Cheers Don.
I use modding as a way of learning the software.
I've only recently started using inkscape, as I got sick of pencilling in individual pixels.
Despite the overlap error, I have imported into inkscape, traced some vector shapes over the map.
Exporting back out into GIMP should be straightforward enough.
It's interesting to compare work flows.
Modifying each individual tile... I don't know how you can do it.
I've had this game for a while, but considered modding it nigh on impossible. (Until I discovered batch changes).
The only other game I've found impossible is Advanced Tactics, the folder structure there leaves me scratching my head.
As for this one, I think I may have a suitable workflow.
Put it's going to take some time.
This may well be a modding AAR.
Attached is a really basic trace of the tile map.
But first it's about putting together all the low level tiles onto a single page.
Then into inkscape for some serious learning.
(Ron if you're reading this a dropbox link for Don and I would be most welcome!)
