Most games were made for a bog standard A500 with 1 meg RAM.... Anything different from that is expected to give problems mate. WHDLoad fixes these problems.
Very true. Floppy-based games especially from the A500 era do lots of nasty hardware tricks. Some (most?) of those aren't 100% compatible with the A4000. Very few things will work by powering up, popping in a floppy, and hoping.
You can try various step-down tools like
Degrader
options:
50hz (or 60hz if you have a PAL system and need an NTSC only game)
50hz system (ditto)
NoView
or
Tude
option:
Kick 1.3 (make sure you HAVE a kick13.rom where it looks for it)
They help and boost compatibility quite a bit, but WHDLoad is 100x easier and more reliable. Even games that claim A4000 compatibility sometimes expected you to know you had to do these things. Back in the day, compatibility often meant that you might be able to get this to work if you shut off every expansion, boot in an improbable configuration, and you're feeling quite lucky on the 2nd Tuesday of the month...
