System RPL Files: Difference between revisions

Revision as of 00:02, 19 July 2023

Description

RPL files are utility libraries and drivers that can be used by Wii U applications. They are similar to .dll files on Windows.

Dumping

The correct path to system RPLs inside Wii U is:

storage_slc/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 everywhere to dump the files you want from your Wii U. The alternative, and more complicated, method is to use nanddumper to dump SLC and then decrypt and extract the files from it via wfs-extract.

Loading

Cemu normally emulates the system RPLs in high level. To force Cemu to load a system rpl file instead of emulating it, place the file directly in a folder named cafeLibs inside your Cemu folder. Do not copy all the .rpl files because many of them will cause Cemu to crash.

Make sure "Load Shared Libraries" is set in the game profile. Some older profiles erroneously disabled these, and the disabled state carries over to the custom profile file.

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	cemu version
`snd_user.rpl`	Extended sound effects for Sound driver 1	84,032	1.11.5+
`snduser2.rpl`	Extended sound effects for Sound driver 2	111,360	1.11.5+
`nn_sl.rpl`	Title management for Home Menu, doesn't really do anything	403,904	?
`swkbd.rpl`	Software keyboard (Title data required)	1,116,288	?
`nsyskbd.rpl`	Keyboard driver for software keyboard	20,416	?
`erreula.rpl`	Error System Applet (Title data required)	790,080	?

The keyboard files make name entry work in Pokkén Tournament.
All files except for erreula are required to boot Monster Hunter 3 Tri G(JP)
The swkbd.rpl being present will crash Cemu if the corresponding Title files for the Software Keyboard are not present in mlc01\sys\title\0005001b\1004F000
The erreula.rpl being present will crash Cemu if the corresponding Title files for the ErrEula are not present in mlc01\sys\title\0005001b\10051000
