A Quick Diversion:  

The Actual News:

Oh man oh man oh man…. long story short, apparently the guys behind the Space World Demo Leak (of which I’m still in the process of making a fake card set for) and the “Capsule Monsters” Gen 1—or rather, “Gen 0”—leak which only revealed their backs is at it again with nearly ONE GIGABYTE worth of dumped stuff covering Gens 1 through 6, though the real big stuff is from Gen 1-2.

A quick view of what’s in the MEGA Download

The most basic outline of the real hot stuff is summed up in this post from 4chan/vp/:

>What got released?
Debug Builds of Blue and Yellow
Source code for Blue and Yellow
Japanese Debug Builds of G/S
Symbol Map for Crystal.

>Where can I download all this

Oh, yeah, that’s the link with everything in it, all 900+ MB worth. Download it while you can!

But in case you don’t want to compile beta versions of Game Boy games, I do have a few bits and pieces I swiped from /vp/. Take a look!

So this is just a small taste of what the folks over at /vp/ worked out and discovered… there’s plenty more where this came from, and I’ll probably end up trying to find some other stuff on my own as well! Either way, I’ll also most likely end up making a video about all this as well, at least once more info is out and there’s more to talk about.

But without further ado…

First off, I have a bunch of screenshots showing off some of the various text which was changed from the initial English translations in the final English releases. There’s some interesting tidbits!

Apparently they were going to have limits on how many items you can buy at PokeShops?

And then wait… you can just tell the PokeShop owner that you’re “just looking”?

Meanwhile, you can see some of the names for various items or even Pokémon which were quite different back when the game was still in development.

Gallop and Ninetails? Korattavar? Did that come before or after “Ratattack”? And can you imagine singing your praises to Lord Snail?! PRAISE SNAIL!!

Meanwhile, it’s interesting that they were going to call it “Report” before ultimately choosing “Save”, seeing as that’s the word that is STILL used to this day in Japan and Korea for game saving.

Finally, here’s a couple examples of dialogue changes to make the game more appropriate for it’s intended audience. So no straight-up killing Pokemon (even if Pokemon are still able to die), and definitely no dialogue that might conjure up a Chris Hansen asking any NPC to take a seat over there…

Here is a sprite sheet showing some characters which don’t exist in any final Pokémon game, including an actual cat? Maybe I’ll animate this sheet in a bit…

Included in the files is a map editor, as well as some old maps which don’t exist anywhere in game. In particular, the top map depicts a very early version of Pallet Town! Now apparently some of this is actually known, but what’s new is the ability to see the maps in their rawest form.

Finally there are some vector graphic artwork… the first is a mock-up of what Pokémon Yellow would look like when released in English, while the last picture is… well, see for yourself!

WHAT WAIT?! “Catch ’em if you can!”?! I mean, can you imagine the Pokémon theme song, or even the PokeRap, using “Catch ’em if you can!”? I dread to think about it to be honest. I’m just glad they used “Gotta Catch ’em All!” instead!

This is just a small taste of what has been discovered! If you’re interested, I’ll keep sharing whatever I find and give a bit more solid analysis of what’s going on. For today however I just wanted to share that this even exists to begin with. But now that the cat-genie out of the bag-bottle, there’s no going back… so, more to come!
