This is a jlp kangaroo, with precalculated tame kangaroos.
You can make them yourself. By running a kangaroo in the required range with the -m 3 parameter in a loop with a false public key. In this way you will accumulate a lot of DPs.
After that, you will only need wild kangaroos.
This requires modification(s) to JLPs script.
Hi, this sounds interesting to me. Are You able to provide link where that modifications are explained? Or is there maybe a repo with modified software? Thanks for help.
