@Aladin,
post #1
the real requirements are for OCS ECS:
1MB chip minimum, no fast needed — a stock 512KB-chip A500 does not fit (the game needs ~600KB of chip before caches), so it's "1MB chip" rather than "fast RAM" that gates it.
Kickstart 2.0+.
Fast RAM, when present, is used automatically (the MEMF_ANY pool lands there first, freeing chip) — it helps but is optional.
i've tested myself with adf version of the game
cheers!
