It's seem came after i full charge the battery and/or the charge still connect to N3DS and electric outlet.
But it's goes off after a while and goes off quickly if i remove...
I swear like 99% of arcade games wouldn't even exist these days outside of MAME the arcade machines are old and busted very few ever saw any sort of home conversion
I mean if a company could use AI to do the work of a home conversion for essentially free why not? The rights for some games are completely lost though
