All unpatched versions of Lumines are now supported when it comes to downgrading a PSP running firmware 3.50. The N00bz have provided an update to their 3.50 Homebrew-enabler (HEN) / Downgrader which adds final support for the Korean version of Lumines, ULKS46005. At last wee can all enjoy homebrew. Except those who have updated to 3.51.

Running a lower firmware version (< 3.50)? Update to 3.50, then downgrade!

Running a later version (> 3.50)? You’re out of luck, sorry. :(
