This game is for DS right? Damn, I probably actually know how to make the cheatcode. Sorry but I don’t really feel like putting in the work to do it, though. I can give you a button-activated cheatcode I use for Advance Wars though which you could easily adapt to Fire Red if you found the RNG address and the value you need for crits/claw to activate.

The first line is the button activator. That’s B in the example. You can look up button activators here:

The second line is the actual code. First is the RAM address for RNG, then the hexadecimal value you want to cheat it to.
The last line I’m not even sure what it does, but it’s some sort of “closure” that’s usually put at the end of all Action Replay codes. Maybe. It doesn’t matter.
So just go find the Fire Red RNG RAM address (just look it up online I’m sure someone posted it already) figure out what hexadecimal value would activate what you want and put those values in the second line. Then you can activate the code by holding down B or you can look up in the page I pasted the other buttons’ values. Depending on how Fire Red’s RNG and stuff works it may not be as simple as doing this, though.
My god I spent too much time writing this I’m not even gonna check if I said something wrong or not. Anyway this should help you.
