Minesweeper for the Commodore 64, written in 6502 assembly
After programming Minesweeper in Java, I felt like trying something completely different, and started working on a 6502 assembly version of Minesweeper for the Commodroe 64. The first mostly-functional version of this program was completed in about three days, and much more work has been done since.
In its current state, C64-Minesweeper supports one board size and difficulty -- a 12x20 board with 40 mines.
Future plans include:
- Compression of whitespace in text screen data
- (Possibly) Add support for custom difficulties (number of mines)
Use the cc65 assembler, cl65, to build the C64
executable with the command cl65 -o mine.prg -t c64 minesweeper.asm.
Use a Commodore 64 emulator such as VICE.
With VICE, right click the mine.prg file and open with VICE, or use the
command x64sc mine.prg.
This program was written primarily for NTSC systems. If run on a PAL C64, the clock on the game status screen will run too slowly. To make it work correctly on PAL systems, change the IRQ_PER_SECOND constant near the beginning of the source file from 60 to 50.
