To view HI-RES stages is really simple and personally you should have had some idea of how to do it. also it's not a software; it's a method.
1st step: complete your stage
2nd step: order your stage elements from what supposed to be in the back to the ones in the front.
3rd step: download a character that can fly and use one that can fly at a decent speed. we don't want a fast view of the stage.
4th step: Add this code to the bottom of each element(sprite) coding. layerno = 1
5th step: enter your mugen then go to training and select your stage. you will notice you don't see anything but your stage anymore.
6th step: Press your pause button and change your range of your opponent character to CLOSE.
7th step: Now just fly with your character around the stage. please fly in a conventional way so people can view the stage properly.
