The "player input" for the Word Rescue demos is stored in the WR?.D* files. Each level has its own demo file.
The demo files are can be up to 4000 bytes in size and each byte stores the player input for 1 game cycle/frame. The bits in each byte have the following meaning:
| Bit | Mask | Description |
|---|---|---|
| 7 | 0x80 | unused |
| 6 | 0x40 | unused |
| 5 | 0x20 | end of demo marker |
| 4 | 0x10 | slime |
| 3 | 0x08 | left |
| 2 | 0x04 | right |
| 1 | 0x02 | climb down |
| 0 | 0x01 | jump / climb up |
Math Rescue
Math Rescue uses the same basic format with some minor changes.
- The file names are MR?.D*
- The demo files are limited to a maximum size of only 3000 bytes.
- The game does not allow each level to have its own demo file. The levels for which the game expects to find demo files are hard-coded.
- Aside from the regular player input, Math Rescue also stores the "random" numbers for the math puzzles in the demo stream. There is no way to tell if a bytes is user input or a random number. The game detects this by context (when the player touches a number icon).
