Title: (BlackBerry) Get input overlay to show when booting to RGUI

You still need to hard code the overlay path in retroarch.cfg. This should let you choose a core, a rom and boot it up. The overlay covers parts of RGUI which makes it hard to navigate sometimes. Might have to change the aspect ratio or width.
