Neo Geo Emulator

Well I'm fairly new to emulation on my psp, I've managed to downgrade my psp from 2.81 -> 3.03 ->1.5 and back up to 3.03 oe-A.

I have the neo geo emulator (ngepsp) both the files ngepsp and ngepsp% are in the directory PSP\GAME150.

Now everytime I try to load my ROM (I only have my one favourite Karnov's Revenge) it comes up with an error: CRC32 not correct. "Europe MVS (Ver. 2)".

Do I need to find the Neo Geo BIOS and put it somewhere in the ngepsp directory or do I have to convert the game to a different format (currently it is a zipped file, inside there are 10 .rom files)

any help would be appreciated.

01. Get MVSPSP. It's the best
02. Click on the supplied convertor, which will give you a cache of your rom. Stick your rom in the ROMS folder and the cache in your CACHE folder.
03. Find a working Neo Geo BIOS, and stick that in ROMS too.

Voila! Neo Geo on yer PSP. :)

I've managed to get the game to convert though I'm just curious about the bios. I have the emulator NeoRAGEx for the PC can I take the bios from that emulator and place it into the psp emu??? if not can I get it somewhere else (I know talking about iso's is banned but is talking about bios's banned as well?)

Also I was looking on ebay for a new memory stick and noticed that for a 4Gb stick it was around AUS$0 (they're around Aus$320 in the shops) is there a chance the mem sticks are fakes, I don't mind if they are so long as they work properly... has anyone bought one and not found any problems with it?

Yeah talks abt Bios is prohibited by law... well DC emu's law. :P

Instead of asking, why dont u just shove the bios right up ur PSP's @ss? I meant, just try if it work. :P
Dont forget to press START (or was it SELECT?) in config menu to access bios screen. U can also google the bios. Just a thought.

Dunno abt the "Real" 4 gig MS. I got fake 4 gig & MVSPSP run so stuttering. The fake 2 gig should be OK. The the real MS should be even better. Again dunno.
