Any other issue may be caused by patch incompatibility, so I will need a list of all the other patches you applied to your ROM to figure it out
For the sprite frezzing the game, wich block number did you inserted the block as? this is very important since it use the block number to figure out which powerup to give and which graphic to use, so if the number don't match any inserted powerups, you get a glitched mess that freeze the game when you touch it
The only patch I have is the Separate Luigi patch. Thats probably the problem with the Mario gfx's
I set the blocks to 400-40F like one person said.
