haha, yea, or "the Super Best Devs"

(mean while, back at the super best devs..., Zx has finished a fully working GBA emu with speed and sound, and a N64 and PSone emu have been finished)

do u think it will ever be possible to get the emulator to work at least nearly as good as a real gba?

LMAO... Or the.... Super Homebrewing Machines!!!...
( The super homebrewing machines have ported the ps2and it is running at full speed with decent sound, Perfect sound is promised in 10 seconds, the next release

well Zx has stated a few times before that he's nearing the end of the GBA emu's limits. simply becouse (from what i heard) GBA needs 400 mhz..psp-333 or somthing close along those lines.

some clear it up for me cuz im half awake here.

From the prior release's thread....

GBA -> 32-bit 16.8-MHz ARM
NeoGeo -> 16 bits 12 MHz 68000
Snes -> 16-bits 4 MHz

The PSP is max 333Mhz.

Generally to emulate properly a processor you need multiply the frequency by 25, and it gives you the required frequency for the host processor. Here, 12 * 25 > 300 Mhz, so we can emulate a SNES or NeoGeo.

But for GBA : 16 * 25 > 400 Mhz, so we can see that it will be theoretically very hard to emulate a 32 bits / 16 Mhz ARM processor on a PSP ...

So it will be hard but "nearly" might be possible.....

........so is it basicly like putting a quarter in a straw??

Damn

another release in the same day. Hats off and bow for zx please.

Isnt the GE handling all the GFX, maybe the code for that area needs to be looked at again, or maybe PSPGL can be used?

Also since the program has been ported from the PC, could there be max volume setting or something simple like that causing the cracks and pops.
It keeps reminding me of when speakers are pushed to the end and over their frequency range. ( They start to under perform and the music becomes distorted)

I can play Golden Sun well when it comes to graphics, only that it hisses and seems to slow the rest of the system down inorder to syncrhonize the sound to the graphics during battle scenes.

I feel it could be this is because the game slows down alot when the battle scenes appear, with loads of action( coupled with the graphics slowing to the sound effects speed), but when im just in exploring mode and the sound is not as intricate, the game plays much better.

Even though the fps may be shown around the same, it cound still mean their being held back to sychronize.

-So maybe the sychronization coding can be optimized.
-Maybe there can just be sound compensation settings which dictate whether to speed up the sound to match the graphics.

- Pls check to see if the speakers are actually being pushed too far by your settings.

Lol my longest post so far.
