Songbird Posted February 8 Share Posted February 8 Spent a couple hours trying to figure out a bug in Microvaders where collisions stopped working when the screen is flipped by the user. Kept scratching my head thinking the coll bit was not set in the SCB, or the coll value was changed, or the coll buffer address was changed. Turns out I forgot NO_COLLIDE is in the same SPRSYS reg as LEFTHAND. Apparently there was a 30-year-old bug in the Lexis code that never set this value properly for the hidden game. Corrected the value and now it works. There. I feel better now. 3 Quote Link to comment Share on other sites More sharing options...

42bs Posted February 8 Share Posted February 8 SPRSYS is not RMW! This trap got many good programmers. Some came out. Congrats Carl 🙂 1 Quote Link to comment Share on other sites More sharing options...
