When I start my modded .iso in PCSX2, it just shows a black screen for a few seconds and then crashes. My unmodded .iso boots just fine. Here's some screenshots of my files/folders (if more are needed, let me know. Also, I followed the formatting, but you have to right-click each of these and select "open image in a new tab" or whatever equivalent option in your browser. Not sure if this is normal on here for Imgur links):
P.S.: When I hit the preview button after initially finishing off this post, I was brought to a login page, even though I was already logged in. When I got in again, it erased the entire thing and I had to start all over. Maybe because I put my PC into sleep mode in the middle of writing? Seems like a bug, though, and one worthy of investigation.
