To conclude the problems with PS2 emulation, we come to hardware rendering. The PS2’s graphic pipeline acts very differently than modern GPU cards and emulating it in HW mode with a certain degree of accuracy it’s hard: due of the versatility of PS2, and the fact that it doesn’t use fixed shaders, games don’t follow a precise formula to how achieve different effects. Various type of enanchments like scaling leads to the typical “black lines glitch” because of using a non-integrer resolution. The OpenGL backend on PCSX2 greatly improved these issues, but most games still requires “software rendering” to fix most of the glitches. Games using mip-mapping (Ratchet & Clank, Ace Combat) and games running on the Snowblind Engine are playable in OGL HW mode with minimal problems.
