|02500||$00:A300||144 bytes||Misc.||Mario, Yoshi and podoboos DMA Routine. Used everyframe on NMI during a Level or Overworld. Use by the patch Mario's 8x8 Tiles DMA-er to load 8x8 tiles and Dynamic Z to make all. It use the RAMs 0D84 (1 byte) and 0D85 (20 bytes).|
Mix this with the current 00A300
These additions to $00:A300 aren't very useful -- we already know that it is "Mario, Yoshi and podoboos DMA Routine", "Used everyframe on NMI during a Level or Overworld", and it is pretty straightforward to find out that it uses $7E:0D84 and $7E:0D85 by looking in the RAM map.
Furthermore, you're referencing custom patches in your description. ROM map addresses should only
deal with the clean ROM or something very
common (I think only Lunar Magic would count, as of now).
As a side note, I recommend that you get someone to proofread everything you submit -- it'd be nice to have a clear and consistent ROM map.
