Support for DMK disk images #15

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
This is the disk format that is currently also supported in openMSX (in the 
latest SVN versions). We think it supports all possible copy protections 
currently used on MSX. Most games expect a CRC error on a sector, other try to 
read more than 9 sectors on a track, etc.

This should all be supported now in openMSX.

Would be cool to be able to play these DMK dumps also on a real MSX with 
Nowind. :)

The nowind interface works at a sector-level. Implementing this feature would 
require new hardware for emulation of the diskinterface itself.

Why would it require new hardware? "All" you have to do is put more data over 
the line which gives the details on the disk used... I agree that it would 
complicate the Nowind ROM in lots of ways...

After the discussion in Nijmegen, are you willing to reconsider? Still not high 
prio, but it might be quite interesting :)

Point is that you don't need to emulate the FDC at all even for DMK support. 
BIOS/diskROM level support remains fine. But with DMK you can simply specify 
bad sectors and other details that can be passed through fine with the diskROM.

Yes, if what we discussed in Nijmegen will work then the support can be 
implemented on the host side, no ROM changes needed.
