No PI no. I got me an ODROID XU4Q - this should be the fastest thing in that ecosystem that exists atm.

I ran some preliminary tests - at first speed was disappointing. Lowering the resolution to 800*600 made a difference though. I also got errors initializing the video system.
This system does not support OpenGl - Gles errors... it is correct that it does't support OpenGl fully - only a subset. The weird thing is I don't have the errors anymore atm.
I will investigate further. I really only build the binaries and got my distro more or less on an acceptable level - graphics have been the least of my worries
'till now that is.

upon starting I get a black screen and I need to reboot - this is the log content upon starting wboy

is this the kind of log you need?
the fact that I got a significant speed boost lowering res and given the fact that the games are normally much lower res perhaps means some decent speed on arm with gm and 15khz could be obtainable.
Edit: I've had a look at the graphics - as I understand it now I need to build a loadable kernel module for the mali t628-mp6 and I'll need a user space binary blob. I'll try to find some time.
