Joy2Key.py?

@moosepr said in Joy2Key.py?:
I'm assuming that runcommand is still active because it triggers the emulator, so won't close until the emulator does
The runcommand script should remain active throughout your gaming session. However,
joy2key.py
is supposed to exit alongside the Runcommand menu. Just to be completely clear, is this not the case for you? -
@mediamogul that is what happens. i always assumed runcommand was just a quick run job before the emulator starts, but it makes more sense that its actually triggering the emulator too.
are all the emulators normalised then, to use the same keys as input, or does the Joy2Key run differently for each emulator?

No, as @mediamogul said,
joy2key
is not used by any emulators, just by Runcommand (and the RetroPie-Setup menu, when started from ES). -
@mitu The joy2key seems so confusing to many users. A hint in the wiki may be usefull. For what it is and what it does
@moosepr You can see the work of the joy2key in the Midnight Joy [SCRIPTLET]. This script will run MidnightCommander (a file manager for shell) and assign some keyboard keys to joy2key so you can do file actions with your controller.
Otherwise you need a SSH or keyboard connection to control this tool. -
@mitu ah i missunderstood.
So Joy2Key is not needed for the emulator, just for the runcommand menu? If this is the case, then it is sat in the background using cpu when it doesnt need to be

It's only active for the duration of the Runcommand window. After the Runcommand window exits, so does
joy2key.py
. That being the case, it's never really wasting any CPU time. -
@mediamogul but if runcommand triggers the emulator, then it is running for the duration of the emulation session. or at least that is what i saw in my experimentation

@moosepr Please add more info about your system - https://retropie.org.uk/forum/topic/3/read-this-first. If you stop your uinput script, does
joy2key
still remain resident ? -
@mitu I will test when i get home
The setup is a Raspberry Pi zero, running the latest Retropie. There is a tft driver (https://github.com/juj/fbcp-ili9341) my own bespoke uinput code emulating a controller and monitoring battery voltage, and running dtoverlay=hifiberry-dac and dtoverlay=i2s-mmap
-
ok so further testing. If i use adafruit retrogame, i see Joy2key appear in Top at about 20% cpu, then after a few seconds it disappears.
Using my own code, Joy2key does the same 20% ish cpu for a few seconds, then it will sit at about 4% cup for as long as im playing a game. it actually remains even when i close the emulator (start + select)
