So I made this based on the concept by Kobazco used for his FE8 Weapon Reversal hack. All units, including enemies, have had their classes swapped to one that has weapon triangle advantage over their original weapon(s).
All player units and bosses have unique palettes.
Please let me know if there are any bugs or you have any balance suggestions.
Link to doc with credit for animations, map sprites, and class cards used in this hack is here.
Patch it over an unmodified FE7 Rom.
also this is a patch without weather movement penalties and also using x3 effectiveness.
Have fun!
