Firstly, I couldn't settle with 1.43 because it has that mouse issue where if you play something like the fly swatter game in Mario Paint (fast erratic movement), the cursor stops mid screen, believing it has hit the far edge when it hasn't. Moving the mouse to the other side and then back temporarily fixes it until it happens again.
I'd love to try 1.53 to see if this issue was fixed (as I have experienced, the latest 1.6 versions have indeed fixed this, so hoping it goes as far back as 1.53). It's supposed to be a universal binary that runs on both PPC and Intel versions of OS X 10.4, but so far, I can't get it to work.
Tried it on my G3s and G4 MDD, all running 10.4.11 PPC of course, the snes9x icon just appears in the dock and then disappears and doesn't launch. The Terminal states "incompatible CPU-subtype". I've tried all downloads of this, even 1.52 for the heck of it, they all do the same thing. What can I do to get things working?
