The coolboy carts have all the necessary resources but does not support Neil's unusual choice of mapper. He used this mapper to conveniently address a large amount of WRAM. You could go through his ROM and hook and change all the mapper writes but this would be time consuming! I've emailed him regarding a fork of his source but he is a very busy man and have not heard back from him.
You could build the mapper into a coolboy cart with a few logic IC's and some SRAM, then you could run Pulsar on it.
I could download his other various NES ROM's and test their compatibility...
