For RVZ what settings and Dolphin version is being used to build them. Alternatively is there any possibility to switch to using Nkit2 instead so that the RVZ result is consistently reproducable? The filesize and hash can change from version to version on Dolphin meaning the same file compressed to RVZ may not match if built with a different version.
The RVZ dat that official games are listed with used Nkit2 to compress.
