Hi, since stuff like RepMastered, cwal.gg, replay extractors/analyzers etc. exist, I know people out there know some things about how to extract/manipulate the data from Brood War storage file formats. I'd like to edit one simple thing - something about the user id/battletags from multiplayer save (.mlx) files; I assume this can't be too hard. Does anybody have a way how?

In case it helps, the reason I'm asking is because I want to be able to save in custom games vs a friend, and then swap places (like would be possible using SC2's continue from replay feature). I thought I could just send him the .mlx file and have him host it, but it seems like there's something in the file that remembers the account or battletag associated to each player - no matter whether it's me or him hosting the save file, the custom game ends up assigning both of us our original player slots, without an option to switch.

(PS. as a more out-there bonus question, I found that back in the pre-remastered times, someone made a tool called playrep that could save a .mlx file from replay, which would be cool; does anyone know how to do this now?)
