For current Reshade version here: https://reshade.me/ D3D8to9 is required to work: https://github.com/crosire/d3d8to9/releases Although, for this game it's better to use "Better Rayman" as substitution of D3D8to9 (it has also numerous fixes and special, brand new configurator): https://raymanpc.com/forum/viewtopic.php?f=89&t=12854 Install it, and launch BR3_Config, and choose your resolution (supports widescreen) and check Hardware Vertex Processing. Press OK. It fixes graphical glitches in d3d8to9. Now edit d3d8.ini and in field d3d8to9 change 0 to 1 to turn it on. Since now, Reshade works. ___ For injecting Reshade in Dolphin: download Ishiruka Dolphin, and install Reshade as OpenGL while having default DX11 renderer set in Dolphin's settings.
