Good evening. Today I'd like to show you how to play The Binding of Isaac Afterbirth on Wii U. This requires you have hacked your Wii U, obviously. If you haven't done that, I recommend visiting http://wiiu.hacks.guide/. Because using custom DLC like this requires CFW/Sigpatches, Haxchi or Coldboot Haxchi is highly recommended. The Binding of Isaac Rebirth got DLC in 2015 on PC called "Afterbirth" that was a large expansion to the base game, including many new items, synergies, new alt stages, and new music in some cases. This DLC later came to the PS4 and Xbox One in May of the following year, prior to this point Tyrone Rodriguez, the CEO of Nicalis, Inc had made several statements on Twitter stating "Stop lying to yourself, the Wii U is not much more powerful than a PS Vita." which made some news headlines at the time, and a lot of angry Nintendo fans as well. Months later, Tyrone posted this tweet, showing him at the top of a Daily Run (which was a new afterbirth feature) on the Wii U, and then, in March it was confirmed for release sometime "in the coming months." I have news for you, Tyrone. It's been a lot longer than a few months and it's still never released. It was later on confirmed that Afterbirth+, the next expansion, wasn't coming to Wii U but was instead confirmed to be coming to Switch. So here we are then, Afterbirth was apparently up and running on Wii U and was planned to release, but it just never came to be. Or did it? Well, sort of. The final update, 1.06 of Rebirth on Wii U, in the USA version only is a file named "isaac-ngWiiUAB.rpl". Based on the name, you can see this is an RPL (Wii U Executable) for "AB" or Afterbirth. While the game executable is here, the contents, of course, are not. But are we really missing them? Isaac uses pretty standard open formats for it's game data, even on consoles. And we have the afterbirth content for the PC version of the game... Someone, specifically @Dr.Aardvark, decided to go ahead and try and recreate the data it wants using the PC version files as a base, and apparently, he achieved success. He even posted about it late last year, but the thread didn't get much traction, and honestly, as a guide, it's a bit lacking. I actually followed it nearly exactly but still had a bit of trouble getting it to work myself, but eventually I sorted it out. As he mentioned in his thread, the only caveat is that the Daily Runs do not function, as- of course, this platform does not have the required servers to support them, instead, returning an error when you make an attempt to connect. It is still unknown if there are any major issues with playing Afterbirth this way, but as far as I can tell, everything that should work does work. And now, I'm here to sort it out for you too. May I present to you: Afterbirth Wii U Builder This is a simple windows based batch script that uses various open source tools to build a working DLC installable WUP package that enables Afterbirth out of the PC version's afterbirth.a file. In order to use this script, you will need: The Binding of Isaac Rebirth on PC/Steam The Binding of Isaac Afterbirth DLC on PC/Steam The Wii U Common Key (Google It!) A working Java runtime installed The short instruction manual is: - Copy afterbirth.a from the PC version of Isaac Afterbirth into the same folder as the script. - Make a text file with the exact name "encryptKeyWith" containing the Wii U Common Key. - Run Build.bat and wait a while. If you get an error you probably did something wrong. A more detailed set of instructions for the less technically inclined are included in the zip file's readme document, so feel free to check on that too if you want. If all goes well, it will output a folder named "The Binding of Isaac Afterbirth [0005000C101A3C00]" which you can copy to your Wii U's SD card in the install folder, and install it under CFW/Sigpatches with WUP Installer GX2. You will also need The Binding of Isaac Rebirth (USA) installed on your Wii U to make use of this DLC. Please let me know here if you encounter any issues with the script or if you are unable to get the DLC to work in some way. Enjoy, everyone. F.A.Q. Q: Afterbirth+ or Antibirth? A: No. The only reason Afterbirth is possible is that Nicalis spent the time, money, and effort porting Afterbirth to Wii U themselves, as evidenced in above paragraphs. To make Afterbirth+ or Antibirth work on Wii U would require far more work and effort. Q: Can you upload to <insert warez site here>? A: No, but I'm sure someone else has or will. Q: Can this same tactic be used to enable Afterbirth on n3DS or Vita? A: No. Those only contain executables for Rebirth, not Afterbirth. This only works because Nicalis ported Afterbirth to Wii U themselves already- they just never released it for some reason. Q: Why not the EUR version? A: Majorly, the EUR version doesn't contain the "isaac-ngWiiUAB.rpl" file which is the whole reason this process is possible for the USA version, but it's worth noting that you don't want to be running the EUR version at all, as it is actually out of date by a whole update, compared to the USA release. It seems that while porting Afterbirth to Wii U they made a ton of performance optimizations that are not present in the last EUR release, that make both Rebirth and Afterbirth performance much more reasonably on the console.
