+Larry Posted July 24, 2019 Share Posted July 24, 2019 My very first Atari 800 had an off and on problem with collision detection of objects and missiles. My Atari was mfgd. in late 1981 -- still with OS A roms. Is anyone familiar with this issue? I never read much about it, but I think it was resolved when I replaced the OS roms with rev. B. Wow! We're coming up on 40 years -- scarry! -Larry Quote Link to comment Share on other sites More sharing options...
Urchlay Posted July 24, 2019 Share Posted July 24, 2019 What kind of problem? Sometimes collisions just wouldn't register? The ROM shouldn't affect collisions... did you perhaps also upgrade from CTIA to GTIA around the same time? Or... maybe it could have been caused by a loose board, which got reseated when whoever did your upgrade took the machine apart & put it back together.

I could "blast the bad guys" with zero effect! Quote Link to comment Share on other sites More sharing options...
