yep, that´s expected for most games, maybe you should read in user manual what this option is supposed to do and what it is for...
there was a reason for part of the screen to be hidden by Game Gear LCD, you just discover it.

btw, if someone is thinking of a better name for this option, because i am sure you will not be the last one complaining about screen garbage in this mode, he is welcome...

Perhaps just showing a warning message the first time that option is turned on would do?

Something like "Warning: Please note that some games will show scrambled graphics that were intended to be kept hidden behind the borders".
