Hacking Downgrade Mt-Card hardware

[innercy]

I attempting to downgrade my Mt-card from 2.0 to 1.4 just to try whether lower hardware will work in new software, however i can't seem to downgrade.

Is it even possible?.

it is if you load it with older launcher.dat. It will ask to "update" which would downgrade it.
