Just want to share that I have received a bugfix from Jeff (NeoBitz) which prevents loading the title screen twice if the game loop is finished
but still credits available (will cause a screen flicker, like shown at minute 2:18 in the third video). To fix this issue you need to add a
BIOS_COMPULSION_FLAG at the start of the "Title Mode":
volMEMBYTE(0x10FEC5)=0x01; // BIOS_COMPULSION_FLAG
