hi,
this CMD come out from packets the xbox sends out.
All system link use the same, and are generated by the M$ API.
Not exactly ALL, because some all game don't have this "ping limit", but use the same API.
I see now two possible solutions:
- Found in the nand the key used to encrypt the daya after 0x34 and than fake a echo-reply (the best because no need to have a hacked xbox).
- compare the API call in this old game and a new one. Than modify the XEX to disable this "ping test".
Ledjohnnyboy , you have make a good search, if you found now the call to this API, for sure you can disable this limit.
