This page documents MediEvil saved game data formats.
MediEvil (1998 original)
A PlayStation Memory Card data block consists of 64 frames. Each frame is 128 bytes long.[1]
Frame 0
This frame is the header for a block of PS1 saved data.
Frame 1
This frame is used to store a PS1 saved game icon:
Frames 2-3
These frames are reserved for additional images in case the icon is meant to be animated, but are unused by MediEvil.
Frames 4-34
These frames contain the actual MediEvil saved game data.
File header
The header is 12 bytes long.
Name | Offset | Length | Value | Meaning |
---|---|---|---|---|
Magic | 0x0 | 4 | 60SM | Signature for MediEvil saved game data. |
Saved games | 0x4 | 1 | 0-2 | The number of saved games. |
Saved games
The file can hold a maximum of three saved games. Each saved game is 1360 bytes long. The offsets for the saved games relative to the beginning of the entire Memory Card data block are 0x20C, 0x75C, and 0xCAC.
