I can find no easily accessible references as to exactly what "retro" games/applications are actually supported. Pretty essential information I would have thought...
Anyone knows if this works with a BeagleBone Black? They mention the Raspberry Pi as supported hardware (http://www.lakka.tv/doc/Hardware-support/), so hopefully it should run on the BeagleBone as well.
You can find Roms by doing a simple google search for the game and adding "rom". Sometimes I might even add "download". You can also find rom packs on torrent sites. It's not hard.
There is a libretro version of the DOSBox emulator. If that's what you want. It's not yet in the default installation but can be added using the core updater.
To be honest although I like the raspberry pi hardware (and would recommend it in comparison with some of the other boards) I'm not particularly a fan of the foundation also.
The reason being that they can't handle any form of constructive criticism very well. I dare you to make a comment about the USB design, open hardware vs blob thing, I will bring the popcorn. They have an extremely negative stance against competitors products which I don't understand. If it is real about the children and education I don't see how "competing" products that drives the prices down, are something bad in that regards. For me it is a healthy thing.
Personally since the beginning I've had a very negative vibe due to how to they communicate on their blogs, in comments, deal with people who have different opinions,... . I'm not one bit surprised that in the communications with the lakka dev(s) they made the impression of being unfriendly. You really don't have to be in direct communications with them to get that impression.
But they have the advantage of having a good product which in the end is maybe the most important thing. They make darn good inexpensive hardware.
The boards like Cubieboard are stuck with a 3.4 kernel (if you want to use GLES), because unlike other manufacturers, they don't pay people to ensure proper software support. Some manufacturers also claim software compatibility with the RPi images, which is impossible, but may trick some beginners in buying their hardware. Dishonest, right?
And yes, we sent a mail to the RPi foundation to ask for some free sample (we are not a commercial organisation) and they told us very politely to not expect anything from them. They ignored our request to include Lakka in NOOBS two times. Still, their hardware works and they pay enough people to work on software so if you want something that just works, go for it.
