This is the home of the Apple2 portable Apple //e emulator. It's based on GCC and SDL2, and runs on Linux, Windows, and MacOS X. It's powered by Virtual 65C02TM, and sports an easy to use yet powerful interface.
This emulator came about because of ApplePC. It was a DOS only application with a horrible interface, and you had to tune it to get it work at the correct speed for your machine, but it had absolutely to most accurate looking screen that I have even seen on an Apple emulator at that time and ever since. Current emulators still to this day can't match the fidelity of what that old DOS program could do. So, to make a long story even longer, ApplePC disappeared off the face of the earth and I thought it was a shame that the screen rendering of that emulator should disappear with it. Also, there are, for some reason, absolutely no Apple II emulators for Linux! A deplorable situation! And so I resolved to fix that situation by figuring out how ApplePC did its video tricks and by writing an emulator for Linux.
Currently, only a source code archive is available. More will be coming in the near future... You can get a copy of the source code like so:
git clone http://shamusworld.gotdns.org/git/apple2
