Right of the bat, on
OpenGX build..........
Castlevania Symphony of the Night / Akumajo Dracura Gekka No Yassoku: BLACK SCREEN AFTER KONAMI'S FMV, game technically still runs and plays, but graphics dont display at all!
Dead or Alive: Broken Graphics on top and bottom. (see below Point 1)
Tekken 3: Broken tilemappin seemingly fixed with almost to no jitter or frame stutter!,

however Menu Graphic Overlay and Select Screen still dont display!
Mortal Kombat II: Runs fine, full speed, graphics arent overly blurry at 480i or having tilemap errors, but background color layer does not display correct colors in certain stages. (see below Point 1)
Mortal Kombat 3: Same as MK2
Mortal Kombat 4: No issues here, perfect!
Rockman X4: No issues here, perfect (aside from upscaled openGX graphics)
Kyutenkai Pinball: Still slows down during menus and transition screens, main gameplay is at full speed (odd)
Note: FPS Counter does not display
As for Old GFXs and New GFXs, things seems the same as always at first glance, with games running more jittery and stuttery on New GFX, specially Interleaced titles, SOTN and 2D titles just dont seem to like this one for some reasons, and yes i read that the bugfixes for some titles aint incorporated on this new OpenGX build.
Also still a bit weird to have PS1 3D games rendered at higher resolution via OpenGX, the increase in speed is awesome, but i see its still need work to be done, would it be able to render at normal 1x PS1 sizes and 2D graphics with no errors and at 240p?
Point 1: You guys are familiar with Background Color layer right? that does not display right in many games like it should, MK2 for example.
