I can make a 704 x 280 PAL overscan screen, but in AMOS the NTSC overscanned screen seems to max at 704 x 248 - 240 is standard NTSC so I'm a bit confused and probably missing something regarding NTSC - also I would like to get it to 724 but it cuts the display.
in fs-use NTSC @ 60hz is graphically smoother so I've started to use it, but found the smaller vertical a problem and don't want to change the display until I work out if something is wrong - any ideas?
Thanks

Is your machine NTSC? If so, using a PAL booter may help it to recognize the screenmode.

When working the width X dimension of your screen you can only multiply it by units of 16 the height Y dimension however can be any number of pixels you like
16 does not go into 724

240 is standard NTSC
thanks for the replies, but um, ooops, no it's not, apparently it's 200 horizontal for ntsc, so overscan is working at about 241. http://amiga.lychesis.net/knowledge/ScreenModes.html
actually, this just tells me I need a real amiga if I want smooth graphics again...

200 vertical, you mean?

lol yeh, maybe I do a popup screen for it :-)

The new oscilloscope is much smoother in ntsc as the fps matches the graphics card:
I'm open to suggestions of what to do - there are missing buttons at the bottom...
-
reduce the button border and the slider height if NTSC is detected?

hadn't thought of that, thanks, I changed the buttons to be 11px and it all fits.

Guess thats me done then.

maybe not ;-) - do you know how to get larger than 704 out of AMOS?

Resolution or Screen Size?

Resolution or Screen Size?
Looking at the Resolution - I've set the default screen and editor screen to be 704 by 280 so it is in "overscan" - fs-uae will auto zoom so it looks fine but there are extra pixels available up to 752 by 286 shown for the screen mode...
UPDATE:
in Editor_Config.AMOS I tweaked the XDI variable, the Limit Mouse settings, and Screen Display and MAXX variables - I got it up to 736, but there was a little chopped off on the right. I could send the screen position much further to the left but then the mouse would disappear - I think it's a hard coded limitation - somewhere in the amos.library source?

Out of curiosity I tried the link, but couldn't get it to work. Firefox 3 displays an error and claims it can't find the server. I also tried pinging the site, but still couldn't find it. Are you sure the domain name is correct??
-
yeh the link is dead?
and I've got a new issue - I've been given a windows machine so trying winuae and the overscan is totally different :( but I haven't played with the settings yet.

looks like i'm stuck with 640 as the amos screen won't shift left, fs-uae has an auto-zoom effect which is doing the nice overscan!
but I've found out that WinUAE and FS-UAE are actually quite different in other ways, and something wonderful has happened to the "memory" bugs I was getting in fxbox - it doesn't guru in winuae :D :D :D when the memory gets fragged you just can't allocate it, which is fine. but in fs-uae it will guru the amiga - interesting.
next chance I get (don't get much time on this any more...) I'm going to delve into the amos.library to see where the screen data is set and hack a way to move the display offset...
