The first episode of the Ztar Attack series is now out, after a long time ! With 170 stars, 15 main levels, and extensive worlds, it's the biggest non-extreme hack out there. Difficulty is like Escape from the Jail (aka close to 74 but with some harder stages). You might have trouble with the end of the game if you are new to sm64 hacks, however it's far from impossible and should be alright if you are already good with sm64.
Original game by Nintendo, title screen by Mariocrash.
Special thanks to the betatesters : aglab2, gatopumuky, Mazerns, Lunhazel, Mariocrash, Nerghray, MisterAlekss and mopplopmopplop :P
