I use to play around with a little device called Open Pandora (from when System-On-A-Chip really became a thing; it looked like a bulky Nintendo DS and was mostly used to emulate old games (including Nintendo DS ones, interestingly).
I made an alternative desktop environment for it (so you switch from using XFCE to Openbox).
Anyway, this wallpaper reminds me of that time:
I can’t remember. It wouldn’t have been for emulation, because I’m never been that bothered about that. I remember it seemed terribly important that I get one, because I paid extra to skip the queue of pre-orders. I ported software directly on the device itself, but - yeah - I think it was mainly for audio/video stuff (using it like a fragile and cumbersome iPod touch)
