@JastersAccount I think CVagts and Seya isn't actively using this site anymore. Best way of seeking changes is to contact Tetsuya directly, although I guess he doesn't have forum notification for the Suikoden games.

Also note that there are already existing non-NG+ runs done for Suiko4, although I guess the runners didn't bother to submit it here yet.
