Latest C64 core will not load disk images

Unread post by Fluff »

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.

Verify from the OSD that you have the latest (as of now) MiSTer v210724 and OS v210711

OSD says I have MiSTer v210724 and C64 v210701. Weird thing is, I have been wrestling with this for a few days before posting and it has just now started working. I haven't changed any settings except for some SID settings. Very odd. Anyway, I won't complain, since it seems to be working now.

Great, I'm glad it started working. :)
