The first boss has infinite energy. It is impossible to pass the level. This always happens, even without using cheats.

For installation, I used:
https://whdload.de/games/JoeAndMac_CavemanNinja.lha (latest 2019-11-19).
and Joe and Mac sps 2179 in ipf format.
I just tested the newest slave. The startup problem seems to be gone. However, I noticed some graphics errors at the beginning of the second stage (waterfalls - strange flickering black lines). This is probably due to the type of memory used by winuae. My system and games use 256 MB of Z3 Fast memory. When I turn off the Z3 memory and start the system on the Z2 8 MB memory, the game no longer displays incorrect graphics. Unfortunately, starting the game with the whdload command (executepostdisk = uae-configuration ...), which switches the Z3 to Z2 memory, although it works properly, does not fix the graphics error.

can you test both new attached versions (lha) to compare (with and without FAST mem) ?

note ~0011787

lordelessar (reporter)

The new slave has solved the graphics problem. The game also starts without any problems.
Thank you @CFOU
