Also sorry but I don't think these extra splits for TGM2 are a good idea. Main reason being - when any of these codes are active, you are not prompted to enter your initials should you get a high score. If the game thinks these codes make enough of a difference to disqualify someone from ranking in, then it's not a good idea for MARP competition either.
If you still want to play and show off on these extra modes, there's nothing stopping you from making a thread and uploading the recordings as forum attachments. I'm pretty sure people would watch them
I just don't think these extra modes are suitable for the main site.
