Help! My CPU is too fast! (Ain't life a bitch?)
This is a note to all game software developers. Please consider the
fact that some Amigas are running on 68010-20-30(?)s. If
you depend on instruction loops for timing, then the games run
much faster on these CPUs.
An example is Space Harrier. I wondered why I did (fairly) well when
I played it in the store, but couldn't get past the first level
when I played it at home on my Amiga 2500.
A simple boot in 68000 mode solved my problem.
There are some games out there that are not affected by the speed
of the CPU, Crystal Hammer for instance. So, I know that it is
possible to do your timings by a CIA, raster interrupt, or whatever.
So, the next time you are developing a game, please be considerate
of us poor 2500 owners. :-)

While Tracers uses the timer device for its timing (so it should run properly on a 68020), it should not slow down as much on the '020 as it does on a 68000 when things get really, really fast. I can't wait to try it and hopefully I'll be able to soon (2620 on order...) -- -- uunet!sugar!karl | "Nobody hipped me to that, dude." -- Pee Wee -- Usenet BBS (713) 438-5018
