ok try the new version i uploaded. THe LHA contains 2 exes
rott.exe -> use this one with registered wads
rott_shareware.exe -> use this one with shareware wads
both have 030 speed bump and a new LOMEM option that mallocs 4meg rather than 8. Hopefully this will help duga and other A620 users - but this is EXPERIMENTAL
corpsicle i dont think the new build will help, im still trying to understand your issue. what is the exact error and where exactly does it crash for you?
