As I said, it's more built to add compatibility with JPAN's Overworld Hack, as that still uses exactly the same table, but doesn't take into account that it's an entirely different Overworld table. The table is, with this hack, made entirely unrequired, giving us free space to use. However, arguably, the table would be easier to edit from a hex editing point of view.
Thanks for the opinion. I always appreciate comments and such, it's how I improve as a hacker. :D
