I'm attempting to install CWCheat on my psp, and I'm at the stop where I have to boot in Recovery mode. I know I have to press the R trigger while restarting the PSP, but I've tried COUNTLESS times and only get the normal startup screen. Is there any alternate why to boot in recovery mode, or is there a specific time to press the R trigger during bootup? How long should I hold it? Or should i just tap it?
