Getting BSNES filters to work with a Genesis emulator

RetroArch Additions Shaders
#1

Quick disclaimer: I know next to nothing about coding and all that! (But I’m definitely willing to learn what I need to do.)

RetroArch looked really cool, and I followed the guide here http://filthypants.blogspot.com/2011/11/advanced-ssnes-configuration-options.html, using the BSNES filters (64-bit) provided. It worked really well with Snes9x, but I couldn’t get it to work with Gens Plus GX—the screen would be weirdly smushed. I did come across this https://github.com/Themaister/RetroArch/issues/5 which describes my situation perfectly. However, I can’t find a “genplusgx-ntsc-git-x86.dll” anywhere, and I’m not sure how to compile/where to find the proper “Makefile.”

If there’s a really obvious solution or place to find all this information, I apologize in advance!

you can try these builds (win32 and win64 in the same archive). I haven’t tested them, but I passed them the ntsc=1 flag while building, so they should have NTSC filtering built-in.

Let me know if they do/don’t work for you.

Thanks! I tried both (the win32 with the 32-bit version of RetroArch and the win64 with the 64-bit version of RetroArch), but unfortunately when applying the BSNES NTSC filters, both still had the same problem. I tried out the Composite and RF filters I had, as well as trying out the filters from the BSNES 0.81 release. Changing things under Video didn’t do anything to fix the problem, either.

Ah, my bad, it was case-sensitive and didn’t pick up ntsc=1. It needed NTSC=1 -.-

Here are working builds (I tested the 32-bit build in WINE, so I assume the 64-bit version works, as well).

To be clear, these builds don’t fix it to work with the separate NTSC filter(s), but rather roll the filter in so it’s already applied automatically. Just guessing, it looks like NTSC-RGB (i.e., rather subtle)… You’ll have to lock aspect ratio and force 4:3 or else it’s stretched out really far (I’m guessing to the 512 that the filter expects).

If you really want the NTSC artifacts and stuff, which are subtle in that version, you can try applying this NTSC shader from cgwg and Themaister to the normal, non-NTSC genesis core.

Cool, thanks! Yeah, both of those cores work just fine. I did try out the shader, too, but it makes everything black and white. Looking at that blog I linked to earlier, I guess it requires shader spec 1.1 emulators to run properly. Still, pretty interesting.

Thanks again!
