Sorry, if this has been discussed before (I could find only a few slightly related discussions but that probably doesn't mean a thing), but is there the slightest chance of implementing something like a "Carousel Core" that can be used for e.g. an arcade machine aimed at the dummy user who just want to select a game from a cool looking screenshot and some description text by basic joystick controls (left/right/button)?
Obviously, MiSTer is totally awesome and all, but selecting hundreds of NeoGeo and Arcade games from the normal menu is a bit underwhelming and definitely not something for the dummy user. And yes, MGL might be a step in the right direction, but IMHO it's not a big step.
I wished there was some possibility to have an alternative (configurable) user interface that looked more like the Carousel of all that SW-Emulation based "Pandora's Box" Arcade things, the "Neogeo Arcade Stick Pro" or the "TheA500 Mini". If the Cortex CPU/Linux System doesn't have the power for this, I wonder if it would be possible to create a core that handles displaying Carousel/Menu and that would leave the information what to start to the Linux system which then would launch the according core or rom (etc.) within the core.
