## nes20db.txt
This file stores NES 2.0 data about NES ROMs, generated from [NewRisingSun's nes20db XML file on NesDev](https://forums.nesdev.org/viewtopic.php?t=19940). Converting updated versions of the XML file to this format requires compiling and running [NES20Tool](https://github.com/Kreeblah/NES20Tool) with the following options at runtime:
NES20Tool -operation transform -xml-file nes20db.xml -xml-format nes20db -format-transform-type sanni -format-transform-destination nes20db.txt
## snes.txt
This file is needed for odd sized SNES games like Final Fantasy (JAP), Super Metroid(US/JAP) or Tales of Symphonia. Without this file you will get overdumps and the checksum calculation will fail.
