#### Help with the self-hacking Pokemon Blue Version (-kinda)

Anyone know what kind of program I need for editing the data to allow the self-hacking to happen? I found a hex editor and tried to use that, but it did nothing for me.

What do you mean by "self-hacking"? If you're looking for ways to use Arbitrary Code Execution, you might want to check out the 8F thread.

Both TheZZAZZGlitch's and my self-hacking Pokemon Red/Blue videos have information about the bytes you need to change to implement it in the description (including info about how to make it a faster/slower corruption):

> Every 17 ms, there's aproximately a 1 in 4 chance that a random byte in memory (WRAM area in the range C000 - DEFF) gets corrupted, that is, overwritten with a random value.
> Implementing this hack (in hex):
> Starting at address 0040, write: C3 A6 3F C3 24 20
> Starting at address 3FA6, write: F5 C5 D5 E5 CD 5C 3E E6 03* A7 20 14 CD 5C 3E E6 1F C6 C0 67 FE DF 28 F4 CD 5C 3E 6F CD 5C 3E 77** E1 D1 C1 F1 C3 43 00
> *Try 07 for slower glitching (1 in 8 chance) and 01 for even faster glitching (1 in 2 chance).
> **Alternatively, try 34, 35, 70, 71, 72, or 73.

They aren't exactly the same, but both versions (TheZZAZZGlitch's and mine) will work.

I was asking for a program. I've already read through the instructions numerous times

I'm sorry you couldn't get the changes you wanted. Are you using Windows? For other platforms, these may be some open source hex editors.
The hex editor I personally use is a freeware program known as HxD, for Windows. It can be found here (fifth row).
You will need to open the ROM (make sure it isn't marked read only on Properties), then type in the changes. It may be quicker to get to 3FA6 with Search>Goto… 3FA6 (on hex).
If done correctly, the changes should look like this.

Afterwards, you can save your ROM as another .GB file.
It could be that you entered the wrong values by mistake, as it's easy to do that or forgot to save the changes, or maybe your hex editor just didn't work.
Make sure that you overwrite the offsets without inserting bytes (if you inserted bytes the last offset is no longer FFFFF; avoid that) or the hack may not work.
I hope this helps.

Spoink also has a Pokémon Red/Blue ROM hack with a self-hacking script already enabled.

I already had it on my computer. I just did not know how to do the hack.
