SA-1 Pack

SA-1 Pack is a package of patches for activating and optimizing the SA-1 system for Super Mario World, with emphasis on eliminating slowdown, game limitations and accelerating the engine to the maximum possible. Unlike SA-1 Root, SA-1 Pack is focused for ROM hacking and it includes several features for implementing new features for the game using the chip.

Being the most complex patch made for Super Mario World, SA-1 Pack requires to all other ASM patches apply a RAM remap for warranting compatibility with the patch. However, without the RAM remap, it would have been impossible to accelerate the game because the SA-1 chip cannot access the S-CPU work memory (WRAM).

For implementation details, see SA-1 Root.

MaxTile System

MaxTile System or just MaxTile is a new feature introduced on SA-1 Pack v1.40 that fixes all known OAM issues involving the game, allowing custom sprites using both $0200 & $0300 area and implements a basic sprite priority system for custom resources interested in using the MaxTile API directly, while still keeping compatibility with regular and custom sprites that weren't designed for MaxTile.
