My SORX mod (stage 3 from BK2 beta) street level, I split it into 2 (the scroll scene and diagonal scene) to make them same gameplay as original.
Because I tested out for street stage of BK2 Beta, then roll down made Vertical scrolling begin too.
First scene is Scroll Left so that I can put 1up behind the front layer. The front layer speed is 1.6 (like Charco's placement). The next scene is Diagonal Left, front layer speed is "full" and if you walk forward (or on top.. ignore stage of above) until horizontal scroll begins to walk down.
The front layer in scene 2.. I chopped off from scene one gameplay where the test character standing at.
thanks to original screen with pixels.
