Sega 32x Emulation

[Trashman]

I think iignotus thinks that there are two 200Mhz CPUs with a combined performance of 400Mhz, he's wrong.

​

In which way aren't they?

Are you sure two 200mhz processors together produce 400mhz?
My understanding of it is it just gives you two lots of 200mhz to play with, like having dual processors in your pc, good for multi-tasking but dosent give you any speed increase.

On the note about there being no good games, I highly enjoyed Star Wars Arcade, but other than that, it's pretty much useless. I think onbly 30 games were ever released for it, and most of them were ill-conceived and had many bugs.

On the other hand, I would love to see a Sega CD emulator for the GP2X, just so I can play Sonic CD.

​

Ditto, also Knuckles Chaotix and SwagMan. Actually, I don't know if SwagMan was ever released, but I remember seeing the previews and it looked fun.
Sonic CD, Ecco CD, Wonderdog, Keio's Flying Squadron, Willy Beamish... These MegaCD games were fun. Probably.

In what way is multi-tasking NOT a speed increase in productivity??? It's not like emulators and games or linux only do one thing at one time. Computers have been able to multitask since the 80's....

1) Isn't the XBOX 800MHz x86 if I remember right? GP2X will always be 200MHz. Never enough to do 32X, not even with dynamic recompilers.

2) Sega/Mega CD also is VERY unlikely. If I remember correctly, there are two (or more) extra chips, including one Z80. Anyway, the Z80 is a hell slow to emulate alone, add to that the other extra chips(s) and the original Genesis emulator... (yes you need to emulate a full Genesis PLUS a Mega CD. duh.)

Please dont compare Mhz. The 86x is a CISC chip (sorta) and the ARM a RISC chip.

Also x86 usually has good floating point performance, MMX/SSE/3Dnow!, and strong support hardware.

The ARM has no floating point AT ALL. No MMX or other stuff.

Its like comparing a Supercharged Fuel-Injected V8 to a Lawnmower engine. They do different things for different reasons, and work VERY differently.

ALSO The 32X Has what; 4 Processors... SH2 *2, 68K, Z80. Throw in a SegaCD with its own 68K and you have a whole heap of CPUs to emulate. I think the 32X+Genesis+CD combo has the most CPUs of any video game system ever. I'm not saying it won't ever happen... its just not likely. Also Z80's are pretty simple processors, emulation of them is easy.

Yes they are super simple =)

May i add there were well over 90 mega-cd games or sega-cd as any of you americans call it

Anyone got that Brazilian version of duke-nukem 3d for the genesis? lol

 

[Mark1970]

Would a form of high level emulation make it more possible?
Look at N64 emulation, this is only feasable on today's PC/Mac because of high level emulation.
Cheers, Mark

Have any current emulators made use of both of the GP2x CPU's in parallel?

 

[mattyrb]

Another old topic dug up There was a Jaguar emulator that supposedly made use of it....whatever happened to that?

 

[god_at_hell]

No, but they have slowed down light... for quantum computers =)

OffTopic:
[smartass-mode]
They reduced the phase-speed of light ... not the group-speed. The group-speed is allways ~2.9979*10^8 m/s

[lintsniffer]

I would be happy to help any coder interested in such a project.

Beer, sandwich, now.

I'm afraid I've been massively overwhelmed by paying work, and haven't had the time to finish it and release a build (or even really follow the goings on in the GP2X community... )

Don't worry, I haven't lost interest in the emulator or the GP2X! I have been doing little bits and bobs to the GP2X version of the emulator in my scant spare time, and hopefully in a few weeks the pressure should slacken a lot and I'll be able to finish it.

The emulator's original author has expressed an interest in radically improving the efficiency of the sound emulation code too, and that would obviously filter down into the GP2X build. I think he's a busy chap at the moment as well, though...

Sorry for the delay, hopefully this project will be underway again soon.

I'd like to know an answer to this as well.. because I'm always hearing about how difficult it is so I'm assume nobody has done it :unsure: ??
