Hex edit type effectiveness?

[Mega Swadloon]

Is there a tutorial somewhere to hex edit the type effectiveness?

I changed all the types on Firered, but t can't seem to get the Type Effectiveness Editor tool to work for fire red. I tried the newest one, and an older one and it won't work. I tried a clean Rom, still won't work. It works for Ruby, but not Fire red. So I figure I could just hex it but I can't find a tutorial or anything.

I already changed the graphics and the names in game.

The type effectiveness chart is located at 0x24F050 in a basic Fire Red ROM. Each entry is 3 bytes long, with the following structure:

byte 0x0: attacking type
byte 0x1: defending type
byte 0x2: damage multiplier (0x0 immune, 0x5 resistant, 0x14 super effective)

Thanks! I may end up using this info because I may want to add a new type.

Good news though is I found an alternative tool that appears to be working. So Incase anyone reading is afraid of Hex, I'll share this:

There are 2 tools for editing types that i know of. Type effectiveness editor, and Type Resistance Editor. If one doesn't work, try the other. The latter is a lot messier to work with, but it gets the job done.
