The tool is on my github, and the artworks are for now http://dspnet.fr/~galibert/artwork/
Wow, thanks for this, you totally just made my day...
Oh, and 'Hi' everyone, I'm Rik... I run www.handheldmuseum.com, and have been following all of this with eager anticipation since I found out it was being done a few months ago... Incredible work all around, I never thought I'd actually see the code being dumped from these games, and now I'm playing Entex Pac-Man 2 on my computer... This is just beyond cool.
You will definitely get some play testing out of me.
