C64 Emulator written in PHP

For the love of everything that is holy, why, oh god, why!!!!???!!

TODO:

• Complete the debugger
• Load C64 disks and tapes (we can do PRG though)
• Enable SID
• Fix up VIC sprites

Bugs & Things

• Many.. but we have a functional testsuite that passes (hurrah!)

Running the emulator

Since PHP isn't really capable of displaying graphics (PHP-GTK, maybe), we are using a shared memory block which is read from a python (2.7) program (monitor.py).

This means that the following must take place:

• Make sure you have pygame installed: pip install pygame
• Start the monitor: python monitor.py
• Start the emulator in another console: php c64.php

Files

• c64.php <file.prg> Actual c64 emulator (with shm monitor output)

• c64-debug.php <file.prg> Actual c64 emulator with debug information visible

• c64-ws.php Websocket edition. Use with web/index.html to display monitor

• c64-debugger.php Full debugger. Still much in progress.

• c64-test.php Functional test system for all opcodes. Seems to be passing.
