Wrestling Empire Save: Bytes

At offset 0x04, a simple XOR checksum of all bytes from 0x08 to end-of-file.
If the checksum fails, the game treats the save as corrupted and may reset it.

checksum = 0
for each byte in data[0x08:EOF]:
    checksum ^= byte
save[0x04] = checksum & 0xFF

If you have multiple career slots (e.g., "Career 1," "Career 2," "Sandbox"), delete the oldest one. The game loads ALL career data into memory, not just the active one.

Go to Edit Mode → Edit Parts. Delete any custom logos, tattoo designs, or attire pieces you created on a whim and never used. Each deleted part returns precious bytes.

with open("career.bin", "r+b") as f:
    data = bytearray(f.read())
    # Set wrestler 1 (offset 2) age to 25
    data[2] = 25
    # Set wrestler 1 morale to 100
    data[3] = 100
    f.seek(0)
    f.write(data)
