Right. BTW, most of DOS speeders (SPEEDOS, PROLOGIC DOS, JIFFY DOS?) fixes that bug.
I also fixed it in my KERNAL patch (if someone would need, the source available).
Although Action Replay does not (!). Can anyone confirm other freezers (eg. FINAL 3,
Magic Formel, Super Snapshot) by trying list the '1 REM CTRL+L' line.

Because the BSOUT ($FFD2) checks the STOP flag which returns C=1 if pressed. Then in
$E107 'BREAK' message displayed if STOP pressed.
