(MESS) bw2: Fixed memory mapping. (nw)
(MESS) msm6255: Refactored to use device_memory_interface. (nw)
(MESS) floppy: Added macros for declaring modern floppy formats. The generic floppy formats (D88/DFI/IMD/IPF/MFI/MFM) are now automatically supported in each driver using the modern floppy code. [Curt Coder]
Remaining TODO list:
- take WP into account
- test the amstrad, implement its observational format (edsk) using
pasti as a start. Or find the legendary amstrad IPFs. Or both.
- correct read track, the implementation is completely wrong. See
previous for testing, it's only used in protections the check the
inter-sector gaps.
- shake and bake on the amstrad, protections are the best to find bugs
in a fdc
- add the scan id commands, but nothing seems to use them
- debug the 2.88M formatting which is unreliable. Fix its IDAM/DAM
gap size on formatting too (but that's not what's making it
unreliable)
- test all the systems that were hit, and fix what needs to be fixed.
Beware that multiple problems may happen:
- upd765 may be wrong
- the driver may not be working
- the hookup may be wrong/incomplete (bitrate selection and floppy
rpm in particular)
- the driver may be too limited for the new implementation (the x68k
dma device does not handle non-instant dma yet for instance)
- report invalid command when appropriate depending on the actual chip
emulated
- add the russian clones with their real names
to 8-bit handlers to match the others. To ease
pain, added DECLARE_READ/WRITE_HANDLER macros that
set up a default parameter. Also updated devcb so
that the handlers can be called with or without the
mem_mask. [Aaron Giles]
read/write handlers to take an address_space & instead
of an address_space *. Also update pretty much all other
functions to take a reference where appropriate.
