Adapter seems to be working great, tried out some more games over the weekend and I'm loving it so far. I was also able to map the table of hotkey combos (updated above), except the "Input State Slot Increase/Decrease" triggers at the same time that I go to Save or Load which is mapped to D-Pad right/left.

All retroarch.cfg:

input_state_slot_increase = "right" input_state_slot_decrease = "left"

N64 retroarch.cfg:

input_state_slot_decrease = "nul" input_state_slot_decrease_axis = "-3" input_state_slot_decrease_btn = "nul" input_state_slot_decrease_mbtn = "nul" input_state_slot_increase = "nul" input_state_slot_increase_axis = "+3" input_state_slot_increase_btn = "nul" input_state_slot_increase_mbtn = "nul"

-3 and +3 are C-Button left and right. If I set the All config to "nul", they won't work in any other emulator, correct? Should -3 and +3 be mapped to input_state_slot_increase/decrease instead of the ones with "_axis"?
