The hit rate for unlicensed games (and multicarts) seems Pretty Good, I've only had a couple of failures so far

Sometimes the carts even nicely match the system

More working games. The last one is GBA. Vast Fame's GBA games work but Sintax's don't. Honestly not surprising, they're picky enough about boot timing that they mostly don't even work on a DS, if anything was gonna fail I'd expect it to be those

more findings
- the Sintax GBA games with the "simpler" protection that work on DS work here too
- generally most unlicensed single game carts work
- multicarts are hit and miss but more work than don't work. sadly the VF 12 in 1 doesn't work
- strangely Li Cheng carts with their very simple protection don't seem to work, I wonder if the BIOS is rejecting the "Niutoude" logo (and does that mean this clone bios has a stricter logo check than the original....)

It has this library section which is supposed to log all the games you played but it only works on official carts so only one of the 30 I've tried is showing up lol

it wasn't sunny enough when i opened it to charge the glow in the dark i guess so i'll have to try and do that tomorrow and see how glowy it gets

Okay I got the 12 in 1 working we're good

so leaving aside its compatibility with weird carts.... my overall Gamer Opinion so far is that yes the screen is very very good and just about the best these games are ever gonna look
BUT i think it's less comfortable to actually play on than any official gameboy model i own? it's kind of a big heavy unergonomic brick of a thing

@lion didn't the GBA have a patched GBC bios that improved the logo check

@mavica_again Yeah it did but those Niutoude games worked on it anyway, I think even in the patched version it only ever checked the top half of the logo. I guess Analogue's reimplementation must be checking the whole logo.
