Twoapple is an Apple II emulator written in D, licensed under the GPL v2.0. It lives at

http://code.google.com/p/twoapple

It doesn't do much yet in the way of Apple emulation, but 6502/65C02 processor emulation is working. Next to come will be monochrome video output.

You can grab the source using Subversion:

svn checkout http://twoapple.googlecode.com/svn/trunk/ twoapple

I wonder if there are any other 6502/Apple II enthusiasts programming in D?
