La-Mulana runs on RP Flip 2 only if dynarec is disabled #1042
Description
Thanks for your previous help with La-Mulana, it now works great on other platforms. On RP Flip2 (rocknix), it fails to launch with dynarec active. Without dynarec it works but very slowly. Using BOX86_NODYNAREC and binary search I narrowed the problem down to a single address(!), so it runs fine with BOX86_NODYNAREC=0x083aa402-0x083aa403.
Here is the info I have gathered so far:
BOX86_DYNAREC_TEST: No output (surprisingly to me)
BOX86_NODYNAREC=0x083aa402-0x083aa403: Game works!
BOX86_DYNAREC_DUMP:
