One thing : I use Batocera on 15KHz CRT screen : FS-UAE doesn’t work at all for all version of Batocera ….
Agree, on 5.26 I can run Amiga WHDLoad games (zip folder) on OCS/ECS and on amiga1200 only with P-UAE. But when I tried LHA files, the game doesn’t lunch.
Amiga was my second computer (My favorite computer) and my first game was xenon in 1988. So I tried it :-)
in 5.26 in A500 or A1200 :
ADF version the game is slow … in zip(ADF) format it’s the same … (BUT these work fine with 5.25 !!! Amiga500/1200)
In WHDload, the game is just fine !
I remembered that i tried amiberry on RPI3B with the same issue with this game (only WHLOAD was good).
You can see my post : https://forum.batocera.org/d/1514-amiga-problems-solved and the solution of WHDLoad on RPI3B by nadenislamarre and kara2010 :-)
Have good day :-)
