I feel very happy, this old computer has managed to do something I've been struggling for months.
The only issue I have found so far is been I can't hardware emulate the graphic card cause it just crashes the entire computer.
Within the fact the software emulated graphic card is a bit slow(even the shaftswift looks ugly), it kindly works, even the audio.
Initially to solve the crashes I added a 12 gb of swap file(to see if the 8 GB of ram was the problem) and it flawlessy started, then, I tried with hardware emulation and kept crashing, so I will buy a new video card when I have the money :)
Should I post a short tutorial on how install a "natural" side emulation of android for linux/windows?
Also, I found an app for android phones where you can have multiple accounts for the same games without logging out from your main account.
On my phone I installed Parallel Space.
On the android emulated one I installed GoMultiple or something similar. Any interested?
