Games	Fury of the Furries Pac-In-Time

Fury of the Furries gamedat.bin files contain save-points and preferences.

The file consists of 10 2-byte values. Each is hidden by an XOR bitmask and a logical shift.

To decode a byte, xor it with 0xE9 and apply a 'shift left with bit rotation' twice. To encode a byte, apply a 'shift right with bit rotation' twice and then xor it with 0xE9

Format

Data type	Name	Description

Source code example in C:

void decode(unsigned char *gameDat) {
  for (unsigned int i = 0; i < 20; i++) {
    gameDat[i] ^= 0xE9;
    gameDat[i] = (gameDat[i] << 2) | (gameDat[i] >> 6); 
  }
}

void encode(unsigned char *gameDat) {
  for (unsigned int i = 0; i < 20; i++) {
    gameDat[i] = (gameDat[i] >> 2) | (gameDat[i] << 6);
    gameDat[i] ^= 0xE9;
  }
}
