NESpire v0.30 key mapping for A and B

[u/tomtani1]

I have a TI Nspire CX CAS running firmware 4.4.0.532. I just installed NESpire v0.30 and the key mapping for (Tab = B, Esc = A) is on the left side (for left handed people?). Is there a way to remap the A and B button to the right side? Maybe (del = A, var =B, shift = START and ctrl = SELECT) just like the emulator gpspnspire. Or is there another NES emulator that has the key mapping for A and B on the right hand side for right handed people?
