• We've got a Korean Lumines UMD now, and are actively working on creating a Korean downgrader. We can't give a release date, but it will be soon.
• We won't be creating a v3.51 downgrader, not for a long time. If you upgraded to v3.51 you're either stupid or unlucky. Sorry for that.
• You can't run the downgrader from a downloaded copy of Lumines.  If you read the documentation, you'd know that.  If you didn't read the documentation, just how did you think that would work?
• We won't be creating a downgrader for another game, not for a long time.  It's just not that easy.  If getting hold of Lumines in your country is expensive, blame the profiteering pricks that are hoarding their copies and selling them at inflated prices. When the exploit was first released, you could get Lumines for less than $20 in most places.
• It looks like Sony are introducing patched copies of Lumines into the market.  We advise you to buy either an old version (i.e. not Greatest Hits, Platinum or The Best), or check very carefully before buying a new copy. If you buy via Amazon, it may be better to buy from the 3rd party sellers, even though they are more expensive.
• We are working on the solution to enable you to go back to official firmwares if you need to - this includes helping people stuck on v3.30 or v3.40 v3.10 or v3.11 firmware.  It will take some time though, and we're all very busy right now.
• We're also still working on eLoader for HEN, and a flash management solution for people with semi-bricked v1.50 PSPs.  Those will also still take some time.
• The downgrader only works on Lumines, also known as Lumines Puzzle Fusion.  It doesn't work for Lumines Plus, or Lumines 2.  We've said that before, but for some reason people didn't read it.
