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. EDIT: Looks like I found something else, too. The Title screen is stored in 0x159E0 - 0x15C1F. EDIT 2: And the "Choose a File" level is stored in 0x30A52 - 0x30C91. EDIT 3: The HUD at the bottom of the screen is located in 0x7EA - 0x7FD. EDIT 4: And the Coin Wall is located at 0x32492 - 0x326D1. EDIT 5: Gathered some notes: Graphics locations 0x141E5 - 0x159E4 | Title Graphics 0x18000 - 0x197FF | Mario 0x19800 - 0x1AD7F | Tree Zone enemies and Boss 0x1C000 - 0x1F84F | Level tiles 0x30C92 - 0x31491 | Coin Wall sprites 0x31492 - 0x32491 | Coin Wall tiles 0x32ACA - 0x32E49 | File selection sprites 0x34000 - 0x347FF | Overworld sprites 0x34800 - 0x357FF | Overworld tiles 0x35800 - 0x35FFF | Macro Zone sprites..? 0x36000 - 0x36FFF | Macro Zone tiles 0x38000 - 0x384FF | Pumpkin Zone sprites 0x38500 - 0x387FF | Pumpkin Zone Tileset (only used after completion) 0x38800 - 0x397FF | Pumpkin Zone Tileset (includes also the Minigame Hill Tileset) 0x39800 - 0x39FFF | Tree Zone sprites 0x3A000 - 0x3AFFF | Tree Zone tiles 0x40000 - 0x407FF | Space Zone sprites 0x40800 - 0x417FF | Space Zone tiles 0x41800 - 0x41FFF | Mario Zone objects and some Mario's Castle sprites 0x42000 - 0x42FFF | Mario's Castle Tileset 0x44000 - 0x447FF | Mario Zone sprites 0x44800 - 0x457FF | Mario Zone tiles 0x45800 - 0x45FFF | Wario's Castle sprites 0x46000 - 0x46FFF | Wario's Castle tiles 0x64000 - 0x64FFF | Converyor game graphics 0x65000 - 0x65FFF | Rat game graphics 0x68656 - 0x68E55 | Ending graphics 0x6C000 - 0x6DDFF | Mario Zone level tiles 0x6DE00 - 0x6EFFF | Mario Zone enemies and Boss 0x6F000 - 0x6FBFF | HUD tiles 0x70000 - 0x71DFF | Macro Zone level tiles 0x71E00 - 0x72FFF | Macro Zone enemies and Boss 0x74000 - 0x757FF | Turtle Zone level tiles 0x75800 - 0x7667F | Turtle Zone enemies and Boss 0x76680 - 0x77E7F | Animated tiles 0x78000 - 0x78BFF | Space Zone level tiles 0x78C00 - 0x799FF | Wario's Castle level tiles 0x79A00 - 0x7A36F | Hippo Zone enemies and some Space Zone enemies 0x7A370 - 0x7A87F | Space Zone Boss 0x7A880 - 0x7B67F | Wario's Castle enemies and Boss 0x7C000 - 0x7DDFF | Pumpkin Zone level tiles 0x7DE00 - 0x6EFFF | Pumpking Zone enemies and Boss So how about some new MarCas now? 
EDIT: There are some flaws in my notes. Please contact me if you are up to hacking SML2. ____________________ |
