Hello!

I made a NSMB Multiplayer Hack and wanted to place a roulette block in the pipe level.

The sprite is not red and I just assumed that the game would be okay with it but the game freezes just before the block can appear on screen.

Is it impossible to insert the roulette block in a MvL level?

Greetings!

unfortunately, the roulette block doesnt work with MvsL, even with code hacks to extend MvsL's object compatability. if ya want a list of objects compatible with MvsL, see here
