Yep, brawlbox does re build the module properly pikazz
There's a couple reasons I like dant's a lot, but one of the main reasons is his module rebuilder parses the module and tags the locations that need to be patched, then i believe he just replaced the id of the previous character with the new one (I think, its been a little while since I watched the stream). Though I use both brawlbox and the module editor 3 when working on modules. But again, the real reason I was interested In seeing it, was just to peek under the hood of the program itself
Brawl box has a few features that are infinitely useful!
you see, in PW module editor it shows you in yellow where the relocation tags are, but if you go to that location, you would never know there was a relocation pointing to there.
In brawlbox, the relocation tags are shown in green. Whereas if you actually go to the location where it points to, the text will be red. Indicating that some relocation is pointed there. And if you look on the right side under 'linked words' it will tell you all the places that have relocation tags pointing there. Better yet, if you double click on one of these linked words, it will open a new window and take you to where that relocation is.
The other thing it does, is tell you the file offset of each of the sections. its incredibly useful in that respect.
