They really need to remaster the early game and just put it in XL version. I never play the XL version from DW3-DW5 because I didn't even know it was a thing, and combining them is so annoying for PCSX2 emulator
You may or may not be pleased to know that, at least with DWXL5, all of vanilla DW5's content is actually already on the disc, and the newest versions of that PS2 emulator has a patch you can enable to activate the content without the need for disc-switching. I hope this helps! (I don't know if the same applies for DW3 & 4 XL, but I know for a fact it does for DW5XL)
@Xaldin007 After watching this battle I bought a copy of DW4 Hyper!!! I cant seem to get it working on Windows 10, even after trying a couple of fixes. How did you get it working?
