I have datted all my roms with the newest No-Intro DAT file.
On a CD from 2003 i found a file thats not recognised by ROMVault and i cant find it in the rebuilded SNES set.
Its a SNES test ROM.
There is a "SNES burn in test" in the rebuilded set, but that is not the ROM i had on CD.
I dont know if its a hidden gem, but if anybody else wants it, here it is.
