Okay So the 4 values on the leftmost side of the screen are the frame rules, but if you set it to sock there will be more values there for you subpixels. The value underneath the FRAME thing is the frame that you jumped (it revolves around 255), the X thing is the frame you entered a room, and the R is the remainder of frames left because of frame rules. I might have missed something tho, I haven't used sock folder in a while

ive never used a pracite rom how good are they

They are very good, and super useful for learning the game
