So it seems there are certain commands that key off of the the hotkey when it is enabled in retroarch.cfg. If you disable hotkeys you can map those commands to specific buttons, so you do not need a combo of 2 buttons to issue those commands.
1. I wish there was a list somewhere of all the commands that turn into hotkey combos when hotkeys are enabled.
2. I wish there was a way you could have selective hotkeys, where you can decide whether a command from the hotkey command list is activated by a hotkey combo button press or by a single non-hotkeyed button.
You could mix and match if you were able to define your hotkey commands, like in a config file or something where you could list which commands are subject to a hotkey. Maybe it could be a new command called magickey and you could define several magic keys (magickey1_btn=”9″, magickey2_btn=”8″) and magickey lists (lists of commands available when a particular magickey is pressed). By the way, I think that video is old, I don’t see the hotkey.sh because the directory from the video doesn’t exist.
No, sorry I meant the hotkey.sh file is there on 2.4.x
Although I think all the keys are listed in retroarch.cfg, the only ones I tend to use are the shaders and saving and loading games along with exit emulator. Lots of options show in the RGUI as well with F1.
