I had installed a custom theme on my PSP slim a month ago. It included a custom video and sound when a game was started. I then learned that I could no longer play PSX games if game_plugin.rco was modified. Luckily, I had backed up my flash0 before I modified it. I replaced the file, and the PSX games run again.
However, I think I may have accidentally changed something else at the same time. Now my PSP displays the custom gameboot video, and the official one, at the same time, one over the other. It's very strange looking.
Is there a way I can correct this?
I did a quick search both on these forums and on Google, but I couldn't find anything particularly helpful.
