I do a bit of voluntary work in a place that has the full size version of these. My main gripe is the joystick. The ball bit is screwed on, not joined to the stick, so the ball keeps needing to be screwed back tight. Also I'm not sure if I'm just remembering things differently, but I'm sure the original sticks were longer. These feel too short for me.
Pretty sure the ball bits are always screwed on (Archer: Phrasing!). If it's coming loose some locktite or nylon plumber's tape should hold it in place.
Made one for my brother! Super fun, albeit a bit buggy. Nowadays Roms can be a bit tough to come by, and I've been meaning to upgrade him to a pi 4 but they are super expensive due to shortages.
pi4's are coming down at least here in the UK it might be worth reaching out to the community see if someone is near the store and if that wors out a bit cheaper. I would reccomend everyone keep a dedicated backup of their roms it's becoming a bit of a faff to replace corrupted copies 🥧 🐷
I love it because it's an arts and crafts project and a computer project all packed into one. I definitely want to try this. I think instead of buying something with RetroPie already installed I'd just get a cheapy mini computer and install it myself. You could totally get away with using old hardware from a pawn shop or yard sale, even.
