I have been messing around with the new x68000 core and it works great. My one complaint is that most games require two floppies to be loaded in the disc drive in order to start - one in drive 0 and the other in drive 1.
I was wondering if there is any support yet for mounting roms to the disk drive through command line. I would like to be able specify which disk images go in which drive, and load them both in one command. For frontend tools like launchbox, it would be a lot more convenient to have everything setup with one click, instead of having to go into the in emulator menu to mount that second disk.
