we are working on many things in same times,
First, about the Experimental OpenGL plugin, we are implementing a new very important feature that will let you choose your Rendering Resolution... this make Emulation much faster especially on Device with High Reslution like the Galaxy S4, the HTC one or the Experia Z.
Firsts tests give excellent results and even more, like the tekken3 bug menu with no Characters Image is fixed.
Other advantage is that drawing PSX with res 1280x720 on FullHD res screen make image smoother... and still very detailed.
Another Enhancement has been done on GPU Soft plugin on which i fixed a Bug in Sprite routine which Fix many problem in many games, like the Background on Many Games ( in example the Sky in INtro of Ape Escape etc...)
I have detected a Big problem in .Bin and .Img handling support, for next version more ISOS will be recognized.
Other Problem seems to be fixed like Moga Pro controller (for this one i need beta tester )
Many other Fixes has already been done.
