I backed-up Chaos Legion with no problems.
PrimoDVD built the ".gi".
Wrote to Ritek G03 in 2x speed in Record Now.
Used a Pioneer A05 to build the image and write the file.
Played on a V4 w/Messiah 2 (though I do notice a markedly slower load time from my original, which I also notice with other Capcom games as well...)
