Well, as long as the game becomes playable I don't really care how it happens. I had trouble getting the auto torpedo solutions to hit anything with TWoS installed previously, but I've since brushed dust off my manual skills so I guess that's taken care of now. After I removed the patch and tried vanilla, I realized it was an unplayable mess.
At the moment I'm enjoying the crap out of SH3 with WAC though. It would be nice to have SH5 in working order to spice things up too
