Keyboard does not work with MAME 2003 Plus

[yokomaka]

Hello everyone,

For some reason my USB keyboard does not work in any game if I use the MAME 2003 Plus core. USB gamepads work without problem.

The keyboard works fine I use any other cores (i.e. plain MAME 2003). All settings are on default. Has anyone else experienced this behaviour?

I'm running Recalbox 6.1.1 on Raspi 3b+.
