I'm currently working on a raspberry pi project for game emulation with a colleague, which we intend on selling on a small scale.
We are looking around for an OS to use, which has a commercial license. We would love to use RetroPie, and we have been given permission from them to use their setup script, however, RetroPie is a collaboration of several different projects put together. We would need permisson from the individual driver and emulator owners to use it commerically.
If anyone has any suggestions or ideas, they would be much appreciated.
