www.ngemu.com look at theyre forums theyre all about pc emulation. they'll have all ur answeres.

Any progress on the Media Engine?

yea im wondering that too, this is been the longest wait for a next release compared to the others, although im very patient and by no means should he need to rush. but um..he's on either brake or major improvements or SOMTHING. with Zx you never know...or do you?

ya i know hey, im already excited for the next release. hey zx do u think you can give us a little update on how things are going?

Well, i've tried many things to improve the speed but without any success from now. As an example, i've rewritten the ARM processor emulator function to improve the decode step, but it doesn't provide any befenits . So i went back to the original code.

I've also remove the SDL stuff for the audio part, to use directly the audiolib functions (first step needed to integrate the Media engine process). I've added a new menu to choose the sound quality (best quality is more cpu consumming of course).

I've begun to integrate the media engine stuff ... but many work still remain, and this won't increase the speed. This emu will go as fast as it already goes without sound ... so don't dream about a full speed GBA emu .

See your working hard ZX. We apreciate all your eforts.

That doesn't mean it won't yield benefits down the road. If it does indeed improve the decode step, (regardless of the expected result not manifesting), could it not have other benefits you don't yet see? or am I not understanding correctly?

If I'm not mistaken, using the media engine will take some pressure off the CPU, right? So this may provide better, cleaner sound at speeds already realized? If so, that in of itself is a major accomplishment.

Logically, I would have to agree. Also, in user mode you only use the main cpu, right? does Kernal mode provide access to those other 2 processors?

Hi zx-81, and nice work.

Do you have vsync set somewhere in the code for pspvba, and what filters are you using on the screen output- if any(because Virtualboy uses multiple filters to increase picture quality which increase the load on the processor).

Also I wonder if using the gba bios function in Virtualboy for the pspvba would increase performance. I have a bios file if you need it.

Keep up the good work, chat to you later.

hey ZX, i have a question

would it possible after the sound is fully emulated on the ME, to put some other operations on the ME as well?

the whole point to my idea is to equally stress both the media engine and the CPU.

or would sound alone stress the ME enough?
