Lower Screen

The vertical screen is 800 pixels high causing 640 to be centered.
It would be better to move screen down so we can see from bottom up.

10. P2 Start for Back Command
11. P2 Start for Back Command
12. P2 Start for Back Command
13. Select Quick Menu
14. Select Overrides

RA Content Directory Override

1. \\DonkeyKong\configs\all\retroarch\config\FinalBurn Neo\fba.cfg
2. FinalBurn Neo is the name of the core
3. fba is the title of the directory
4. This means Content Directory Overrides are not directory location based.
5. Content Directory Overrides are directory title based.
6. Content Directory Overrides are directory title based.
7. This should only impact \\DonkeyKong\roms\am\fba
