The 1st time I've worked on pace in 2009! :o
Arnim Läuger has taken my 1541 core and got it reading and writing on his own floppy implementation. He has made a few improvements/fixes in the process, and was kind enough to send them back to me.
I'm in the process of integrating them back into the PACE tree. Since I hadn't touched the C64 project in a while, it was horribly out-dated and took some time to bring back to a compliable state. It compiles now, the C64 itself runs, but the floppy is unresponsive. No great surprise - it's a first-pass update/merge at this point.
I'll look at re-doing my own floppy emulation. I might regress a little and do a flash/SRAM version much like I did for the WD179X - no need for a NIOS. Be nice to get reliable read/write support happening (again) like Arnim. Then I'll look at re-integrating the NIOS core and FAT-based disk image.
