I have a .cia of Yume Nikki (found in a Youtube Video comment section, if I recall correctly) but two days ago it crashed while playing, so I tried to create a new .cia myself with up-to-date files.
I followed the istructions in the cia builder readme here and extracted the game files in /romfs, but when I launch the game on my console I receive the error “romfs: is not a valid path”. I also tried with a subfolder /romfs/yumenikki, and in this case the message becomes “sdmc:/3ds/easyrpg-player”, so EasyRPG is not able to locate the game in a subfolder and fallbacks to this path. If I place the game in this path on the SD it works, but also kind of defeat the purpose.
What am I doing wrong? Any input is appreciated.
