LBAWin is a Windows-native port of LBA (you still need to own the game to use it) written by one of the developers from Adeline who worked on both games, Sébastien Viannay.

See here for more details:

Obviously http://www.magicball.net/ itself counts as another valuable resource!

What else is (still) out there?

We think we have built up a fair number of tools at mbn over the years - not just lbawin, but also trainers, fixs, hacks, text-editors etc. I think most should work with this release, but if we find stuff that don't we will start to note it down.

Also, check out the fanprojects. LBAnet (and LBA MMO!), map editors, prequal game...a lba swede... :P

LbaWin works!
