What's wrong with that? You should still be able to swap...I swap 200k cds all the time...
If you want to add dummy data to your cd to make it easier to swap try something like this:
Disc CDROM PHOENIX.DSK
Volume ISO9660 PHOENIX.DSK
SystemIdentifier "SEGA SEGASATURN"
PublisherIdentifier "SEGA ENTERPRISES, LTD."
DataPreparerIdentifier "SEGA ENTERPRISES, LTD."
Lpath ; Path tables as specified for Saturn
Sl.bin is your compiled code, ip.bin is your country code and other startup stuff, leave the text files alone I think their required, not positive, change data.dat to anything you want, its just dummy data. Also make sure you change the locations in my cti file to point to your files.
