hey wait. hold on awhile. my lum,ines isnt uljs19005 i just found out. its uljs00005 and theres some guy on playstation forums who has this:
Yes, I was complaining about this, but I solved it before Noobz. I will come out with the downgrader for Japan Lumines as well. And this works, I tryed it on my friends copy, now excited about downgrading for my 67th time
1. Download
this2. Extract the contents of the 'ULJS00005' folder from the ZIP file into the 'SAVEDATA' folder in your memory stick. (HINT: MS_ROOT>PSP>SAVEDATA)
3.Start the game, and as soon as it gets to the 'Press START' screen, or whatever it is in Japanese. If you wait until the demo has started, the exploit may not work.
4.The screen should go blank, and the exploit will start after a few moments. It doesn't do anything except look pretty at this stage - but feel free to enjoy the first homebrew on your v3.10 - v3.50 PSP
Here's a picture of the exploit in action:

yes all that. but some how i downloaded it but doesnt work. and maybe you could explain the difference between uljs00005 and uljs19005
