| The levels can't be compressed into 21 bytes. It is just not possible to store than amount of information that way. My guess is that it's just the level headers. Perhaps you need to check the beginning of the ROM for the actual data. I know that some games, level data is stored from the very first offset. | |||

| Hmm, looks like Sapros is pretty buggy, even when I restore a ROM it curropts the old area again when I try to curropt other areas, can anyone recommend any curropter? | |||

 OK, I figured out the level data format. It's really easy, but please forgive any errors or wacky grammar, as it's really, really late.  Also note that this data only applies to Niagara Falls; I haven't found the pointers to the other levels yet, though everything's stored within the same bank.Level header: $10010, the second two bytes point to the "screen order table," the rest are probably related to the block mappings (See Coby's post). Everything from $10012-$10025 is copied to $4B-$5E in RAM. Level layout: The first screen (01) of Niagara Falls starts at $11D5A (note: this is NOT the first screen you start on, that's actually at $120DA). Each screen is comprised of 64 (8 rows x 8 columns) 4x4-tile blocks, similar (IIRC) to Castlevania. The first row is completely obscured by the status bar, the second row is half-visible, and the last row is just barely visible at the bottom of the screen (only 1 row of tiles is shown). Each screen's blocks are stored sequentially, starting from the top-left corner of the screen and ending at the bottom-right corner, running left to right. There is no break between each room's data, and there is no compression. The "screen order table" starts at $11C3A. Niagara Falls is 8 screens wide x 6 screens tall (this is probably defined in the level header). Each individual screen is assigned a number from 01 to 1F, and this table determines which screen will be loaded where. A visual aid should be more helpful (0F is the starting position, and 0D is the boss room):  This table also defines the level's scrolling boundaries; a value of 00 will stop horizontal scrolling in the current direction. The edges of the level are treated as 00s as well. I believe there is another table of some kind, separate from the screen order table, that affects how the status bar is handled during vertical scrolling; adding a vertical scroll where there wasn't one before will mess up the status bar (but nothing else). Should be relatively simple to figure out. (edited by BMF54123 on 01-31-05 01:30 PM) |

Originally posted by Coby Yeah, the restore ROM function doesn't reload the ROM in the memory of Sapros. A stupid logic bug. That's been fixed now.  |

BMF: Woah :o Now, how did you find that? :O Because now I didn't really learn a lot :o But still thanks!  Dan: Oh so there's a new version? Your site showed 0.1.1 as the latest version and that's also the version I seem to be having. Oh well. *Coby redownloads |

Originally posted by BMF54123 There is 2 tables if I remember right...the 21 byte table should be for layout of each screen in chuncks of blocks or something and then there is another table which will have TSA in it. It confused me after awhile that is why I discontinued MWOD which was going to edit this game. |
