You need to enable luma game pathing to use this!, unless you prefer to apply the patch in any another way.
Just a little mod I made, I like SMG4 videos so I changed Mario's colors to blue and white; and also (and this has nothing to do with SMG4) I though that Luigi would look funny in red colors, (because is Mario's color scheme) so I changed it too (sorry if I say "I" too much). Sorry if Luigi colors look too dark, I tried to make them SM3DL styled, but as you can see, I didn't totally get it. (Also Mario was my favourite character, but I changed my mind years ago, so... That's also why I changed Luigi's textures to Mario's colors.
To install it you just only need to extract the files in the SD Card if you are using the EUR version, if you are using another version, change the name of the folder inside (the extracted luma folder\titles\0004000000053F00 (change this text to your title id for your region)
Ok, this is getting time-consuming, and sadly, I don't have too much time for personal things. So, I will still try to continue this, but if anyone of you wants to continue and make his own version of the next Ghost Marios, you have my permission (anyways you didn't need it, you could still do whatever you want). Anyway I am making now the SMB3 Ghost Mario, if everything goes as expected, you should have it for download later.
Edit- My computer doesn't want to work correctly and doesnt open the image editor, sorry i'll try to fix it.
This small mod changes SMB1 Mario to a ghost version of himself:
Here are the screenshots:
My version of the game is EUR, the mod works for other regions but you have to change the title id in the luma/titles/[yourregion] to your region.
Also, you just need to extract the luma folder to the SD Root, it contains the file in the correct folders.
I'll leave all the versions of the mod here in case you don't like the newer versions.
