Anyone remembering Splam!? The author is still working on his Commodore64 emulator for the Gameboy Advance. The author has notupdated his page for ages, but recently he posted those WIP news on his page:

Just a quick update to let everyone know I’m still working on Splam when I can and to say thanks for the emails of encouragement I’ve been getting (I’ll ignore the ones just insulting me).I’ve taken Splam apart recently and I’ve been putting it back together slowly and rewriting bits as I go. As soon as I’ve got it all back together I’ll test some games on it and if it looks ok I’ll release something. It probably won’t be as fast as I want it to be (ie 50fps) but shouldn’t be too far off.
