@All
After reading all the threads about nightlong on os4 there and in google, it seems that for most users there are no video modes shown in screen requester for PPC versions but only Pal ones, so they use the 68k 1.2 version.
I use that one as well but have some strange trashy pixels around the main person (which didn't disappear even if i disable composition and switch to 16bit wb). See:
https://youtu.be/aeun2RnI6gISo to just play a game as it is expected to be, it's enough to understand from where those trashy pixels come and how to fix them.
But what is better, is to understand why the PPC version didn't show a list of the necessary modes (see begining of the video). Because bigPPC version is interesting to use due to fullscreen movies.
Maybe it is possible to somehow cheat those "fakenative" modes, i.e. those Pal ones, so they will produce something and not mess and the PPC version can be used?
