ok last night i download the divice with all the stuff i wanted in it
the file i saw in saved game folder
i tryed to load it during LCS but it said "can not load, data corrupt''

what do i do?

There are 3 possible reasons for this.

1. You're on a firmware which doesn't support the save game cheat device. (2.60 is the highest from the normal one, 3.03 for the special one you can find on qj.net)
2. You have a patched version of LCS, in which case your only chance of running a cheat device is by using the prx one (requires a custom firmware or devhook)
3. You might have put the cheat device on the ms in a wrong way, not unpacked the .zip for example. However I thihnk one of the 2 first is more likely.
