UPDATE : 1.1
-To jump to desired "list" at launch, just create an empty file called:
TLGECS,TLGAGA,TLDECS or TLDAGA in /s directory.
-You can now return to the "Space Invader" screen from a list:
At the 1st item in the list, hold "up"+"fire"
-Keyboard is now supported. Use the arrows to navigate, enter to select, (ESC or BACKSPACE) to go back, H for help.
Edit : Tested on CD32+SX1 and Amiga 500 1MB (No whdload) : both work ok.
