After running the update my high scores now save ok.
Im stilll have no luck changing the hotkey from "num6" to "h"
If I edit it with notpad++ it looks right but no changes to how it functions.
Also ive tried to change in ES controller config. When I get to the hotkey input at the end- I press my new button and get a key h input from the ipac2... still doesn't seem to actually change the hot key.
I have game and core remap files for tons of games if this matters. Can anyone help me?
I've just done this with an ipac2.
You can configure player 2 in the retro arch menu (vids on you tube)
When entering the player 2 button key binds ...Check the order compared to player 1. Strong chance it will not be what you think.
Once you have done that you can quickly map your button inputs and save.
Problem is this. 3rd Party images are not supported. You should ask MLP as nobody can predict the setup. Also, https://retropie.org.uk/forum/topic/3/read-this-first - you dont even say what version of Mame? Reimage, post details of your setup and help becomes possible.
