Please check before continuing:

• I've searched my issue or question to make sure it has not been reported/answered already
• I've checked COMPATIBILITY.md to make sure my emulator or system is known to work
• I understand there is no physical release and you are not responsible for issues with bootlegs
• This is a bug or question and not a feature request

This might technically be considered a feature request rather than a bug since nothing is technically going wrong in the current code, but it is an inaccuracy relative to the original game. Feel free to close if you feel this doesn't warrant fixing.

In the many single screen height areas like Arthur's House and the Egg Corridor, the original game uses a fixed camera height, never scrolling vertically, but scrolling horizontally if necessary. This port scrolls those areas vertically to accommodate the reduced resolution of the NTSC Genesis, but they still scroll on PAL Mega Drive, where the resolution is identical to the original PC game and no scrolling is necessary.

I know the Egg Corridor is technically larger than 240 lines, so checking if an area is ≤ SCREEN_HEIGHT would still result in scrolling in situations like that. Perhaps ≤ (SCREEN_HEIGHT + 16) or something?

Apologies if this behavior has changed since the last stable. I'm testing via 0.6.0, as the version from #324 crashes the emulator (Genesis Plus GX via RetroArch on Wii U) before it reaches the title screen on my end.
