The test makes a character and a picture (that looks like a character) walk at the same time, you can choose one of the six speeds. However the animation is not perfect. And I don’t have a better PC to capture the screen to replicate the movement. But the movement is totally accurate.
When I test it using EasyRPG only one parallel process works at a time. So only the picture moves and not the character, also it goes too fast, compared to RPG Maker 2003. I think the speed of RPG Maker 2000/2003 is 50fps.
You can use it to benchmark some things, like accurate character movement.
