The slow motion effect and kill all enemies does not work while 2pspawn/3pspawn/4pspawn is used for the boss.
EDIT
This is because the boss does not spawn completely if only player 1 is in the game.
Looking into it.
The makeinv is not function and cause the parrow# does not display. The riseinv is also not function.
Fixed and checked code in.
Also made some other optimizations which in turn allows us to have a Max sprite limit of 65,537. Which I believe is more than enough for any mod....lol The raise was about 6.5 times more than previous value of 10,000. I think I could still optimize it some more , but i will look into it later on.....
