Oh wow. I actually owned one of those things back in 2011.
Don't believe it was ever updated past Android 2.3. You can use custom firmware / ROMs to get it up to Android 4.x, but at the end of the day it's a 12 year old smartphone with a single-core processor. You may be able to stick some old APKs on their and emulate NES/SNES/GBA, but any even remotely modern Android game would absolutely melt that thing, if it ran at all.
I think with the zergrush method, it can be rooted.
Then, you can install Android 4.0.4 on it, or maybe 4.1 as well. I had a Xperia Pro, same 2011 series and I ran Android 5 on it.
Those versions may have some apps that are still compatible.
