I have finally figured out how to modify the PiMAME Menu so that it can be navigated with only the TankStick. I also edited the advmenu-****.rc files to use the left control key to ext AdvMenu.
1. Removed the number keys as a menu item selection - since number keys are used in the TS joystick 2. Added Player 1 key to select the menu item 3. Added the TS Joystick controls to move up and down the list.
AdvMenu Menu Modification - Leave AdvMenu with another key (not escape) This mod will need to be done for all advmenu-****.rc files /home/pi/.advance/advmenu-*****.rc Find the line without quotes "event_assign esc esc"
To not use the esc key, replace the second esc. event_assign esc lcontrol To add another key, add "or" with the name of the key. event_assign esc esc or lcontrol
