I'll also improve some of these rom hacks flaws and give them a lot of fancy improvements, as for the characters, I'm giving Luigi his improved OG SM64 Model by Marshivolt, Wario his model made by StupidMarioBros1 and Yoshi, Toad and Toadette their Team Toad models.
I think I'll add a ton of custom coding and programming that will make these rom hacks better, such as multiplayer, 5 more newly playable characters (Luigi, Wario, Yoshi, Toad and Toadette), several custom objects & enemies, movesets and animations for the new characters, more fun minigames and modes, more levels, more stars to collect, being able to stay in a level after you collected a star, new music, voices for the new characters, many new powerups and some new bosses.
