Ok so my basic goal is to use some replacement images I found online and using them for some of the character sprites/textures. My main problem rn is that I can’t find a way to recompress the two folders form the arc.cmp file back into an arc.cmp. I’ve seen other people online have the same problem but no real solution and every guide I follow is for a different game and the software they use doesn’t work with arc.cmp. I’ve been looking for any solutions and I can’t find to seem any. If anyone could point me in a direction that can help or if anyone would be willing to help it would be greatly appreciated. I have a few other smaller issues with what I’m trying to do like some of the sprites from the games files look chopped up and rearranged when I view them on Ohana3ds rebirth. Also after I extract the edit the image from the game and export it as a . bfilm I can no longer view it in Ohana3ds rebirth it only lets me export it as a .png but I can view the original unedited .bfilm from the game. Any and all help would be greatly appreciated.
Below are the steps I took to arrive at the problems I am at now. Just incase there’s something I’m doing wrong or an easier way to do what I’m doing.
So what I’ve done to get to where I am now is dump the game using godmode9 and then decompressed it with PackEnglishV12. With that I go through /romfs until I find the arc.cmp file I want to edit. I use ohana3ds rebirth to extract two folder inside /blyt and /timg. In /timg is a .bfilm with the texture I want to replace. (The full length version of the character sprites look like they have been rearranged and idk what or why it is. Some explanation will be nice
I'll attach a picture to make it more clear) I take it to switch toolbox to export it as a .png. That .png is taken to gimp. Now in gimp, first layer original .png. I drag and drop replacement .png into gimp making second layer. I make original layer invisible merge then export .png with original file name. The .png looks good I go back to switch toolbox to export the .png back to a .bfilm looks good but now when new .bfilm is brought into ohana3ds rebirth it no longer views it the only option is to export as .png idk if that means i did it wrong or if it doesn’t mean anything but it doesn’t mater because after use the new .bfilm to replace the old one I couldn’t figure out how to take the two folders /blyt and /timg and recompress them into a arc.cmp file. This is my first rom hack but I’m not new to modding games or editing file so I usually can find some sort of workaround online for my problem but for whatever reason I cannot find any solution online anywhere I am out of options I need some help with this one.
TLDR- how do I recompress two folders into an arc.cmp file
