Bluemsx - we lost keys mapping testing future pi3b currently in beta testing

[JOBARE]

Hi folks.

Since the recalbox 4.1, BlueMsx core had been patched to map F1/F2/F5 keys on the first gamepad.

It seems that we lost keys mapping testing future pib3 version that is still in beta testing.
(BlueMsx and keys mapping was ok testing 18.04.20 release)

I tested applying following commits as indicated on website site dedicated to betas tests for next Pi3b version (https://forum.recalbox.com/topic/15010/testers-wanted-major-system-upgrade-pi3b-kodi-17-and-much-more) :

1st update (fix): https://review-master-slwsz0-archive-review-prod.recalbox.com
2nd update (master of Pi3b release) : https://review-507-b*mp-b-0jn0c0-archive-review-prod.recalbox.com

We still have the problem even applying successively the two commits.

Could you please have a look before releasing stable version ?..

Thank's for your good work.
