These shaders are from the DeSmuME team. I did not write them. I made some small changes so the shaders can work in MAME or HBMAME. Place the shader directory from the attachment next to your MAME or HBMAME executable. Update your mame.ini or hbmame.ini with settings from the attached mame.ini. The shaders run slower than Zenju's C++ code, but work well.

MAME actually has had a proper data-driven shader system for the past couple of months now, using the BGFX rendering backend. Had you gone that route, you could have submitted the shaders directly to the MAME team for inclusion in mainline MAME. As it is now, though, it's a hack and can't be included. crazy46guy MAME Fan Reged: 06/28/13 Posts: 15 Send PM Re: xBRZ Shaders for MAME and HBMAME [Re: MooglyGuy] #355170 - 06/02/16 02:09 AM Reply How do write BGFX shaders?

As example you can take a look at the already implemented HQx pixel filter. e.g. /mame/src/osd/modules/render/bgfx/shaders/chains/hqx You compile the shaders with the regular MAME build tools and the command line 'make shaders'. The shader binaries are built into /mame/bgfx/shaders/[backend]/[shader]. In addition you need to define some meta information like uniforms, sliders, targets and passes. e.g. /mame/bgfx/effects/hqx The format of the effects/*.json files is documented in /mame/bgfx/effects/default/blit.json. e.g. /mame/bgfx/chains/hqx The format of the chains/*.json files is documented in /mame/bgfx/chains/hlsl.json.
