Actually, my HxC .d64 conversions started working when I began writing them back with an ancient 48tpi, single-head, full-height drive. I overrode the setting so I could use Index mode (since HxC aligns the tracks) and voila. I am assuming 300 RPM made the difference. I am using the current development snapshot of HxC which is 2.5.6.9. The drive is an "MPI model 51" from 1984.
I emailed an HxC converted scp file to data (NickFaldoChampionshipGolf.7z)
Do you know which jumper will control the speed on a JU-475-4?
Edit: I found the BX jumper which changes speed to 300 RPM.
And.. yes, I can't get a good write from the HxC image with JU-475-4 even at 300 RPM. It looks OK, but gets a read error around track 32 or so (bad sector) when booting above game on real 1541, and imaging a d64 from the disk again from SCP gives me an image that won't run in VICE - it crashes at the crack screen. However, I do get a working disk from the 48 tpi drive, although you must override to force index write.
