# A-Team: an Atari 2600 disassembly with PAL conversion

> A two-bank 6502 disassembly of A-Team for the Atari 2600 assembles with DASM and doubles as the basis for a PAL conversion. Compile switches pick NTSC, PAL 50 Hz or PAL60 colors and timing, and toggle the intro logo and intro glitch fixes, the level-1 border color cycling and a bug fix that keeps the scanline count fixed, each with the original behaviour available. Comments mark the color register writes for backgrounds, characters, missiles, the score panel and the intro screen.
