"This archive contains recovered source code files related to the development of EarthBound on the SNES. Specifically, this is a snapshot of the localization scripting files as of, presumably, March 25th, 1995 (the file dates were destroyed when the files were originally deleted).
These files were recovered after deletion by performing a sector examination of the original floppy disk media. We have full confidence that the files are undamaged, as the recovered files were zip images that extracted without errors. We are not providing a disk image of the floppy itself, as it contains private data. All data related to the game that was present on the disk is preserved here."
