It's been a long time since I stopped using homebrew on my PSP, but today I decided to downgrade again using Lumines and installed 3.40 OE-A.
The first thing I tried was the RemoteJoy application, which after a couple of hours I got working with Ys. Now I tried PSP Comic and got an error, "The Game could not be started. (8002014C)". This looks very familiar from my early days of homebrew. Am I missing something? I got the same error with some of my old emulators and figured it just had to be a different format or something because they were old.
