I was looking around in the flash0\vsh\resource directory of my slim because I wanted to see if a custom wave would work, so I deleted a file that I thought was the 'system_plugin_bg' accidentally (I was on the phone helping a friend out, my fault still) and replaced it with a custom wave which originally worked on my Fat PSP. I assumed that the wave would work, but now I am left with a semi brick, and stupid me forgot to even dump my own flash0.
So to anyone who reads this, I am asking, could you please send me those 2 files(default system_plugin_bg.rco and the file I deleted) from your slim's flash0? Both are in the flash0\vsh\resource directory, and I remember that the file I deleted had a size of 85 KB. Any information or suggestions on what I can do to replace these files is greatly appreciated! Thank you.
