FBNeo vertical games not working with RGBPi2

[squidrpi]

Describe the bug
same as #95
With RGBPI2 the vertical mode for vertical games is the correct rotation using "Vertical Mode: DISABLED" but the screen is stretched horizontally and no way to set "Aspect Ratio: Full scrn native" which is greyed out with the RGBPI2. On non-RGBPi2 hardware "Aspect Ratio:" is available to be set.

Setup:

• Device: Pi500 RGBPi2
• OS version: 1.3

It is not the same issue but anyhow I've already reworked all the code and options related to TATE games for the next version so you'll see many changes and fixes.
