NHigh is an N 1.4 highscores statistics program written in Python and created by highscorer jg9000. NHigh is a useful and compact program that can download and analyse highscore charts before generating various lists. NHigh has since been developed to 2.0 by eru_bahagon; the current version is an upgraded version by EddyMataGallos, which can be found here.
N2High is the successor program to NHigh (created by EddyMataGallos), which downloads statistics regarding N 2.0. Production on the software began in May 2013, and the first version was released on 31 July 2013. In 2017, a version (also made by Eddy) was also made for N++. It can be downloaded here.
A master list of 6,897 N 1.4 highscores can be downloaded here, spanning 2006 to 2018. The list is not comprehensive, but it does cover a considerable amount of data points and gives a significant background to the history of N highscoring. Similarly, a database for N++ highscore history is also available here.
