@folly Sounds like great progress! Ingenious work with the PSP battery.
I bet PS2 is decent for emulation, they are powerful enough in retro terms. PSP seems more fun - I like the handheld retro aspect.
I've got an XBox One and a decent laptop as well, I like modern and retro. There is some messing around to get games to work sometimes on Windows - I had trouble with Jurrasic World Evolution this week, took me a day to get it working (it didn't like booting up in anything other than 60hz 1080p). I'm playing Halo Infinite now as well - it is so good for a free game (only the multiplayer is free though).
