I actually end up using my FPGBC more than my backlight-modded GBC these days, it’s just nice to not have to worry about maintaining ~30yr old circuit components lol

Definitely check out makho’s firmware repo https://github.com/makhowastaken/GWGBC_FW and docs if you go this route, using these I get perfect compatibility with all authentic game cartridges (flash carts can be a little iffy, but the point of this device is to play original carts, so imo not a big deal, but worth stating).

+1 for FP - fantastic hardware and if you order direct from them it meets the requirement of ordering & shipping from China.
