Hey Zx? Can you tell we love ya?
Only our ignorance of higher coding prevents us from doing more. (speaking for myself at least).

Yes that's it. :)

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?

The sound part take 20% of the total CPU, so may be the ME should be able to do a bit more than the sound ... i have to test :)

Hey ZX does less stress on the CPU mean more speed?

If you want any help with some basic coding zx-81, I am willing to help you.
I would like to become more familiar with coding for the psp as I have some ideas of my own. :)

This way two birds are struck with one stone.

Yes, i'm working hard to integrate the ME. I could have release something this week (without ME) with some new features and new skin, but i would have been flamed immediatly by all kids, because it's not faster than previous version ;) ...

Thanks, but for the moment i needn't, may be later if someone want to rewrite the UI ;) (even if i won't change mine).

Don't worry i've read all suggestions / feature requests. Some of them are already done (such as zip support), but i will soon sum up all requests, and discuss each one to see if it is possible or not. But from now, nobody cares about new features, we all want more speed ;)

yes more speed thats the most important right now. Oh and thanks for every thing ZX

I should come soon, because i've sucessfully rewritten the sound part of the emulator, and it's now running with ME :D ... But problems still remain to pause the sound etc ... (communction between the main CPU and the second core is not so easy ... mainly due to the memory cache ... ). But i can say now, that the emulator is running at the same speed as previous version without the sound (so 100% for several games), but now the sound is played by ME !

I will probably put back the real ARM stick computation, it's slower but emulation is more realistic (less lag).

thats great news ZX, thanks for all your hard work, that couldnt have been easy:D :D

just curious, but have you tried implementing other tasks to the ME to see if that helps the speed as well?

I wonder if sound playback is better or even perfect now !?

Nice to hear it and I hope you have the audio frequency configurable, for 11khz, 22khz and maybe 44khz(for future ventures). :D

Haha good work.:cool:

Also isnt the second core your refering to just the GPU? Also this hardware specification might be helpful, at this url - http://wiki.ps2dev.org/start.

I refer to the second MIPS R4000 (in the Media engine) :)

We don't care about sound frequency, when you can always run it at 44Khz, and not altering the global performances ;) ...

Sound playback is not good for the moment ... I've to rewrite some part to have a better synchro between the ME and the audio samples player thread.

hey Zx, i saw that you said if you released another version kids would flame you cuz the speed is the same, but seriously, dont worry about them, if they can't apreciate your hard work then they dont deserve anything.

Great work Zx, your by far one of my fav. PSP coders on here.

Thanks, I'm just sick of all these kids crying cuz the speed is slow. If you go see the comments on pspupdates.qj, its full of kids complaining.

Awesome work

:D This knew GBA emulator is awesome it is by far the best on PSP i have come across so far. The menu interface is easy to work with + there is increased smoothness in the gameplay ive got my tales of phantasia running at 50%+ with sound on :D. I just know with all the hard work you are putting in this is going to be the best gba emulator for PSP.

Lol, I overlooked that detail of the media engine :D
and nice work on the integration.

:rolleyes: Also could we get a pre-release version plsss, if you still have alot to do before the next release.

Keep up the good work, and many thanks.

Can't wait for the release. And you really shouldn't listen to what noobs are talking about speed in comments.

Besides DevHook this is the project I keep looking at. A GameBoy Avance Emulator makes the PSP perfect for me. :) Please keep it up ZX, you can do it!!!
