Mario Tennis - Unfiltered - left part of the screen is rendered on the right side

[Pixelnarium]

I am using m64p on ArchLinux here. This does not happen in filtered mode. I also tried some other games like Mario 64, Blast Corps, Turok and Mario Golf and it does not happen there.

This happens on angrylion when unfiltered too. @ledgendofdragoon had a work around for this in his tests.

Maybe it's an overscan thing? Meaning that it happens on real hardware but it's hidden?

[theboy181]

I think this happens on the real hardware if you disable the filters too. I would need to test again to be sure though.

How can I disable the filter on real hardware? Do I need an UltraHDMI for that? I "only" have an Everdrive but I can't find a "disable AA" cheat for Mario Tennis. But maybe this is a different thing.

There is a few lists with aa codes around. Usually they are applied via cheat codes.

Lack of VI filter isn't causing this issue. It's the fact that his code for non-Vi filter displays extra pixels. Angrylion did tests on real hardware and determined that a certain number of pixels in each row are never displayed (first few and last few pixels). It's easy to fix.

Thanks, I thought we had tested this. Why did t al fix this issue then?

[Pixelnarium]

I think this would explain some other observations I made. Ms. Pac-Man and Virtual Pool 64 have the same problem like Mario Tennis. Virtual Pool 64 just on the left side.

In some games it looks like this:

Hm... I could easily fix it, but the question is: how many pixels should be removed from the left and right? In filtered, it's 8. But in filtered, the width is always 640, unlike in unfiltered.

Why did t al fix this issue then?

He never implemented non-Filter.

But in filtered, the width is always 640, unlike in unfiltered.

I would just see where it would normally start after scaling width to 640.

Okay, I'm using the filtered mode for reference and just rescale the cropped area when in unfiltered mode. That appears to work just fine for most games, but it needs more testing.
