Well progress is slow again although I swear FirstGen is not abandoned! Just the other day I was tweaking maps 2 and 3 adding in some more detail, and altering some scripting.
A new version of Edge, the source port I'm using, is about to be released anytime now (I've been beta-testing it actually) which will bring it up to 1.28. It runs a bit smoother and faster than the previous version, and numerous bugs have been remedied. At the moment it seems like nothing has "broken" in regards to FirstGen/Edge 1.28 compatibility :)
