You need the latest NIGHTLY of Luma3DS. This is why you don't see the Enable Game Patches option.Well, I'm trying this and it loads with lines
I have an Old eur 3ds with arm9. I have enabled "Autoboot SysNAND" and "Enable region/language mu. and ext. code" and
I put the file in: F:\luma\titles\0004000000164800 (code.ips)
Am I doing something wrong?
