Is it possible to get android 8 on this device? I am very Happy with LegacyRom, but i cannot use yaba sanshiro anymore. I know skelton is not on development anymore. But i don't know where to get source code to try porting something higher. Thanks anyway.
Skelton always shares the source code:

At this point is extremely unlikely that someone will develop a new rom for the original xd, so if you don't want to be stuck with kitkat your best option would be buying a xd+.
The problem is that Saturn emulation is pretty broken on the XD Plus, so he'd get a worse experience than just sticking to the XD and an older version of Yaba Sanshiro.
