For some reason, this bootleg has never been dumped as far as I can see.
It's mostly a text edit, but with pokemon locations edited, as well as some barriers removed, I assume in order to let you see the whole thing as fast as possible. You can buy master balls for 0 pokebucks.
There are a lot of slurs, but it's not as offensive as most of these kinds of hacks.
I have no clue where this thing actually originated, just that it's being sold as a cart on ebay and the like.
