Cemu now supports WUA files which are better compressed than WUX and lossless.

If you use zlib instead it works OK… Example command line below.

chdman createdvd -c zlib -i game.iso -o game.chd

The output CHD’s are slightly bigger than the ones created with zstd but it’s still a big size drop from the iso.

I guess it’s https://www.gamebrew.org/wiki/NDSTokyoTrim…

It’s supposed to work for GBA too, I wonder if it’s lossless / if we can convert the trimmed file to its original format.

I was able to reduce storage by 4GB. Please update your video with this info.
