I want to go back and play my favorite GameBoy games, and want to find the best way to do this on a handheld device. I have lots of cartridges, but ROM support would be nice! I've looked at Steamdeck but I'm not sold on it yet... the Analogue Pocket looks lush but expensive. The Miyoo Mini Plus looks promising, and the RG353V almost looks too good to be true. I specifically want to play GameBoy and GameBoy Color games, bonus points if it can do GameBoy Advance.
I'm surprised no one mentioned the Analogue Pocket, especially if you had cartridges. It does have support for ROMs as well. One of the best features is that you can sleep your device on even original cartridges
After a long time of going to the Analogue website and looking at the Pocket, I ended up ordering one. I usually play on my GBA, but the Analogue Pocket is really promising as the best device to play the original GB/GBC/GBA cartridges!
