disabling filtering for 2d pixel games

[petran79]

I recall that when I connected the Dreamcast to a LCD TV via VGA cable, 2d pixel games like Gunbird 2 or Street Fighter Grand Master Challenge were very blocky and pixellated.

However when I choose vga output on Flycast, Gunbird 2 has automatic smooth filter, which is not how it looks on original Dreamcast at all via VGA.

Is there a way to disable filtering completely for similar games relying on pixels?

I'd like to experience with a vga monitor at 240p that has its own native scanlines.

The rendered image is displayed using linear filtering to the screen or window. You can force filtering to Nearest in Settings > Video > Texture Filtering > Force Nearest-Neighbor.
However this will also affect all textures in the game, which may have unexpected consequences.
Another way to avoid linear filtering is to have a window or screen with the same resolution as expected by the original Dreamcast.
