The intro video in FR is all Lz compressed images and ASM to move them around. I could actually write a whole new one by just decompressing Lz frames to the VRAM in a routine which would replace the intro video. I just don't know how to make it check if you pressed A each time.
Well, in Pokémon Derpizard, all of the Derpizards were completely coherent, so I kind of want to keep it to just physical changes, you know? So instead of the gym leaders and guards being loopy, how about they are sooo confused and starting to be driven mad by the change, that they let you through because you have kept yourself healthy?
ill have to ponder this complicated story lol... but for now... there only seems to be one issue... gettin gto the elite four with 8 badges ends the game... so im thinking you dont ahve all 8 when you get there... infact id assume immediately after the incedend (you placed at the 3rd badge) the player should run up to the elite four... problem is he cant get in... so he decided to continue his quest of getting all 8 badges... but by the time he gets to the 5th badge the gy leader is too confused to battle (as he has become derpizard) so the player heads back to the elite four to try for help, this time the guards along route 23 are derpy aswell... so he can walk by them and get to indigo platau (which is quarantined)
this gives the player 4 badges to deliver the cure (after the presumably long event of gathering the stuff to make the cure with red)
