Use Echelon selfboot tutorial to remake a CD.

Otherwise, you can do this :
1) make an image of your original game
2) hex edit the whole image
3) look for "SEGA SEGAKATANA" in it
4) you should find something like this :
SEGA SEGAKATANA SEGA ENTERPRISES01E1 GD-ROM1/1 JUE 0799A00 HDR-0159 V1.003
=> change the "0" after "JUE 0799A" by a "1"

It might not be exactly the same string of characters, but the "0" to change is at the same place (i.e. 61 bytes after "SEGA SEGAKATANA").
