Hello.
I making PC-9801 np2（=nekop2, meow） different core. PC-9801 is PC. It has 2 FD drives and 2 HD drive I/Fs, and CD-ROM drive.
In this core lifetime, exchange FD and CD-ROM no core resets. Probably now ‘DiskControl’'s implementation can’t comfortable these feature.
DosBox is same inconvenience too.
I think someone add ‘MultiDriveDiskControl’ feature.
Thanks.
