I will check asap. But i have succefully managed to map the restore key with f10 button in my c64 emul (winvice 2.4, windows7) by changing the vkm file. Had the same problem with restore key (pgup).

Have you managed to “kill yourself” in main game (castles of dr creep)?

Edit: i checked. Nothing works. When i hit esc the game pauses. I use keyset with arrow keys+left ctrl for fire. I dont use gamepad. I also cannot go into MAP screen..
