RAM address data
Length	2
Type	uint16
Name
Description	Reset check 1

If all 4 reset check addresses are set to certain values on startup, then the RAM area [$7E:2000-$7E:2128) will not be cleared, so that the high scores are preserved when the console is reset. These addresses are set to these certain values later in the startup routine and never changed, so they will be the same as long as the power is kept on.
