Medievil 2 PAL save file corrupted on Memory card 1 #81

Closed Ichisuke83 closed 2 years ago

Ichisuke83 commented 2 years ago

Using Unirom with freepsxboot on Memory Card in slot 2, Medievil 2 won't allow you to load the save file from memory card 1, telling you that the save file is corrupted while is not. I'm using latest 8.0.J version. Medievil 2 is PAL version. Game works and load save file just fine if boot with Unirom through an action replay cartridge or other methods. So I think there is something wrong with how Freepsxboot disable slot 2.

What is your BIOS version? I have an updated patch which should fix such issues, it would be great if you could try it and give feedback.

Oh I can test this on a 102 with 4.4 Bios, on a 7502, 5502 and 1002 (2.2 BIOS).

Ok, you can try this on the 7502: https://github.com/brad-lin/FreePSXBoot/files/8310007/freepsxboot-unirom-fastload-20220318-bios-4.1-1997-12-16-A-502224b6-slot2.zip

Yes. This works fine. So I suppose you have to update all the versions...?

Nice, thanks for testing. This new version will be released soon (in the coming days), the updated images will be uploaded first in the repo.

Sorry, is there a date on when the new version will be released? Otherwise can I have a version for the SCPH 102 4.4 BIOS? Thanks.

I have just pushed the new images for all BIOS versions (no release yet, but the images are available from the links in the readme). Feedback is welcome, thanks.
