This may be old news, but I figured I'd post it for anyone that didn't know about it.
Softcoding is stored in the eeprom. Follows the same format as the login (skc) code. Take the locations at 7a and 7b (mirrored below, 8a and 8b), byteswap them, and convert to decimal. Example:
D319=19D3
Converted to decimal=6611 (m-box softcoding)
What thread is complete without pictures!
Daz very good info, but have a doubt, do you need to correct checksumm manually if we change SoftCoding in dump?
