0okm is reporting on a rumor that suggests the Japanese "Greatest Hits" versions of Lumines have been patched to require Firmware 3.51.
It's unknown if the actual exploit has been patched, or if Firmware 3.51 was just slapped on the disc. If the latter, it may still be possible to downgrade using this disc.
Until more is known, you might want to stick to the used game bins for Lumines now.
