Newer versions of WinRAR should work too. You might need to download 7-zip to unpack them. Both packs are packed in the 7-zip format. Both packs are optimized through optiPNG. Porting is done for now with 1.825 textures ported The aim is to make the texture pack look as vanilla-like as possible. Just about everything should be covered for the international version, including some mods here and there. So what is SM64 Reloaded? It is an unified ultra high definition texture pack designed for Dolphin (through the Virtual Console), GlideN64 (for use on Nintendo 64 emulators such as Project64) and the unofficial PC Port. Thanks to the efforts of GhostlyDark (who primarily maintains the texture pack) SM64 Reloaded is available for the Dolphin emulator.
