RetroArch: Mega/Sega CD Bios (May affect RetroPie&UltraSlim)

Thu Aug 07, 2014 6:42 pm

I have just been doing some testing with the newest version of RetroArch (v1.0.0.2) and have encountered an issue. When running PicoDrive Mega/Sega CD Titles wouldn't run (No Bios Found msg). However, after a little research and tinkering I have found the solution, it requires changing the File Name

Old Names Required for Bios
Mega CD (EU): eu_mcd1_9210.bin
Mega CD (JP): jp_mcd1_9112.bin
Sega CD (USA): us_scd1_9210.bin

New Names Required for Bios
Mega CD (EU): bios_CD_E.bin
Mega CD (JP): bios_CD_J.bin
Sega CD (USA): bios_CD_U.bin

As I have indicated in the Subject Title, it MAY affect RetroPie and UltraSlim if updated (as they are based on RertoArch). Hope this post helps users experiencing similar issues.

Is this with the new 1.1 Retroactive version? This info will come in handy, thanks!

No, its version 1.0.0.2 (post amended). Looks like 1.1 is going to bring some sweet changes, hopefully with a good/useable Vectrex Core!
