I'm only posting one game I need help with for now, but I think this might be useful for a general thread of patching problems.
This morning, I downloaded the rom for SaGa 2 for the NDS from *romsite removed*. A while ago, I had downloaded a translation patch for it, but have been waiting for a chance to download the rom.
...But I've tried many things to get the translation patch to patch on, but nothing works. I keep getting "Xdelta3/too many file names" errors. What am I doing wrong?
