8bitdo Ultimate 2.4 Ghz, it connects with a dongle, but if you update the firmware you can use Bluetooth as well, even though they don’t advertise it. You can also go with the Ultimate C 2.4 Ghz which doesn’t have the back buttons or mappable buttons (I don’t even know if 8bitdo’s Ultimate software works on Linux) to save some money.
Great soundtrack, picking up the missile powerup in the first level, exiting the level to sell it, repeating until you could afford the twin blue lasers.
