Thanks, that's sort of what I'm looking for. With the current tool, I can obtain all the characters in the same game provided I do it right. However, I can't get just all events tied to their respective role as the main protagonist, since there are 4 main characters and you only get to select one who'll be flagged as the main protagonist for all intents and purpose. While the other 3 are just ditched by the game after this choice (along with their rival of course ; basically they're not supposed to exist on the playthrough), I can use a nifty editor to play their starting stage (luckily they all get one) and upon completion the game adds them to the team roster along with their starting unit.
I'm pretty sure there's just a switch somewhere in the save file to determine which protagonist you picked to play the game (how else would they display his/her portrait next to the in-game save?). That
is what I need to edit on the fly.
Look at this chart
to see what I'm rambling about.
For example, let's say I picked the real robot route (female). The rest of the starting cast gets ditched except for her rival, I play through her first stage and she is added to the team roster along with her starting unit at the first intermission pannel.
From here, let's say I'd now like to pick up the super robot (male) protagonist as well. I save my game at the intermission screen, exit the emu and use the editor to change what's considered as the next stage... to the one you would get if you pick him as the main protagonist. I get buggy intro dialogues (the guys are replaced by the actual main protagonist and her rival), then "Stage 2: insert subtitle here", and the super robot (male) characters deploy (yes, the rival happens to be on your side on this route), though they have the same name as the character/rival you picked at the start. Upon finishing this stage, they too are added to my team roster along with their units.
I can repeat that method to get the remaining two protagonists on their starting stages (Which will be called stage 3 and 4 ; what a smart game!) and then continue with the game just as I please (stage 5, 6, 7... up to 99 can be whatever I want)... except that the character I first picked is still the main protagonist! So for the most part, no unlocking upgraded versions of the other three units/convincing respective rivals later, etc... Any combined stage on the chart involves her events only, so that denies me quite a lot of game content. In order to fix that, I need to edit which character is flagged as the main protagonist before picking the next stage. That's not a feature of the editor so that'll have to be done manually... So yes, I guess I could save state in the same starting stage, but with different protagonists. That should narrow down the search a lot if the stage is the exact same... Though if I somehow manage to find a switch or somesuch, how do I locate it in the normal save file?
