Hey so im using retrpoie 4.6 pi4
and i did that with dosboxpure -

"Start menu with auto start- 
This is the first screen that appears when loading a game. It offers a gamepad controllable list of all executable files for the loaded game. By pressing right an item can be selected as the default which will skip the menu on the next launch.
By pressing right multiple times, a number of frames can be specified that will automatically be skipped on start. This can be used to skip over loading screens or start-up sequences.
If there is only a single executable, the menu will not show and directly run the file.
To force the menu to be shown, hold shift on the keyboard or L2 or R2 on the gamepad while selecting Restart in the core menu."

So now i have a default exe file by mistake and i cant go back to the first menu to pick a file.
I did try whats it saying with L2+R2 or shift and rest...
but didnt work for me .
Anyone try that ?
thanks
