lucienEn Posted January 4 Share Posted January 4 Hi, I started creating a screen editor that can generate assembler code based on screen contents (and validate in case not enough cycles to do that). I wonder does this already exists before I spent more time on this? This is work in progress and code generation hasn't been added, (NTSC) color selection, background and playfield editing plus load/save work. Question: I noticed the coordinates shown in Stella differ from grabbing a snapshot: for example left corner of Pitfall is shown as: x=8, y=40. But taking a screenshot it shows as x=16, y = 17. The x difference makes sense since it's 2:1 ratio, but not sure why it takes 23 scanlines (instead of the full overscan area)? 1 Quote Link to comment Share on other sites More sharing options...
