USBUTIL replacement for formatting PS2 ISOs for OPL. Extract this to C:WindowsSystem32 and run this from the command line. Works with all PS2 ISOs, even ones larger than 4 GBs.
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
