Mame games are primarily arcade games, right? Did you see any presets with the word Arcade in the filename? I don’t make presets specific to cores or emulators, I make them specific to systems. If you read some more of the thread you might better understand why.
There are various reasons for this. The main one being I don’t generally delete a preset once I like it. I just iterate, revisit or re-imagine. In addition to that, most of the presets are interlinked, thus building on the work that was done before.
One nice thing is that when you try to load preset in RetroArch, they’re all grouped alphabetically so you can use these groupings to help sort things out.
You’re new to this niche or scene. Take your time. Eventually things might start to make more sense to you.
Slot Mask, Aperture Grille/CyberTron, Shadow (Dot) Mask - these are different types of CRT screens, so games would look differently on each type once the user is discerning enough.
Smooth means there is smoothing or some sort upscaling.
Composite is a type of TV signal which has its own unique characteristics.
Raw means no smoothing. I haven’t used Raw in a while.
Sharp - You can’t figure out or guess what “Sharp” means?
Maybe you need to read some more. You can try this approach. In the 4K_Optimized Folder, there’s a folder called CyberLab Neo-GX. You can start with those if you’re on a 4K screen.
Other than that, you can try the Soqueroeu-TV Special Edition Folder or CyberLab Special Edition folder.
What you can do is read this thread, especially the entire first post and the Please Show Off What CRT Shaders Can Do thread and if you see any images or screenshots that you like you can take note of the presets used, then just load them up.
If you don’t need the Mega Bezel, you can try some of my other, newer preset packs.
If it’s still frustrating or confusing then maybe this preset pack is probably not for you at least not at this time. There are several others, some which also employ the Mega Bezel Reflection Shader.
