Zx-81, who's been hailed as QJ's resident emulator porting machine (a much deserved title, we might add), is back with the latest update of his PSPVBA GBA emulator - PSPVBA v1.2.0 (Media Engine). In this newest version of PSPVBA, Zx-81 gives us these new features to expect:
  • All the sound part has been rewritten to use the media engine so it's faster
  • Graphical Unit access was improved
  • Added new beautiful icons and background (designed by Win-Win)
  • Added option to enable/disable GBA battery/flash save to avoid disk save every 10 seconds in several games
If you haven't tried PSPVBA, here's how you install it:
  • Unzip the zip file, and copy the content of the directory FW1.5 on the PSP/Game directory.
  • Put the ROM image files on "ROM" sub-directory.
See that doesn't sound too hard. The complete instruction is listed in the readme file in case you have some issues. And now for the bad news: PSPVBA v1.2.0 doesn't work for +2.0 FW. Sorry 'bout that. But Zx-81 has included one binary version for 1.5 FW and the source codes in the download file. You can post your comments, suggestions and praises for Zx-81 at the comments or in our forum's release thread.

Update 1: zx-81, showcasing his Barry Allen-like skills, just updated this emulator to fix the analog/digital swap bug minutes after the other one was released earlier. The link below has the updated file.



Update 2: Third time's the charm! zx-81 has wasted no time in releasing the next version of this emulator with the following fixes and changes:
  • New feature to save and load a distinct setting file for each games
  • Add option to enable/disable the cache with the Graphical Unit
  • Emulator menus reorganisation (new menu for settings)
  • Bug fix: Emulator menu is now launched on startup
  • Bug fix: no more freeze when exiting the emulator (but HOME button still doesn't work !)
  • Bug fix: bad refresh of the emulator menu/screen

 » why even be fw2.**

you people suck, why complain that it doesn't work on fw2.** ? unless you're actually on 2.71 (in which case you upgraded for some idiotic reason) . just downgrade and you can use devhoook, it works perfectly.

finding gba roms is quite easy, just google it, or find places which do the gba emulators or whatever...

Most games are still too slow to be playable and from the looks of it, it won't get any quicker.

My advice, if you want to play gba games, buy a gba or even a DS. Full speed with sound. Amazing.

 » Question?

Any roms that play at a workable speed?

my completely random testing is showing 6-8fps, with garbled sound for most things ;)

 » FPS

OK, I loaded "Golden Sun 2" ROM, emulator reports 7-8 fps with "Skip Frame"=1 and 10 fps with "Frame Skip"=0, sound was enabled, all other settings - default, except "Show FPS" of course :) Again, good job Zx-81, keep it up!

   by stee (Unregistered) - 2006-07-23
 » great

I tried the first golden sun rom running it with sound, no frame skip and my results were a locked 10fps

the sound is still horrible but was a improvement over the last version

here are some screenshots ;

ZX-81 deserves great thanks for even starting this emulator. Hopefully it will soon be as complete if not more complete than the snes emulator. Imagine playing all those sweet gba roms like megaman battle networks and advance wars (1000x better than field commander), castlevanias and others. Keep up the good work Zx-81, we need to see this emulator at full speed and sound.

 » Thanks ZX

ZX - thanks for the continued work on this project - I would rather have small updates twice a week than one major update every other month...thank you. If you read these, could you explaine why (using small words so I'll be sure to understand) it is so difficult to get this emu running when SEGA, SNES and NEOGEO-CD are near, if not, perfect? You are a great and dedicated coder, do you have any future plans to work on a MAME project?

   by zx-81 - 2006-07-23

@all: thx

@23: 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 ;) ...

Zx.

 » Thanks for all your work but ...

Will we ever see 30-40 fps with good sound?

   by zx-81 - 2006-07-23
 » @25

sorry, but i don't think so ...

   by eggwonder - 2006-07-23
 » omg!

i got pokemon fire red running at 64%(30 fps)! this is amazing! if i turn off the sound it goes up to 70%(30fps)

zx-81 you are amazing keep working on this so we can have at least one emu that emulates good games.

btw as soon as i get home and get my screenshot i will show my proof of 30 fps.

i believe u. i had pokemon sapphire run at 75% (30fps} with sound on it wos very choppy but it wos ok. thanks again Zx-81 4 ur hard work.

   by Oily (Unregistered) - 2006-07-23
 » thanks but no

I know some people who are too poor to buy $20 GBA games will like this work, and since they can't afford stuff they don't care that games run slow. You know what those cheap dirtbags say, slow is better than nothing.

But good job zx-81, you made some people very happy. :)

 » Hmmmm

Until it gets to 100% I'll be sticking with my 512 MB
X-Rom and GBA SP/DS Lite. But progress is progress. I'm still confused on why so many PSP owners want to play Nintendo GBA games on their systems.

No amount of emulation can beat playing it on the real thing.

I was wondering how sony can get ps1 games to run at full speed on the psp

do they just create an emulator for specifically for one game so they can tweak it for that games needs

this seems the harder but more sucessful way as i read someone was making ott on the psp work using this method

OMFG Another heap of ***** its slow i mean make a slow ... Il stick with Mario or the snes
