Thanks for the info on AmiKit, that looks very interesting. Though it's still a shame about the AIAB site - the site was useful as it also had loads of additional applications and games available for download, also in a format ready for WinUAE.
(As an aside, I can't help being curious by some of the Terms of Services for AmiKit, e.g., #1 about non-military use or #3 about copying parts of the archive, given that AmiKit essentially seems to be a compilation of software by other authors? I'm wondering if this would be a violation of the licences of some of the individual pieces of software, e.g., the GPL says "You may not impose any further restrictions on the recipients' exercise of the rights granted herein."? I don't mean to be picky, as it's obviously good that people are producing things like AmiKit, but we should be careful of imposing terms on other people's software...)
