Fusion 3.51, sega cd help..

Hi there. I am trying to use fusion 3.51 to play sega cd games for the first time and i cant seem to get it to work.

i have downoaded a torrent that had every genesis and 32x game and a bunch of sega-cd bios files. i have tried all of these bios files and i still can't get sonic cd to load. is there a specific bios file i need for this? and if so, a link to it would be great! thank you for any help.

We can't offer you links because it's not allowed. Read the Forum Rules

The BIOS regions should match with the Kega's config ("Options" -> "Set config" -> "Sega CD" tab. Recommended BIOS are (with the most usual names):

USA: us_scd1_9210.bin
JAP: jp_mcd1_9111.bin
EUR: eu_mcd1_9210.bin

Anyway, you also need to load the Sonic ISO or CD, and select the correct drive.
