Hi im new here! First sry, i have terrible english! Idownload from http://emu4ios.net/ a Retroarch emulator. My device iPad Air without Jb. So i Install a emulator and because i havent Jb i use Itunes copy a Psx rom (Final fantasy 7). So Ff7 work perfect, but i try inerase a game graphich, becuse i see few youtube video where a player use this emulator on Ipad with final fantasy 7, but have better graphic than me ATM. After i start run a ff7 i see a options “prev. shader” and “next shader” , i use this 2 options but nothing happend. So how this function work? Where cna i find good IOs iPad shader pack (if need this), or how i inerase a game graphic? If i havent Jb how can i use a shader pack, or how i inerase somehow a games graphich? Thx u answears!!!
In the in-game menu (called RGUI; the one with green text), you can go to settings > shader options and load shaders from there. The ‘load shader preset’ button will let you choose glslp files, which contain powerful multipass shaders, but they are likely going to run slowly on your device.
To load a single-pass shader, change the ‘shader passes’ to 1 instead of 0 and then, where it says ‘shader #0’ you can navigate to a new shader (it should come with a bunch of them, though many will be too slow on your device; start with easy ones like ‘scanlines.glsl’). Be sure to click on ‘apply shader changes’ to enable the shader.
