SubjectDoes any computer have enough CPU power for Mame yet? new Reply to this message

Posted on04/09/08 10:09 AM



With all this new CPUs, quad cores and all the overclocking and I don't know if the ones with 8 cores are out yet but does anyone know if any CPU out there has the balls to run all Mame games full speed?

I do have a Dual Core 2.4Ghz at 3.2Ghz and well last time I tried some games, they still ran at 25fps I think. I'm considering upgrading my PC since I can add Ram so cheap right now and I can even add another 8800 GTX for about $275 since someone is selling one for that and I was wondering about proccessor upgrades as well and wether any CPU out there can run all mMme games full speed or close to full speed with sound.

But I suppose there's still not enough power to run the more insanely power hungry games out there. And i also don't think MAME is capable of utilizing a quadcore CPU to it's full extent.

All work and no play makes me..., well, you know the rest.

True, there is no processor out there that runs all MAME games full speed.

MAME can optimally use 2 cores in more recent versions. Anything more (4, 8) will not yield substantially better results. You're better off sticking with 2 cores and faster speeds (I.E. 2 Cores at 3.0Ghz as oppose to 4 cores (or more) at 2.4Ghz).

Furthermore, MAME posts fastest/best performance under 64-Bit OS and 64-bit MAME compile.

That's sad that old crappy games can use so much CPU power when emulated. Is it againts the Mame licence to modify it to add speed hacks or optimize the code to gain performance over accuracy?

Cause personally I would give a rat's ass how perfect the emulation is if a game is not playable. I would rather have some speed hacks in place or use video processing power to render certain things and speed up emulation and it suprises me that Mame being a open source project and no one has really taken the time or effort to try to speed up some of these games.

I agree with you but sadly, MAME is more about accuracy than game playability. Very rarely will MAME include speed hacks. I wish MAME would change its policy because once upon a time, there were many arcade emulators and you could use an alternate. Nowadays, active arcade emulators are far a few between. It seems that the arcade world is limited to MAME and thus held hostage to the MAME policy.

Abandon all hope of ever seeing games like Gauntlet Legends (along with many others) run at full speed using an arcade emulator.

No, it isn't against the license. The license is pretty much "do what you want as long as you give back the source and don't make money out of it".

I'm not surprised. Writing fast emulators is hard, speed hacks tend to be one game only, and the reward, unending abuse by whiners who want more more more, is not worth it.

There is a decent discussion along these lines at MAMEWorld. In respects to Gauntlet Legends or any Arcade Game unable to be played at current system specs "Pi" made a good point here:

http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=148624&page=0&view=expanded&sb=5&o=&fpart=1&vc=1

Specifically:

"...I remember when people were angry because Mortal Kombat was crawling on their systems, and asked for faster emulation, regardless of accuracy. However, nowadays we have systems good enough to run them. When the DCS sound system used in the MK series was emulated, again they were crawling again; again the current computers can handle it pretty well. If no one cared about correctly emulating MK then, now we would have MK emulation without real DCS, with glitches, and without anyone knowing how to correctly emulate that except by starting from scratch again.

That's why mamedevs are against patches, hacks, kludges, or any emulation shortcuts which might damage accuracy. You end doing the work not once, but twice or more. Mamedevs try to do it once, but doing it well".

Anyhow, the whole thread is actually pretty good reading.

We aren't stopping you from spending all your free time writing a better emulator. Or you could come round to my house and mow my lawn and clean my car, then I might be more willing to do what you want.

Seriously, why do the MAME DEVs feel compelled to get offended when someone simply states facts? I find it hard to believe that ALL MAME DEVs feel the need to come out swinging as you did here. Did I bash MAME in any way? No. In fact, I love MAME and use it quite frequently.

You could offer a reply for discussion but your reply here is typical of most MAME DEVs that get offended at the drop of a hat.
