| Ok the structs are taken directly out of my editor so yeah
Some of the stuff may be hard to understand so yeah These notes were based off the original findings from Jigglysaint I then took what I learn and finished the rest of the stuff. More to come next update finished door notes and add item notes Data room size = 0x3c Room Headers start at: 0x340AD4 Total number of rooms: 329 Pointer table for it at 0xNONE Pointer table for Tileset entries 0x33DFDC I'll just load these according the rooms Tileset number  And uncompress on the
fly! =D Structure for Room Headers Private Type RHeader bTileSet As Byte bBg0 As Byte bBg1 As Byte bBg2 As Byte lBg3 As Long lForeground As Long lLevelData As Long lBackGroundObjects As Long lClipData As Long lBackgroundImageData As Long bEnemyIndex As Byte bSwitch As Byte bSeperator1 As Byte bSeperator2 As Byte lEnemy1 As Long bEnemy1Sprites As Byte bDunno1 As Byte bSeperator3 As Byte bSeperator4 As Byte lEnemy2Sprites As Long notsure As Long TileTablepnt As Long bSeperator5 As Byte bMiniMapRoomX As Byte bMiniMapRoomY As Byte bSeperator6 As Byte bTide As Byte bEffect As Byte bMusic As Integer End Type Private Type gTileData Nothing As Long gTiles As Long pTiles As Long BackgroundTSA As Long MainTSA As Long End Type Applies to lForeground ************************************************************************************************************************* | Ok I'm not that that this stuff is compressed | | Anyhow Width times Height bytes of course then that random 01 | | Next are These 2 bytes no clue what they are for although if I edit them it really messes up | | Ok After that is a what I believe a byte that controls the X and Y position by moving the Block to the right and down | | The higher the byte control byte the lower and to the right it goes | ************************************************************************************************************************| Applies to lTilesPnt, And lClipdata; ***************************************************************************************** |Level compression is RLE 2 different types Why I have no clue | |Any how the compressions are like this | | | |if the first byte is 0x00 - 0x7F Then the game repeats the next byte that many times | |The other type of compression is 0x80+ folled by the tile/clip | |The way it works is subtract 0x80 from the first number then repeat that | |the tile that many times oh and by tile I mean the ID | ***************************************************************************************** Applies to lBackgroundObjects ***************************************************************************************** Door data: 0x33E614 I'm guessing the struct is 0x8 bytes struct Door{ char SomeByte; char Room//? char DoorCanOpen; char DoorLeadssomeplace; char Dunno; char Dunno; char Room;//Actual Room! }; MiniMap Areas: lz77 compressed 407178 4072e4 4074ac 4077b4 Spritesheet List: Tested in Room Header 4 Test em in different rooms for fun effects 00 Bubbly 01 Elevator 02 Skrees.
