This pack of patches enables the SA-1 chip on your ROM and modify almost all SMW engine to make the sprites (including non-standard) and blocks processed by SA-1, killing almost all slowdown on level and overworld and decreases the level loading time. And as a bonus, it increases the maximum number of sprites on screen to 20 and per level to 255.
Additionally, it includes a couple of minor optimizations, like the circle routine used on level ending.
With this, almost all slowdown possible in-game disappears.
Increases the maximum amount of sprites *on screen* to 22.
Increases the maximum amount of sprites *per level* to 255.
Moves the sprite processing code to SA-1, making all sprites gets processed 4 times as normally
Optimizes some routines to make the level loading faster.
Moves almost all non standard sprites, such as shooters, generators, cluster, extended, minor extended, bounce, score and smoke to SA-1 CPU.
Moves the block/map16 handling to SA-1 CPU.
Moves almost all overworld code to SA-1 side, leaving minimal CPU usage on overworld.
All other SA-1 features like 6 and 8MB support, 10.74 MHz CPU, Character Conversion DMA, fast RAM, etc.
This version fixes various known bugs, such as the blue shelless koopa not catching shells thrown from behind and some mode 7 bosses on ZSNES. Also it updates part of the documentation considering the current hacking scene.
I notice a bug in ludwig boss fight about the item being dropped from the item box goes behind the sprite background (assuming you must've messed up the OAM order). In the normal original smw, it was fine.
Not much of a problem, since smw bosses are not often used on smw hacks.
