i would love to see an zinc-like arcade core for psx based arcade games [like Sony ZN,Namco System 11, Taito FX1 and so on]
i know mame has support but i tried Tekken 3 on Current MAME with an i7 7700 which has somewhat good single core performance. the game still has some smaller graphical glitches and some minor slowdown with shitty latency settings (thr. Video on, swapchain 3, No framedelay, GPU hard sync off) . Overall not that great i guess. The Same i7 with Swanstation and beetle psx can run the Game (as PS1 Port) without noticeable glitches with several hundreds fps and no Slowdown even at lowest latency settings. Even when i enable software renderer in both PS1 cores, they are MUCH faster than MAME and are more accurate.
