I'm not totally sure, but I think you got about 30px on vertical, maybe extra 50 or so left and right ? I have not seen this done in any other res, not sure if it can be done, maybe someone else here can help you better.

Though its not a simple removal of borders, it switched between 50hz and 60hz constantly to get the bottom border removed, but this takes up a lot of CPU time. I assume it has not been done in med res as there are more pixels at work so its possible the CPU just isn't fast enough. I think removing all the borders will take up most of the CPU time anyway.

In anycase, the more borders you "remove" the more cpu time it will take, You end up with very little CPU time after a full removal. HTH.

Thanks guys.

i think that i have found another way to skin the cat.

The thing is that i am thinking of making a drawing program for the Atari, but on the PC.
so insted of a fixed resolution for the no border mode, i think i will make it, so you can chose a custom screen size.

but thanks again.
Best Regards
Peter
