x68000 keys in lr-px68k

insx

Hi Folks

I think I can use Game Focus to use a keyboard but is there any way to input the Opt 1 key on a standard PC keyboard with the lr-px68k core?

My aim is to hold Opt 1 and enter "sybubblun" on the keyboard.

I'm using a Pi 4 with Retropie 4.8.6, two Dragonrise controllers and a USB keyboard.

Scroll-lock is the default key for game-focus.
I am guessing :
You want to use Game-Focus but you have a reduced keyboard without numpad and scroll-lock key, right ?

You can set the Game Focus inside the retroarch.cfg :

input_auto_game_focus = "2"
input_game_focus_toggle = "ralt"

First line will bring the core in game-focus by default and the second line will use Right-Alt for toggling between game-focus.
Right-Alt should be the same as the option key.
Alternatively you use the second line only if you want.

If you want to enable just for lr-px68k then add it to :
/opt/retropie/configs/x68000/retroach.cfg
Otherwise, if you want to add it for all cores then add it in :
/opt/retropie/configs/all/retroach.cfg

I have a full keyboard and no problem toggling game focus but I couldn't figure out if there was a key that sends Opt 1 and there doesn't seem to be a way to define input for special x68000 keys like there is in MAME 0.255.

Ok, I saw the original keyboard layout of the x68000.
I think I know what you mean, using the "Opt 1" key.
Seems that in the keyboard section of the libretro docs the "Opt 1" key is missing.
Libretro cores mostly focus on running games and not on emulating keyboard perfectly.
So you are probably out of luck.
I tried some things but I also failed, so I can't be of more help.

You may try the standalone px68k emulator and configure a keyconf.dat to map the key to something on an EN-US keyboard. The key code for OPT1 is 0x7 (see here). You may even do this temporary - if there's a game that supports saves on a user/floppy disk you can then re-use the disk with the game started on the libretro core.
