A bit of background - my computer died on me. Luckily, I was kinda expecting it, and had thus saved my Touhou stuff to flash drives. I plug it into the new (lesser ;~;) computer, and all is well for a while, save for me actually having to live with slowdown.
Until I transferred it all to a bigger flash drive, that could hold all of it. Now, as noted above, TH06, TH07, and TH08 don't work; also, my vsync patch .rar managed to have every .dll vanish from within it. When I try to start any translated game, it just... doesn't do anything. When I start untranslated EoSD, the screen goes black for a few seconds, then I get the error in the first picture below. When I start untranslated PCB, the screen goes black for a few seconds, then it doesn't start or give me an error message or anything. When I start IN through the vsync patch (the only one I had actually applied the vsync patch to, more because it would let me play at a decent resolution without screen stretching than because I had screen-tearing issues), I get the error in the second picture below.
Any suggestions?
