Yoshi's Island GBA

[Exophase]

Read my sig.

[HAMMIEZ]

i tried it on gpsp 0.9 and it freezes on the opening cinematic - i think something is meant to fall into the screen and it doesnt. Although the rom isnt frozen because the music etc. continues to play and the yoshies continue to jump about.

stick with snestyl0.42me as it plays perfecto.

it does? because my fps is always bad and the sound doesnt play after loading state (yes i have fiddled with the options and i know what im doing)

well i think Y I is unplayable on snestyl0.42me. u need at least 3 frameskip to get it work at a decent speed.. and it looks so damn ugly then :P

it works perfect on gpsp 0.9, although there are some slowdowns in the castles, but thats ok for me

Thanks for that (and obviously for the emu in general) Exophase, I'm off to hunt down another bios to try.


EDIT:
From the readme: "As far as I'm aware there are two BIOSes floating around, I doubt you'll get one that isn't one of those two. There's a very easy way to determine which one you have - just look at the very first byte in a hex editor. The correct BIOS begins with 0x18, the buggy BIOS begins with 0x14"

Guess what mine began with. I really should pay more attention to these things, the search continues


EDIT2: Found, working beautifully. It runs FAR better than the snes version under snes9xPSP.
Thanks again Exophase.

Could you check your inbox please?

how can we tell which are the good bios and which are the bad. if we dont dump them

The real one will be 16,384KB

*If you want a good one Download VBA emulator *THE PC ONE* And find the file gba.rom Its there Bios rename it to gba_bios.bin then youre all set.

the VBA download only comes with NEWS, README, COPYING, and VisualBoyAdvance, no gba.rom!

[grantlionheart]

o.o then where the hell did this bios come from... i sure as hell didnt download it...

[bah]

grantlionheart: The buggy bios is also that size in KB, I just checked both of them.

I was using the buggy one for a long time and games like mario vs DK worked fine. Eventually tried yoshi and It crashed.

The best way to tell if you have the right one is by checking the way exophase says to in the readme as I posted in my previous message.

I had never used a hex editor but with a few quick google seaches its easy as.

Download this freeware hex editor.
Run the program
Drag the bios file into the programs window and it will open it
In the grid of numbers, the very first (top left) should be 18, not 14.

If your bios is 14, keep googling for another.

Also, no official release of VBA will come with a ripped official bios, warez versions may.
Also note that of the 2 (legally questionable, not in any way supported by exophase, hosted on less reputable sites than this) 'complete' packages of gpSP i found that came with the bios , neither had the good one.

If I could find the right one in about 5-10 mins of googling it cant be that hard.

thanks for the info and the hex editor
And yeah mines the real one and i noticed in the same folder i had NO$GBA so it might have came from there.
and i dont download files off untrustworthy sites i only ever download from the offical sites
