The rules are the same as any IENE, evolve the number by 1, and increase the effort of the project! Making mistakes will decrease the effort though, so try not to make one! You have to make the NE look and feel like Sviger 1.0, an NROS released in 1981 and minor versions continuing to 1983 with 1.5 Release 2.
