Drastic / NDS fix pen on L2

- TSP L2 and R2 are analog triggers in reality so it can be configured in push (JS0 Axis -) or release mode (JS0 Axis +), it was necessary to invert it. (otherwise some games like Chrono Trigger have the pen always touching)
- Disable frameskip by default as it is not necessary and has impact on fluidity
