Doh, I forgot I meant to ask you if you had a chance to reply, but did anything change in how things are rendered to the screen at all between the 10/2 build and the 10/15 build? Sorry I don't have a smaller window there, but those are the two builds I am comparing between. Some of us are seeing a vertical tearing effect on the left side of the screen in various emulators (for me in CatSFC, haven't tested others). Its noticeable big time in the Metroid video I posted earlier. The thing is, its not present in the 10/2 build, and not everyone is seeing it apparently in newer ones. Figured best to get some insight from the man himself!
