lr-vice configuration problems

[j.e.f.f]

Hello

I've been configuring C-64 games to run on my set up. I'm using lr-vice for all my games. I'm just about 99% of the way there, but I've run into two issues that I can't seem to crack:

1. The ENTER key on my keyboard is mapped to the FIRE button on joyport 1. So any game that involves entering text, say Ghostbusters, I need to press RETURN at the end of it, but it obviously doesn't work. I can't seem to find where to unmap the keyboard keys. I can find where to remap gamepad controls, in fact I'm working around this now by mapping RETURN to a button on the game pad, but ideally I'd like the keyboard to work as normal.

2. The virtual keyboard in lr-vice doesn't seem to actually work. I can raise the keyboard, navigate it with the game pad, and when I press A on the game pad the corresponding virtual key briefly flashes reflecting that it's been "pressed." but no keypress is registered in lr-vice. Has anyone else noticed this?

This is on a Pi 3B+, no overclock. 2.5A/5.1V Canakit power supply.

@j-e-f-f I've never used the libretro one but for the standard vice I had to change the keyboard from symbolic to positional, not sure if that will help in your case as I don't recall having your issue but my other issues were solved with this change.
