Quote from: Dr. Floppy on October 25, 2015, 06:13:33 AMIs there any particular reason the OP's might have done it this way?
QuoteDo any other NES games exhibit this odd arrangement?
Quote from: Bregalad on October 25, 2015, 05:53:25 PMNES games that does most of the work in the main thread does indeed have a game loop, but the amount of time in each iteration of the loop is typically one frame, so there is not what you mentioned (a varying amount of time elapsing between them). The NES is not technologically advanced enough to make such an approach practical.

Quote from: Dr. Floppy on October 28, 2015, 06:38:58 AMMakes sense. First thing the SMB1 NMI Routine does is clear d7 of $2000.
Quote from: Dr. Floppy on October 25, 2015, 06:13:33 AMThe game starts up at $8000 and proceeds to an infinite loop at $8057.
