Pong Wars on the Commodore 64

2 hours ago

The post details the author's project to recreate Pong Wars, a mesmerizing animation of two balls battling to flip colors on a 20x20 grid, on a Commodore 64 using 6502 assembly language.
Key implementation steps include setting up the screen and color RAM, using sprites for the balls, managing movement with fixed-point math and sine lookup tables, implementing edge and block collision detection with randomized bounce angles, and rendering the blockfield and scores.
The game loop utilizes raster interrupts to run within the vertical blanking period, though performance is limited by copying the blockfield to color RAM each frame; potential optimizations are suggested, such as direct color RAM access and incremental score updates.
