Is there a game boy advanced emu for the pocket pc if so what is a link to some where i can download it from? and what other emulators are there for the pocket pc??<br>-chris

I think that the GBA emu's for the PC are not working at a fast enough level to be that playable on the PPC. I think the best a port could do right now is at the level of the SNES emu's give or take. But someone could try if they haven't already. I heard though that on a P2, the game runs at 21% of the actual game speed, and then getting a GBA bios that works is difficult. The ARM on the GBA is supposedly 16MHz but raw speed doesn't convert straight over into the PPC since the GBA is not concerned with processing anything other than the game itself. <br><br>

Emulating a 16Mhz ARM on a 206Mhz StrongARM *should* be a piece of cake. Only thing you have to do is add code for the hardware stuff. If you can do that in arm asm, an emu should easily be fast enough on the iPaq, and it should look better than the original... With the backlight, I mean.<br><br>Point is, a PC GBA emu can't do this, so we can't port a GBA emu (like everyone is doing with all the other emu's). We would have to write one from scratch, and that takes an aweful lot of technical knowledge. Emu coders are some of the most talented coders in the world, I believe.

do it phantom;)

I wonder what ARM version the GBA uses.

[Telorus Overmind]

I found a GBA emulator that uses Java and one that runs on Linux. Maybe they can be mcguyvered somehow to run on a Java/Linux enabled Ipaq?<br><br>*Must..have..Advanced..Wars..Frustration...Building*

i read this morning that the gb emu guy has almost done a gba module for it. its on pocketgamer.

As far as I know.. the GBA uses the ARM processor in Thumb-mode.. that means 16bit mode.<br>The ARM in the ipaq is running in native ARM mode (32 bit).

[Moose or Chuck]

pocket gb will be releasing a emu for it that hits 15-20 fps soon. I can live with that

[Sparky009]

Ugh, the GBA's running in thumb?<br><br>Damn...<br><br>hypothetically, though, shouldn't it still be a direct transfer? I mean, can't the arm arcitecture simply handle both types of asm natively?

[jongjungbu]

I thought both were 32-bit and supported Thumb-mode for 16-bit instructions.

Since the GBA has an onboard Z80 for GameBoy compatibility, could your GBA game use it along with the ARM?  Parallel processing on dissimilar CPUs.  Oh man, that would be a nasty to debug.<br>

[Sparky009]

actually, with pocketgb emulating the Z80, and assuming the direct asm GBA plugin starts to work, it might not be so bad...<br><br>but I do believe the z80 and arm on the gba are in seperate hardware spheres... that is, the trigger in the cart slot itself turns on and off the arm chip in hardware... at least, I think so... someone correct me if I'm wrong.
