I apologize if this is in the wrong spot. I have come across two GBA games so far that require the BIOS to be disabled (SVN577). They are : Riviera - The Promised Land and Sword of Mana. With BIOS enabled in Riviera, the game gives a horrid sound on a black screen right after the Licensed by Nintendo screen. In Sword of Mana, you can get up to the name creation screen, then a black screen. With BIOS disabled, both games run great. I hope this is something helpful. Thank you to the whole team for such a great emulator that has brought hours of joy.

Thanks for the info, we'll look into it.

That is very nice information. I became interested in that above all else concerning VBA since I first looked at the configuration system for it.

I just tested that with "Sword of Mana (Europe) (Fr,De)".


I have two BIOS files:

Issues: (Black screen, no sound)
Size: 16384
CRC32: 15e1f676
MD5: e60e599135009129b288988a1cba91df

No Issues:

CRC32: 81977335
MD5: a860e8c0b6d573d191e4ec7db1b1e4f6
SHA1: 300c20df6731a33952ded8c436f7f186d25d3492


What do we conclude from that?

This problem is related to a corrupted bios, i know of and have used the bios in question that the op is using, and i know that it crashes a few more games then the ones listed (it also breaks Yu-Gi-Oh, Duel Academy).

Redump, or what/ever the bios and try again.

Thanks to everyone for the explanation and help, the issue has now been resolved.

That's the reason I suggested a long time ago, to add a bios check, so that we can point the user to the bad bios file, instead of letting them play their games without knowing that they have the wrong file.
