Latest C64 core will not load disk images
Posted: Fri Jul 30, 2021 10:00 pm
I have the latest C64 core dated 21-07-01 installed with the JiffyDOS ROM image and it will not load disk images. I mount the D64 file from the OSD, then press SHIFT+ESC or F7, but I get a "device not present" error.
If I load up a slightly earlier version 20-11-08 of the core from 2020 with the very same JiffyDOS ROM image, then I can load and use the same D64 files just fine. All common configuration settings betweek the two core revisions are the same, as far as I can tell.
Any ideas on how to solve this? I've tried erasing core version 21-07-01 and reinstalling it, however it didn't help. I can load CRT and PRG files okay, it's just disk files that fail to load. I haven't tried tape files, because I believe JiffyDOS doesn't support tape loading.
I tried using DolphinDos and even the standard C64 kernal, but they each give the same error when loading from disk: "device not present error". It's almost like the core cannot detect the virtual disk drive.
I've set drives 8 and 9 to be always present, as well as 'present when mounted'. It made no difference. Parallel port setting is enabled.
I've used the update_all script already to update core MiSTer components, however it hasn't helped, either. For now, I'm using the 20-11-08 release of the C64 core as a workaround and it works flawlessly, but it would be nice to get the latest release working.
