Wow, quite a few of you then! Cheers everyone.
That's made me feel all happy and stuff. (nothing sexual)
The beta will come as a standard zip package with all the necessary files inside. It'll come with both an icon to start it from and a startup sequence should you want to boot it on it's own (which I hope some of you do because I need this testing!).
I'll whack together a small text file with instructions on the very few adjustments you'll need to make to your system (libs, editing whdload.prefs etc.).
It'll come with the complete database, but you'll need to make sure you unpack the games (the ones from my packs, nothing else is supported) to whatever gamePath(s) you specify.
