C button and Start button tied together (Pico Drive)

[GreencapGonzo]

Issue found on Pico Drive version 0.94 for the O3DS custom firmware Luma3DS 10.2.1
Regardless of how buttons are mapped, whatever button is mapped to C is also mapped to Start. I genuinely have no more information than this. If you would like more information, please contact me.
[edit]
This is apparently a problem with pico drive itself for certain games (such as DeCap Attack)
I don't know what can be done about it or if it has been fixed in the mean time

This issue is not really a bug with the emulator but due to an weird way decapattack game handles the controller buttons. Nevertheless, the original picodrive code maintainer has provided a "hack" for it which I confirm it works on the picodrive_3ds. I have submitted a pull request. #38
