This is my first test-sprites I'll be using. Also, is there limit on how many sprites I can uses, like only on 4 layers, or I can [literally] put millions of unique sprites in one game using different files auto-load and other-files?

one 512*512 graphic page for sprites 512 sprites that can be shared between the two screens with XSCREEN XSCREEN [type],[sprites on upper screen],[bg layers on upper screen] so if the upper screen has 100 sprites, the lower has 412 thats without saying that keeping track of sprites is a nuisance, unless: VAR THE_SPRITE% = SPSET(0) assigning a sprite to a variable :o

But is it limited to 512 or it can swap those sprites with like hundreds of files for unlimited sprite in one game?

it can, as long as it fits in a single gpage

AWWWWWW YEEEAH!!! What code does that?! [Is it the above? Looks like sprite organizer]
