I tried to make a gameboot with the directions in the "create your own gameboot" (or whatever it's called) tutorial thread. I have my gameboot.pmf and I viewed it on my computer, it looked fine. I flashed it to my psp with the 3.02 OE customizer and everything went fine. It went back to the XMB and I decided to test it out with a homebrew app. The gameboot didn't show at all, just a blank white screen with the PSP logo. I've heard of gameboots not working in custom firmwares like in this incident, but what steps can I take while making my pmf to make the chance of it working higher?
