This is the Mario ExGFX patch. It will install an ASM hack which will enable you to insert ExGFX for each seperate level and the titlescreen for GFX32 and GFX33. The ExGFX files that should be used should be the same size as the ones included inside the patch.
This version fixes a pretty serious bug where garbled graphics are uploaded in places where player ExGFX aren't used.

While i personally prefer Alternate Mario ExGFX, this patch is a good alternative and does have a few advantages:
-while not as flexible, it also allows for different Animated graphics per-level
-it uses compressed graphics, which (usually) take less space
of note, you can improve loading times by changing compression to "Optimized for speed" in options->Compression Options for this ROM...
I'M DONE FOR! This patch must have one of the hackiest ways to add SA-1 support! <_< For this reason: There is no warranty that using this patch on a SA-1 won't break!
Also made it possible to speed up the loading time a bit by storing the graphics number into freeRAM and only upload the graphics when the graphics differ from the previous room and adjusted the readme. Oh, and also fixed a glitch in which the credits break with this patch applied.
