I was trying it on my mac. I tried it on my pc and when I run jemplode.jar I get a BSOD.

Here's what I did.

Download and install the latest jemplode installer for windows.

Download the jemplode.jar and rmml.jar linked.

Added rmml.jar to jemplode/lib and replaced the jemplode.jar in jemplode/lib with the downloaded one.

Edited jemplode.lax.

Did I miss anything ?
