I'm having a bit of a hunt around the house for stray micro SD cards. I got one of those Anbernic Gameboy SP style handhelds and I heard the SD cards they ship with aren't great.
No luck finding one so far, which is to be expected, but I've ordered one anyway. No analogue sticks on this thing so it will just be retro 2D games.
The ROMs it shipped with have been decent and in English. Only one hasn't worked but I'll swap it out anyway.
