@Weedy_Weed_Smoker Using the core with dynarec i got in Hercules to the transition between levels 2 and 3(the game always freezes there) and took a snapshot. Then I booted from a snapshot on the core without dynarec r19 and managed to load level 3!
Since this was the most difficult place(there was a freeze in it with any BIOS), then all other freezes most likely will not be there anymore, but I can reliably check this only with graphics acceleration.
