Need Help with CwCheat>3.40 OE-A

[Vijore]

Hello, I am TOTAL noob with PSP information or hacking etc..
My Psp System Software is 3.40OE-A

Ive tried many different cwCheat.. and had many different results..
Some of them worked perfectly in plug-in but when I enter the game and hold 'select' button to show menu.. it doesnt show.. (The person said to go into specific game selection part and hold select button once I am there.)
and the others.. plug-in wont even show..

The game I'm trying to hack is DjMax Portable 2.
I want to play the Link Disc.
Its like.. switching UMD.. You have Portable 2, and you want your psp to think that your changing your UMD to DjMax Portable 1..
I do have both portable 1 and 2 files, and I do have 2 different duo sticks..

Help me wit this.... The closest I got was up to in enabling the cwCheat.. but menu not showing up..
Thank you..

the problem lies in your memory stick+firmware bad iteration... in 3.40 the only viable way was getting a good memory stick or flashing the prx. another solution is updating to an m33 firmware and using m33 no umd modes (umd and other iso modes won't work) or going up to 3.90m33-2 which is the first firmware which waits for slow memory sticks to be mounted before skipping plugins
