The baserom remaps a bunch of sprites and shuffles some graphics around to fit in some useful sprite and block resources. Below is a breakdown of all of the graphical modifications made to the Vanilla game, if you are interested in seeing what those changes are or want to revert them.

Edited Graphics

The following is a breakdown of modifications to original graphics files. Originals can be found in the resources/original_graphics folder.

GFX00 : Global Sprite Graphics (SP1)*

• The 8x8 tiles for Mario have been removed as they are now dynamically inserted using the "Mario 8x8 DMA-er" patch.
• Tiles for the bounce sprites for the ON/OFF and Note blocks have been moved here.
• A splash frame has been patched to turn it into three 8x8 tiles, the 4th freed up tile is being used by the retry indicator graphic.
• 8x8 tiles for lava/podobo splashes, Yoshi's tongue and throat have been moved here.
• A frame for the blue sliding koopa has been moved to GFX01.
• Space was reserved for dynamic retry tiles and the Mario 8x8 DMA-er.

GFX01 : Global Sprite Graphics (SP2)*

• Graphic for the donut block sprite replaces the Coin Game Cloud coin tile. Coin Game Cloud has been remapped to use the other sprite coin tile.
• Flopping fish tiles were moved to GFX13.
• Tile for Piranha plant stem was added here, replacing a flopping fish tile.
• A frame for the blue sliding koopa from GFX00 was added here.
• Tile for an "ejected" blue koopa has been remapped and Poison Mushroom was added in its place.

GFX08 : Switch Palace (FG3)

• Sunken ship tiles were moved to GFX1E.
• Additional corner tiles for Switch palace foreground were added.

GFX13 : Sprite Tiles (SP3)*

• Note block bounce sprite frame moved to GFX00.
• Tiles for the flopping fish from GFX01 were added here and the fish was rearranged.
• A frame of the hammer has been moved.
• 8x8 tiles for the small note and egg fragment have been moved.

GFX14 : Global Foreground Tiles (FG1)

• Some unused tiles have been replaced with sideways cloud graphics and vertical rope. The turnblock is now a destination for one-ways ExAnimation .

GFX16 : Rope Foreground (FG3)

• Tiles for the mushroom platform were shifted so a proper rope corner could be added.

GFX17 : Global Foreground Tiles (FG2)

• A duplicate tile in the door and the unused pressed P-switch tile were replaced with vine ends.

GFX1E : Overworld (FG4)

• The half sunken ship was moved into blank tile space from GFX08.

GFX29 : Layer 3 tiles (LG2)

• The tile for the "©" symbol from the title screen has been moved to GFX2A to make room for the Layer 3 status bar retry indicator.

GFX2A : Layer 3 tiles (LG3)

• The unused graphics for "AND" have been removed, and part of "Nintendo" and the "©" symbol from the title screen has been moved here from GFX2B.

GFX2B : Layer 3 tiles (LG4)

• The unused graphics for "Super Mario Bros. 4" have been replaced with "Romhack Races Baserom" tiles.
• Part of "Nintendo" has been moved to GFX2A, and an "8" and "9" tile has been added to make it usable when typing those numbers into info messages.

GFX33 : Global Animation Tiles

• The midway animation frames have been fixed.
• Always turning block animation was lightly edited.
• The castle conveyor/stairs have been fixed to use the the castle's brick pattern.

Remapped Graphics

In resources that formerly contained tiles for remapped sprites (namely the lava splash tiles, Yoshi tongue tiles, and the ON/OFF bounce sprite tiles) there will be placeholder graphics in the freed-up space.

GFX03 GFX04 GFX05 GFX06 GFX0D GFX0E

Unedited versions of these resources can be found in the resources/original_graphics folder.

ExGraphics

ExGFXB54: ExGraphic Version of Big Bush and Pipe (BG2)

• Contains optional tiles for the big bushes and big pipe that can be used as ExGraphics, as well as some alternative pipe corner tiles.
• Must be loaded into slot BG2, and their Map16 Files are found in resources/map16. See demo level for example.

ExGFXE17: Custom Global Block Tiles (FG2)

• Contains all tiles for custom global blocks that use ExGraphics and the global line guide and screen scrolling pipe tiles.
• This resource is arranged to be drop in replacement for GFX17 (FG2) as the custom blocks use tiles normally used for the Big Bush and Large Slanted Pipe objects.

ExGFXFF: Font (BG3)

• A basic 8x8 font and symbol set for in-level text, used in the Demo level.

Alternate ExGraphics

Lunar Magic supports a special sort of ExGraphic called "Alternate ExGFX" which is used for ExAnimation to store frames that are globally available in the ROM (opposed to slot AN2, which is per-level). The baserom stores some frame data to ExGFX61.

ExGFX61: Global ExAnimation

In the baserom the ExGFX61 resource contains all global animation frames, for ON/OFF tiles, one-Ways, the sprite note block, etc. See the Exanimation page for more details on how they're used. However there are some extra frames available for additional use.

Palettes

Poison Mushroom

The Poison mushroom is the only sprite in the baserom using a custom palette–palette row A for the hurt mushroom and row B for the kill variety–you can import it from resources/palettes/PoisonMushroom.pal to use in your level(s).

Custom Blocks

Some of the global custom block graphics (one-ways, death blocks, etc.) use palette row 7 for their graphics. If you need to use it in your level(s) you can import resources/palettes/CustomBlocks.pal.

Mario's 8x8 Graphics

The baserom uses the Mario's 8x8 Tiles DMA-er patch to upload all of Mario's 8x8 tiles directly to memory (DMA), freeing up significant space in GFX00, which the baserom uses to have some tiles remapped into the global sprites space (see above).

What this means for building a hack is that, if you want to change the player graphics, you will have to update or replace the graphic resource this patch uses to dynamically upload Mario's tiles. You can find them in: resources/patches/other/ExtendGFX.bin.
