I've been wondering about joining this project but now I've made my mind.
Are there any databases needed to create?
I now have almost 3 free months and I'd love to help the community onwards. You can see all my other XML-work through my profile if you need any convincing.
I have recently made db's for Acorn Electron, Acorn Archimedes and sometime ago I also created XML's for Philips CD-i and Fujitsu FM Towns. All of these XML's are yet to be tested and double-checked but I'm sure they cover something like 95% of the titles released.
