Just going back to the Chip Ram issue and what Bippym said. I agree 100% in regards to a game not loading if its allocated itself with 1.9meg of Chip Ram and if only 1.8 is available, it will not load. I had many a game not load due to this case, with Capital Punishment being a prime example. Fast Ram certainly helps ( Overkill is an example in this case ) but again, not enough Chip Ram and the game just wont load.. Nothing to do with slowing it down.
In a nutshell -: If it loads with only 2meg chip available then your in luck \
If it wont load through workbench, bring everything down to 4 colours and remove the backdrop.
If it wont load like that, then boot with no startup - assign the game disks and directories then execute the game.
But of course, the main issue here is slow game performance ???? .... I run Zool 2 with my own 030 with my Workbench running in 128 colours and 32 of Fast Ram on an A1200 and it loads every time with no slowdown.
Fast Ram is a bonus if it runs and it "will" smooth some games out.
