Most mods have individual release threads here on the forum where you can download the respective .iro files. If you do follow this route, be advised that many mods have seen numerous updates since what was put into the current catalog, while others weren't even around yet, so their names often won't match what's in the FAQ/Getting Started guide. Just slot them using their equivalent is (e.g. Satsuki's FMV upscale pack is equivalent to "Media - Movies") and you should be fine.
