NTSC overscan offset tried 0,0 and 0,8
That can't make any difference - if you're moving the screen by 8 pixels in Y-direction, there is no change in the bit order. What you need to change is the X-postion in single-pixel steps.

Oops! Silly me! Typo X, Y yes 0.0 and 8,0
Also the OS3.9 Overscan tool only allows steps of 2. I used keyboard control of the pointer to be more accurate...

That may actually be the root cause why nobody reported any problems until now. Can you try with a plain 3.1 install?
I just booted up a plain 3.1. No difference. The Overscan x offset only steps up in 2, i.e. 0, 2, 4, 6, 8... Keyboard control does move the mouse pointer by 1 but the screen rectangle does not shift, only every 2nd pixel move.
That's something we tried to debug, but couldn't, as a Mac emulator install is really hard to do without the ROMs. They used to be free on the Apple page, but that's gone now, and my last install has long gone the way of an old harddrive...
If you want to help in this case, please make an image of your installation and make it available to us, so we can find out of it's really an issue with Indivision, or with the WB settings that are required for Graffiti emulation to work. So far, not a single customer has sent us an image (or a copy on CF card), and the request came up a few times in this forum. To me, this feels like all customers have found a solution - for example set the overscan settings to an X-position that is divisable by 8.
I know this is an annoying setting, but that's what it was back in 1996 when the Graffiti came out. Indivision is implementing the original functionality - nothing more, nothing less.

Ok, this can be arranged, I'll send you some information later by e-mail or priv message

I have the overscan settings as recommended at the start of this thread. Games in PAL display correctly, with NTSC I have the same problems as the previous speaker.
The last reply was more than 365 days ago, this thread is most likely obsolete. It is recommended to create a new thread instead.
