I think just turning all the graphic options on gives the best pic. Same thing on different era games. For instance, Vector Games are displayed at a higher resolution then the older raster games. I know Mame kicks the resolution around depending what game is loaded.
I hope that eventually the MAME devs will have a set of presets already bundled with MAME for the HLSL settings base on the different makes of monitors that where actually in the arcade cab for the rom that you load through mame.From Game List - If you set up a game list. So i thought id start a thread on possible preset or even suggestions on the settings i have to make a more authentic CRT arcade monitor look on an LCD Display. There are loads of different settings to tweat and to be fair theres alot i dont know what it actually alters.
There is a good post.fx hack you can do in the mame folder for vertical games where it changes the view point of the screen so it looks like your looking down on a old vertical cab style view point. Do they work for vertical and horizontal games just the same? If I want to change the brightness/darkness of the scanlines (as if adjusting the pot on a SLG3000 for instance) whats the best number to tweak in your opinion?The good thing about HLSL is you can alter it and save it for each game, as the odd game it looks odd so you can tweak it for that game, it will work for vertical and horizontal games but as said for vertical you might need to tweak it. Copy the extracted folder in /opt: sudo cp -a opendingux-toolchain /opt.Last edited by lettuce on Wed 7:59 pm, edited 7 times in total.Looking very nice on your screenshots, thanks for sharing, I'll give these a try tomorrow.
Usually best used at a multiple of your playing output resolution. Here you put 3 for a 3x pre-multiplication in vertical pixels)Hlsl_preset = (Currently an undocumented setting)Hlsl_snap_width = (This setting sets the width for huge resolution 'rendered snapshots' that can be created by default hotkey &. For example, if you are playing a 320x240 game at 960x720 then you are using a 3x magnification. Here you put 4 for a 4x pre-multiplication in horizontal pixels)Hlsl_prescale_y = (This setting can give you a 'sharper' image depending on what resolution you play games at.
Using the default 'aperture.png' you will notice moiré effects. If you use the default aperture.png you need to use an even smaller number here to remove the moiré effect)Shadow_mask_texture aperture.png = (Name of shadow_mask 'overlay' file)Shadow_mask_x_count = (Here is where we tell the HLSL file how many times to tile the 'aperture.png' to fill the resolution. For example 960 high x4 = 3840)Shadow_mask_alpha =(visibility of shadow mask, when using big game display output use small numbers here. Usually best used at a multiple of your playing output resolution.
Unrevised setting)Defocus = (I don't use defocus as is only used to add blurriness to your game image, yuck!)Converge_x = (I don't use, suppose to offset pixel position by colours)Converge_y = (I don't use, suppose to offset pixel position by colours)Radial_converge_x = (I don't use, suppose to offset pixel position by colours)Radial_converge_y = (I don't use, suppose to offset pixel position by colours)Red_ratio = (leave alone, red ratio 100%)Grn_ratio = (leave alone, green ratio 100%)Blu_ratio = (leave alone, blue ratio 100%)Saturation = (this is saturation, how strong colours look/bleed, don't set too high)Offset = (I don't use, suppose to offset strength of red,blue,green)Scale = (I think of this like brightness control, where 1.0 = 100%)Power = (I think of this like contrast control, where 1.
