I’ve this Blueretro adapter for my PS2 fat, looks like it need to be additional powered by the USB port thru cable, I’ve read some models may need this so I suppose it is a common issue? Also, do you know if ulaunchelf need a wired controller? Because isn’t working with this adapter.
(Edit) Hmm…I’m starting to think that my ps2 has problems in working


There are versions of uLaunchElf (maybe the fork wLaunchElf) that have drivers for more controllers like DualShock 3. The drivers are optional because space is tight on a “Memory Card™ (8MB) for PlayStation® 2”.
This one? Thank you btw
