This is a a new test version of the Sx05RE Kodi Addon for S905 and S912.
I removed the Libretro database file as it was the cause of the long installation time, if you need it you can reinstall it from within Retroarch.
I included PPSSPP, Reicast and Advancemame to this version, but please note that they work on the S905 but they might not work on S912, please let me know of any problems.
There is a setting in the Addon to start Emulationstation (default) or Retroarch.
You will need at least 650MB of space in /storage to be able to install this add-on, and that does not include ROMS but If you want to use an external HDD or a USB for your ROMS, make a directory called "ROMS" in the root of the USB device, then inside create an empty file called sx05reroms, place your ROMS inside the corresponding folder (nes, snes, etc, etc.) then with the device plugged start the add-on.
You also need to put all of your BIOS files inside /storage/roms/bios/ (or if using the USB/HDD inside /roms/bios/) dreamcast bios goes into /storage/roms/bios/dc
Note: You need to enable external sources to be able to install this from zip, it takes about 4 minutes to install (lots of files), while its installing there will be no status update (not sure why) and it will look like Kodi is not doing anything but it is installing, be patient!
also, not all the options in the Emulationstation menu are working, they will be removed/fixed later.
Please let me know of any problems you find.
