Graphic Glitch on Shadow Dancer

[Insert Disk Two]

I have noticed that when playing Shadow Dancer (WHDLoad) there is a graphical glitch when jumping. This does not happen on a real A1200. Any idea how to fix it? Thanks!

What CPU speed are you using? Use original speed and see if that still happens.
Take in mind that the A1200 uses a 14Mhz CPU, and not all games are patched in WHDLoad to run in a faster processor.

On the Amiga 1200 I used an 030 accelerator. No issues.

I checked and yes it seems to bug out. This seems to be some kind of bug in 68020 (cache?) implementation, because if you change cpu to 68000 there is no glitch with same whdload game version.

And by the way, I see massive graphics corruption also in Shadow of the Beast when running whdload version with 68020 cpu. With 68000 it also works fine.

I also own Mist, and under Mist, both games work fine with 68020 cpu if Turbo option is off (turbo has options for chipram, kick, both or off). However, Mister does only have D-cache option, and turning it off does not help (iirc Mister used to have same Turbo option at some point, but it was changed to D-cache).

Strange. Maybe add this as an issue on the git?
https://github.com/MiSTer-devel/Minimig ... Ter/issues

Otherwise, I guess this game, and Shadow of the Beast, needs to run with the 68000 CPU for now.

Btw, might be related to the D-Cache setting?

D-Cache is already disabled on my MiSTer settings.

On Mist core not glitches. On mister core glitches.
