MAMEWorld Forums - EmuChat - Re: HLSL pixelperfect pure Scanlines

Personally, I like the crisp scanlines option myself. But using the scanlines function didn't get me there. You can get it looking close with that, but it never looked quite right and I had to tweak it for each individual game (some games need wider lines, etc.). I found that I got what I wanted using only the shadow mask function (with the attached 2-pixel mask) and disabling scanlines. This also addressed the problem of having to change it when going between fullscreen and windowed modes. This gives you a baseline of 1-pixel lines (the minimum) which you can easily increase. Thus:

shadow_mask_tile_mode 0
shadow_mask_alpha 0.25 (increase if you want darker lines)
shadow_mask_texture scanlines1_2.png (rotate this file if you want to use it for a horizontal monitor)
shadow_mask_x_count 2 (increase for wider lines if you're using a vertical monitor)
shadow_mask_y_count 2 (increase for taller lines if you're using a horizontal monitor)
shadow_mask_usize 1.0
shadow_mask_vsize 1.0
shadow_mask_uoffset 0.0
shadow_mask_voffset 0.0

scanline_alpha 0.0

There are still a handful of games I had to increase the x/y counts to 3 on, but this generally worked and I didn't have to spend all day fucking around with scanline settings.
