There allready is one. :)

It doesn't work for me... It just crashes to the menu.

Anhaedra: As I told you already. Emulation is slow as shit. Lets do the following calculation: If you use a REALLY good N64 Emulator on a PC and most Games should run (Zelda), you need 750 or for some games 1500 or even more MHz. The console itself has a 64-Bit MIPS R4300i RISC CPU with 93,75 MHz, so you need 8 to 15 times the power you want to emulate. Now lets check, what results of it:

200/8=25 MHz
200/15=13,3 MHz
266/8=33,25 MHz
266/15=17,73 MHz
300/8=37,5 MHz
300/15=20 MHz

13,3 - 37,5 MHz how nice.

If you look @ QEMU's Page you'll see that they tlak about a Factor 5 - 10. This gives following results:

200/5=40 MHz
200/10=20 MHz
266/5=53,2 MHz
266/10=26,6 MHz
300/5=60 MHz
300/10=30 MHz

Sounds better, but refers to IDEAL values. I think the MAXIMUM Spped you could get on a 266 MHz clocked GP2X is 45 MHz with QEMU and 30 on BOCHS.

Ok then how did the N64 emulator Corn manage full speed on Pentium 200mhz machines with 3D accelerators? And I'd say that 30-45mhz X86 emulation on a handheld is damn good.

Corn uses a static recompiler = The Emulator is made around the game. Some guy (in this case ContraSF) looks how a game runs and what it does next etc... and optimizes a program to do this very fast. Thats why it does not run much games. And no, this cant be done in Windows 95 and QEMU
 
OFFER: The one who can build the newest QEmu for the community (and for me) will get 15€ (~20$) from me. I'll send per PayPal. I invite People to follow me and send money,too. This is the only way to get X86 Stuff a bit faster than with DosBox and Bochs.
