chess that were played when it was first made are not nearly as good as some of the games played hundreds of years later.

    I notice the same thing with many of the video games that I play for more than a year: Tetris, Quake, Super Mario Kart, etc... my enjoyment of them has increased over the years because my knowledge of the games has improved.

    For multiplayer videos games, my skills as well as the skills of my opponents have improved. Hence our matches are more entertaining than the early years, when matches were won mostly by luck of a player stumbling onto on aspect of the game that had yet to be discovered.

  42. Other overclocking reasons by Psykechan · · Score: 3, Insightful

    Overclocking gaming systems is not new. I overclocked my Atari Lynx back in the day.(24MHz from 16MHz)

    The reason I did it was to play games in turbo speed. STUN Runner played great at 1.5 times speed. A 1.2 to 1.4 increase would be great for most GBA games. Underclocking could also be useful for poor gamers. I know a lot of gamers who would like a speed switch on their system.
