Hi, is there a way or maybe a dll to read pixels directly from the screen like in memory bank? Thanks.

Use DOS and Mode 13H. -cb

yes cb, Dos is a good idea ;) using readpixelfast & writepixelfast is slower than peeking or poking directly into a buffer. I know there are functions to do this in blitz + buy why not in Blitz 3D ? thanks!

I may be mistaken, but isn't Blitz+ an entirely different code-base for the compiler (closer to BlitzMax under the hood than Blitz3D). If that's the case, improvements behind the scenes might have made it possible in Blitz+ where as the code base behind Blitz3D doesn't lend itself very well to the methods required to do it. Like comparing Apples to Oranges. Speculation, of course.
