Anyone know how to get Space Crusade to run on an A3000?

Specifically: A3000T, 2M Chip, 8M FAST, 3.1 in ROM
or softbooted 2.04 or 1.3

I've tried Degrader 1.30 to disable FASTRAM, set only 1M Chip,
disable caches, do the privilege thing:
but although I get the start up screen from the game, and it
then offers me some flags to choose a language, whenever I click on 
a flag the machine just goes blank. No further disk accesses.

Any ideas? Is this a complete non-starter?

(It works ok on A500+, 2.04, IM Chip, 2M FAST, A590)

Thanks.
