Thanks - that was the last one in the list; all of the starting weapons, missiles and fields have now been done and reinserted. The 'hidden' upgrade weapons have been done too, but I'm not that far into the game where I can check them yet
Now working on 'items', enemy names and battle screen text/menus. At this point it should be perfectly possible to play the game normally without guessing any menu options - they've all been converted, including the mecha edit screens (what a lot of menus and options!).
Story/gameplay dialogue hasn't been touched yet, but it's all straightforward formatting unlike most of the ship screens, so has much less in the way of control codes and double height characters to mess around decoding.
I wish I had the dumped and converted SNES script for that part though - doing short phrases, item/weapon names and menu entries was always going to be the easier bit. Actual story needs to be handled carefully to avoid it being turned into a nonsensical mess.
