I have an announcement for anyone interested.
LibreElec focus is not on emulation nor games, they focus on getting Kodi working as best as possible, which they made an excellent job at!
Some changes from 1.6.5 to 1.8.3 seem to have broken a lot of stuff, and its very time consuming for someone like me to test each and every commit to LE to see if I need to change stuff around or fix other stuff. in This case advmame will be removed since there are a LOT of commits from one version to the other that broke it. I love advmame and I would love to keep it but its just not possible for me right now.
The same goes for BT, unless I can find an easy way to fix it. which is a shame as I know a lot of people rather use BT for the game pad.
But guys remember my focus was getting Emulationstation working along with other emulators and Lakka on the S905, I don't take credit for a lot of what made Sx05RE work, I don't even ask for donations or recognition since I know the real hard work was made by other guys, but I think I made a good job at getting everything working (sort of) together.
The Lakka team have focused themselves on getting emulation working on these devices, and everything there works perfectly (BT, advmame, ES, PPSSPP, etc) and since I don't use Kodi at all, I am thinking of just moving everything to Lakka even if that means loosing Kodi, I know most of the people that use Sx05RE use if for Kodi first and games second, but its just getting to hard to maintain for a guy that knows very little about how linux/LE works and mostly works by trial and error, pair that with a crappy laptop that takes about 8 hours to compile one version from scratch and you get a lot of wasted time trying to get one thing fixed.
If you focus is sing Kodi first you can always "installtointernal", and use a SD card to boot to Sx05RE when you feel like you want to play some games, or there are now other options like the IARL that work on the S905.
That said, I will still try to fix the remaining bugs on 1.8.3 but my focus will now be moved to Lakka.
