View Full Version : Neogeo Mvspsp Psp-slim "BIOS NOT FOUND"

September 17th, 2007, 05:37
I have a problem getting MVSPSP 2.0 to work on my PSP-SLIM (3.6 M33).

After i cached the roms and copied them to
"F:\PSP\GAME\mvspsp\cache\ncombat_cache"(ninja combat)

I then copied the original rom to the roms folder.

Then, when I try to load the roms, I get a "bios not found" error message.

my questions are:
1. where do I get the bios? where do I download it?
2. How do I install the bios? what directory?
3. do i copy the 2 cache files directly into the mvspsp\cache directory? or do I copy the entire "ncombat_cache" directory into the mvspsp\cache directory?

Assistance would be greatly appreciated.....:confused:

i finally found out that you put the bios into the roms directory ZIPPED!!!

i swear some of these readme's have the msot obscure directions ever!!!!!!

question again....when I play magicial lord...i get a vertical sync problem...a dark line keeps occillating up and down the screen.

also, its especially laggy when I am in the mvspsp menu. its almost like the controls wont respond to my directions of up and down when im only trying to select a rom. Whats up with that?

ok.....so apparently if i use the ad-hoc version of the emulator it solves the vsync problem and the slow menu problem....

man...im going to write a guide for this...for all people even noobier than myself (however few). so that everybody can use mvspsp and not have to worry about obscure instructions or readmes
