EDIT: I've figured out what ndspatch.dat does (Contains save sizes and ROM names) but I don't know if ndsinfo.dat replaces it in EOS? It's been awhile since I've used my SuperCard DS ONE V2 so I recently loaded EOS SP5 onto it and I'm wondering about some .dat files. First, I've had userpatch.dat in my EOS from prior versions but I can't find an updated one lately. What does userpatch.dat do? Secondly I've noticed in EOS there's also a "ds1patch.dat" file. Is this for AP patching? As a side note I found that the readme for EOS SP5 has a note at the bottom that says: "Note: Old version patch database can not be use in new OS. " Which patch database is the old one? My question to the community is which one is which and what do they do? Some clarification would be greatly appreciated.
