Hi everyone, I am very new in this field, so please bear with me :)
I have my problem in my UMD because it suddenly hidden after I used the ISO Tool and tried using Promotheus v4 in Metal Slug XX. ( I did that because I tried in FF IV Complete Collection and it worked). After I clicked that patch sddenly my UMD is empty but in the properties there are the files and I cannot see it.
Any one know how to fix this ??
