Yes, a Saturn CD-R with SMS Plus and a usual CD-R (no IP.BIN) with ROMs.
Furthermore, I would appreciate a file browser instead of the current solution. Currently you can only see one file name at once and it depends on the loaded ROM how fast you can switch to the next. Due to this, with a lot of ROMs it happens to skip several tens of ROMs at once, so you are unable to select the ROM file you want to run.
