Indeed, previously loaded ROM is not wiped out of memory but simply overwritten 
by next loaded ROM so if that previous ROM was larger than current one, it 
still exists in upper memory area.

For most games, it does not matter since ROM is mirrored and only currently 
loaded ROM data is accessible.

However, for S&K, upper part above S&K ROM is not mirrored and accessible since 
it is reserved to cartridge lock-on area, so if a valid game header was loaded 
in that area (which is the case with Sonic xx & Knuckles combined ROMs), S&K 
will see it on startup and assume there is a locked cartridge.

I Didn't see this in the issues list so I though I'd let you know if you didn't 
already.

Also thanks for the great work/port by the way.
