Here are some screenshots from a couple of them:
Looks pretty cool but gets old quickly.
2. Blur 2
There are 4 different blur settings. The first one actually looks pretty decent, but the rest are too intense for me.
Hmmm. Can't really see shit... Kinda like if your favorite SNES game came out on Atari first.
This one actually looks really cool. It makes everything look like Yoshi's Island :D
There are a number of others in the pack, including all of the blurs, another take on bloom, a toon shader without the black outlines and a couple that cover everything with a wave mask.
This pack gives D3D users a bit more freedom beyond the lone Sepia filter that comes with bsnes, and I hope to add more of these in the future. I'll post them here if/when I come across them.
I fiddled around with some and came up with a couple more. They're essentially functioning just like mudlord's 'emboss' shader, but they maintain color:
1. color emboss bright
2. color emboss mild (this one requires that 'smooth video' be enabled to work properly; similar results to smooth video+mudlord's 'sharpen' shader)
