Q: Can I get a different mapping?
A: Unfortunately different mappings are not possible on this adapter since it is a simple wire-to-wire design without a micro-controller. This not very flexible, but it provides "speed of light" latency (i.e. zero).

Q: But if it's just wiring, can't you just swap wires to remap buttons?
A: No. NES and SNES controllers use a serial protocol. i.e. Button states (bits) are sent by the controller in a specific (and fixed) sequence over a single wire. We would need to introduce a micro-controller in the middle to reorder the bits, and this would mean a completely different design. There are not plans to make one currently.

[1] Ignoring of course the speed of electricity in the extra 5ft of cable. Assuming a velocity factor of 42% the speed of light, this means a latency of about 24ns (0.0000000240 second). Of course it does not matter at all.
