First public release of my little C64 emulator. Don't expect too much, it's only a "fun project". ;-)

20 PRINT "ABOUT"

AC64E simply means Axel's C64 Emulator. I've been working on it since 06/2003 – compared to other emulators out there it's still a really buggy alpha, and it will remain in this state forever. ;-)

I've been fascinated by the emulation scene since I first started a C64 emulator on my good old Amiga. I loved the C64 too – and crashed two of them back in my youth. I love the C64 and I love to code, so why not code a C64 emulator? I had nearly no idea of C++ when I started, so it was a hard task in all ways.

All parts of the emulation are 100 % my own work (OK, I got some help with the opcodes ADC and SBC). That's why it's so buggy, I guess. But hey, I'm proud of it. :-)

Most opcodes are fine. JMPI, ARRB, SBXB, SHAIY, SHSAY and LASAY still fail the testsuite.

VIC-II40%

Text, multicolor and bitmap mode, simple sprites with stretching.

CIA10%

Keyboard input and joystick 1 (cursor keys and space).

Runs on Windows, loads games in .PRG format, OpenGL output via freeglut. Next up: a better multicolor mode, D64 loading – and much later, SID emulation.
