The parts fit perfectly into an og gba shell, and look great, but as the title mentions, there's just slightly too much flash (excess material from injection molding) left on the shoulder buttons.
It'd be worth if retro gaming parts can speak with the factory to see if anything can be done about it.
As it is I'll be filing the parts by hand to remove it, and while it doesn't affect functionality, it does make the buttons less nice to use
