Hi Guys, new at this, so please bear with me, I'm making a new emu box that I can have by my tv. but I'm struggling with running most Opengl games, ps1 (beetle psx hw), dreamcast (any) and I know I'm going to have problems with others. retroarch is my main issue as none of these will work at all, but stand alone emulator (for psx) will work great. I'm now pulling my hair out as I don't know what to do. my system is i5, 2500k with 8gb ram and GeForce 1050gtx graphics please help me
