At 8:33, notice how it named my OPL partition as "+OPL1", saving OPL options will only save to a partition that is named "+OPL" So if this has also happened to you, delete the +OPL1 partition and create a +OPL partition again. It should work the 2nd time. If not, let me know. At 17:13, Make sure to select "Save CNF to MC0" as well as MC1 and Mass. I apologize for my failure to mention this. As far as I know, no one has created a video showing how to do this. I looked all over the internet until I found every step to complete this 2TB PS2. I am making this video tutorial for myself, my friends, and the people of Reddit. This works with Hard Drives and Solid State Drives of all sizes. (I have not tested HDDs larger than 2TB, supposedly you can still use hard drives with more space but it will only allocate 2TB) Original Text Tutorial: https://gbatemp.net/threads/ps2-using...
