I recently failed trying to install the newest version devhook (not enough space) and now when I try to re-install 0.46 the ISO devhook which lets me hook up the the pc is missing. I realized that the first time I got rid of Devhook the GAME folder had 5 sub folders (All Devhook) and I was also checking for space and saw that the missing file was 48KB but I see a file with the same amount named EBOOT.PBP which is in a folder named __SCE__DH_ENG.

Some other information

1. The firmware is on the PSP is 1.50 from a previous downgrade.
2. I'm using the Devhook 0.46 install program, I think its buy Chaos Zero (UI_v1.1.1.exe)
and when the installation is finished there is 817kb left when it was previously 500kb exactly (total MS size 32MB)
