Yeah. Thought I'd make my contribution to the hacking community, so here's the SML2 Overworld format, oven-fresh. Have a great time hacking. 
The main overworld is built from Chunks. One Chunk is 1024 bytes, and is composed from 32 rows, each containing 32 bytes. One byte is one tile. 0x37000 - 0x373FF | Chunk 1 0x37400 - 0x377FF | Chunk 2 0x37800 - 0x37BFF | Chunk 3 0x37C00 - 0x37FFF | Chunk 4 For extra reference, please see this. Besides the main overworld, there are the submaps. Submaps are stored like chunks, but there are only 20 rows, each one having 32 tiles but only 20 shown onscreen, since the submaps never involve scrolling. (Again, for extra reference, please see this.) The submaps are stored in locations listed below. 0x3B000 - 0x3B23F | Pumpkin Zone 0x3B240 - 0x2B47F | Tree Zone 0x3B480 - 0x3B6BF | Space Zone 0x3B6C0 - 0x3B8FF | Macro Zone 0x3B900 - 0x3BB3F | Turtle Zone 0x3BB40 - 0x3BD7F | Mario Zone 0x3BD80 - 0x3BFBF | Wario's Castle 0x43000 - 0x4323F | Minigame Hill The minigames are also stored like submaps. 0x43240 - 0x4347F | The 30 Coin Game 0x43480 - 0x436BF | The 50 Coin Game 0x436C0 - 0x438FF | The 200 Coin Game 0x43900 - 0x43B3F | The 999 Coin Game 0x47800 - 0x47A3F | Conveyor Game 0x47A40 - 0x47C7F | Rat Game "But how do I know what tile is what?" All the tiles are inside tilesets. To view tilesets, you need a tile viewing program like Tile Molester or Tile Layer PRO. The tilesets are located in the locations listed below. Be sure to have canvas set to 16 x 16 tiles! 0x34800 - 0x357FF | Overworld Tileset 0x36000 - 0x36FFF | Macro Zone Tilest 0x38500 - 0x387FF | Pumpkin Zone Tileset (only used after completion) 0x38800 - 0x397FF | Pumpkin Zone Tileset (includes also the Minigame Hill Tileset) 0x3A000 - 0x3AFFF | Tree Zone Tileset 0x40800 - 0x417FF | Space Zone Tileset 0x42000 - 0x42FFF | Mario's Castle Tileset 0x44800 - 0x457FF | Mario Zone Tileset 0x46000 - 0x46FFF | Wario's Castle Tileset 0x64000 - 0x64FFF | Coin Games Tileset 0x65000 - 0x65FFF | End-of-level Bonus Game Tileset However, there's a catch. When you've chosen the tile you want to have in the overworld, you'd normally get its coordinate from the tileset (FA Being tile 11 from row 16). The thing is, rows don't start from 0, but 8. Columns are normally from 0 to F, but rows go 8, 9, A, B, C, D, E, F, 0, 1, 2, 3, 4, 5, 6, 7. It isn't all that complicated. For extra reference, please see this. So how about some new MarCas now?  |
