Hey ZX

i was just thinking.......would it be possible to emulate the ARM7 on the media engine? like for example, the main cpu would emulate the sound and and everthing else while the media engine would emulate the ARM7....would that be possible?

Of course it's possible, but all the emulator has to be rewritten, and performance would be worse

... (due to cache problem).

Does PSPVBA use the GBA bios if it's available?

If so where should it be placed and what is the proper file name for the BIOS itself?

Also, any workarounds to get the NES Classic series working? (other then using NesterJ to run the real NES version :P )

This one just gets better!

Zx, Are the arm ticks in the pspvba the same as the sound clock ticks in vba?

the arm tick in pspvba is the average number of ticks for each executed ARM instructions.

Normally, in the initial source code of VBA, there is a complex computation of the real ticks (depending of the instruction that is executed, the type of memory etc ...). But i've removed this stuff and put the average value instead. This improve the speed, but it's less realistic than the original emulator.

ZX you rule. Now for mi ?? Is there a way to implement the addtions of your counter parts emulator to your future releases

Could you put in some options to run the sound with different settings pls, as I feel 22khz would be fine, and sacrifices have to be made in certain areas in order to bring emulation requirements down to work with the 333mhz processor rather than needing a 400mhz one.

Note: Havent people been reporting that they had better sound on ver 1.1.0 which only ran at 22Khz.
