OK, I got the correct bios files (according to Shikigami's list), and I unzipped the .rom files in my svcplus.zip and renamed them according to the romrc file and I still get the "no valid romset" error. This is maddening!! Where have I gone wrong?
I tried using some other roms such as Metal Slug X and I get that same error. Shikigami, did you have to rename anything to get your SVC Chaos to work?
