Bug Fix:

Featured:

Description:

This patch frees up 387 bytes of RAM at $7F:8000.

This fixes an bug that causes stall in SPC (when Addmusic is used) and additionally frees up more cycles by reducing the cancel out RAM routine creation a bit.

Update (Major Flare): Made the patch SA-1 hybrid and Asar compatible.

Note: if you use UberASM Tool, check the README file provided.

This is out of AddmusicK's scope (the Addmusic referred to here pre-dates AddmusicK) because AddmusicK uses $7F:B000, not $7F:8000 for FreeRAM.

not compatible with sa1-1.33 or retry or other patches and not with addmusicK 1.07. Hmm what is this: Code org $0086DA autoclean jsl Unroll_OAM_0391 <----that should jump Code .OAM_0391 PHD <----that label dosent exit as are jump location PEA $0300\|!addr If i am not mistaken it should look like this: Code org $0086DA autoclean jsl Unroll_OAM_0391 Code Unroll_OAM_0391: PHD PEA $0300\|!addr

Tested with: Lunar Magic 3.11, asar 1.71, SA-1 1.32, UberASM Tool 1.4, bsnes+ v04. Works correctly, so accepted. A kind of niche patch that could turn out useful for more advanced users who wish to have more free ram at their disposal. During moderation I made the patch compatible with UberASM Tool and added the readme file (make sure to follow its instructions if you're using UberASM Tool, or the game will get stuck upon loading!).

*$7F8000-$7F8182, which is originally the unrolled loop for clearing out the sprite tiles. Combined with free $7F0000 (frees up $7F0000-$7F3FFF) and you have 387 + 16384 = 16771 ($4183) bytes of freeram.
