error reading psx game for psp

everytime i try to load the game after these words come out everything starts loading then it takes me bac to the main menu and tells me that the was an err i think the code they give me is 18ooo1 or something like that someone tell me what im doing wrong

Tell me:
Is your Firmware 3.02 OE-B?
Is your folder named SCUSXXXXX (X replaced by any numbers)
Is your folder inside the GAME folder?
Do you have KEYS.BIN and your EBOOT.PBP files inside your SCUSXXXXX folder? (EBOOT.PBP must be converted from a PSX .ISO or a PSX .BIN)

yes i have all that and i want to know if it matters what game folder u put it in cuz i have three one for 271 one for 1.5 and one that just says game

Put it in the GAME folder (nothing else)

my keys bin file just says Keys as the name should i put KEYS.bin as the name or it doesent matter

Try KEYS but I dont think it matters.
You sure you're at 3.02 OE-B? If you think you have done the process wrong try looking here at my tutorial:

Where did you get the game from cause I had same problem. I got mine from torrentspain.com, and they didn't work. Just goto torrentspy.com and enter in psp in the search.
