smiggy100 Posted December 11, 2016 Share Posted December 11, 2016 (edited) Morning All I seen Launchbox the other day and loved the work being done here. I have since donated and become a lifetime supporter. However i got to the the PS1 emulation and hit a wall. I have some games that are (Pal) and Most (NTSC) The games that are for Pal when try to load from Launchbox get a black screen. Is there no default command to have Retroarch use a specific Bios for specific games. I have the bios files required as i can get them to work in PSXE but i am trying to get as many working in Retroarch as possible before going with other emulators. How does Retroarch choose what bios to use when launched? is it only working with NTSC bios's ? The only solution otherwise it to find NTSC versions.

Lordmonkus Posted December 11, 2016 Share Posted December 11, 2016 Do your PAL games load in Retroarch on its own bypassing Launchbox ? Quote Link to comment Share on other sites More sharing options...
smiggy100 Posted December 11, 2016 Author Share Posted December 11, 2016 I get back screen still. i can only assume its attempting to use incorrect bios and stops as black screen, Quote Link to comment Share on other sites More sharing options...
Lordmonkus Posted December 11, 2016 Share Posted December 11, 2016 It's possible but its also possible that your disk images are not ones that Retroarch likes. Is the disk image in a cue + bin format ? Also do you have the 3 bios files listed on the wiki page https://wiki.libretro.com/index.php?title=Beetle/Mednafen_PSX#BIOS ? I don't have any PAL region games that I am aware of so I cannot test directly but I believe that Retroarch will automatically load the right bios for the game where necessary.

DOS76 Posted December 11, 2016 Share Posted December 11, 2016 I don't specify my Japanese games and they load correctly in RA what file type are you using RA doesn't like the .ecm file type Quote Link to comment Share on other sites More sharing options...
smiggy100 Posted December 11, 2016 Author Share Posted December 11, 2016 i am current doing a MD5 check on the bios files to see if they are correct and not just renamed. There must be an issue them. Quote Link to comment Share on other sites More sharing options...
smiggy100 Posted December 11, 2016 Author Share Posted December 11, 2016 My MD5 of the EU bios doesn't match the recommended in the Core information for Madnafen PSX Hopefully this is why. Quote Link to comment Share on other sites More sharing options...
