System RPL Files
Description
RPL files are code, that can be used by games or Wii U applications.
Dumping
The correct path to system RPLs inside Wii U is:
storage_mlc/sys/title/00050010/1000400a/code
You can find other copies of those files in the Wii U but they are just backups or old versions of the system.
You can use ftpiiu_anywhere to dump the files you want from your Wii U. You can follow the online guide but in the end copy the files from the folder above.
Loading
Cemu normally emulates the system RPLs in high level. To force cemu to load a system rpl file instead of emulating it, just put it in a folder named cafeLibs inside your cemu folder.
Tested files
These below are the files tested and known to work. Other files probably will just lead to games crashing on boot.
| filename | usage | size in bytes |
|---|---|---|
| snd_user.rpl | Extended sound effects for Sound driver 1 | 84,032 |
| snduser2.rpl | Extended sound effects for Sound driver 2 | 111,360 |
| nn_sl.rpl | Title management for Home Menu, doesn't really do anything | 403,904 |
| swkbd.rpl | Software keyboard | 1,116,288 |
| nsyskbd.rpl | Keyboard driver for software keyboard | 20,416 |
