The reason Thermal Layers are used in conjuction with SH3Cmdr is because it's the only program available for SH3 that can randomise them.
Now, you could introduce the same settings into a JSGME ready package BUT the layers will not be random. Meaning that, you will always have a thermal layer @ 180m (for example).
Now the due to the way SH3 sensors work, this means, hit that depth and you're nearly 100% safe. It's a bit of an immersion killer.
