Hello, my name is Atlas. I'm mostly known for my videos in my YouTube channel.

I am an experienced and experimental Mario Kart Wii/Mario Kart 8/Mario Kart 8 Deluxe modder, programmer and administrator from this wiki. I like documenting and testing new stuff, specially file formats, as well as creating my own tools for them. Recently, I got certain interest in coding for Mario Kart Wii as well, and thus I'm learning much more about how the game works internally. However, I'm investing most of my time into working in projects, such as the Translation Project, as well as datamining, creating tools, learning languages, designing in 3D, and much, much learning.


WHackR is a Wiimmfi region specially made for hackers, where they are free to use cheats without the risk of getting banned.

I'm probably one of the few players still alive who enjoy using cheats and hacks online for fun. I've had my good times hacking online in 2013, and I always like to get those memories back. Since it's not allowed to use cheats in the new server, Wiimmfi, I made a modification of a file from the game that allows you to connect to a special region where you can only meet hackers, and cheat safely without ruining legit players. At first, I decided to call this region "47145" (note that this number reads as "ATLAS"), and it would have used the region number 47145. But since this region wasn't allowed, I decided to change the name to WHackR (Wiimmfi Hacker Region), and it currently uses the region number 191. This region is also accessible via code, which you can find in the following video's description.

Official announcement and release

Atlas's Custom MKWii Packs

Shortened Atlas's Packs, they were the first mod packs I started to make, back in 2014. The original packs were never released, but the content inside of them is still available in some of my AKW packs. The development stopped in December 2014 at version 5.4, and was followed by the start of the development of the AKW series. Then, it was merged with the release of AKW v6.


AKW (also known as AVD Kart Wii and Atlas Kart Wii) is the name of my first public set of packs of custom Mario Kart Wii files. The development of these packs was restricted and it was stopped the 7th of March of 2016 with the release of the latest pack, AKW v7. The latest packs were popular because they were a completely mess of random files, which were organised as a maze where you needed keys and passwords to get the mods. I didn't decide to do this only for fun, but also because I wanted the files to stay as rare as possible.


This is the first texture pack I made, developed in 2013. It only contained some basic textures.

AKW v1

The first released version came along with the second version, released in May 2015.

AKW v2

The second version of the pack started being developed at the end of 2014 and was finally released the same day as the first version. Despite it being incomplete, shortly after, the third version was also released.

AKW v3

The start of the development of this pack was very recent relative to the release date, although it contained updated stuff that was planned for v2, mostly.

AKW v4

Developed at the same time as v3 and released in June 2015, this huge pack contains a pretty big maze of files. Good luck getting them all!

AKW v5

At the same week after the release of the first two AKW packs and the end of the AKW v4 development, a fifth version was planned, and released the 18th of June of 2015. This pack contains a whole new Common.szs with 8-bit style items.

AKW v6

After a long time without any releases, in November 2015 I announced the arrival of AKW v6, a huge pack with lots of new mods I've worked on since the release of AKW v5. This pack didn't contain any maze at all.

AKW v6.alt

Within the development of v6, I received many requests of custom file commissions. This led me to make a paid pack, called AKW v6.alt, which contained exclusive content, and also it brang the arrival of the "Private" folder. The v6.alt folder is not paid anymore, because of the Private folder leak issue.

AKW v7

This is the final version of AKW, released in March 2016, twenty days before the big leak. It has by far the hardest maze of all the AKW franchise. The development started in January of the same year. The password to extract the pack was My name.

AKW v8

There was an AKW v8 plan in hold after the seventh version release, and it was supposed to contain many new things that are nowadays released, although not into a maze this time. The big leak caused me to stop the development of this pack and I released the supposed content into the "After-leak" folder.

Private folder

The now obsoleted Private folder is a MediaFire folder where I released exclusive content I shared with people who wanted to purchase my mods. The folder consisted of a set of files and sub-folders organised by date, since there was a new folder weekly. The members who paid €10 had a full month access, the ones who paid €20 had 3 months and the ones who paid €50 had permanent access to the folder. The reviews from the users who paid for the folder were positive, since it was very active and there were a lot of new stuff every week. Also, the ones who paid for the access of this folder had permanent access to the v6.alt folder, which access was separately sold as well for €4.99.

The creation of the folder was processed the same day as the start of the development of AKW v6.alt. The users who donated me also appeared on my recommended subscriptions list from my YouTube channel.

Private folder leak

The day 26th of March of 2016 a user purchased a €10 one month access to the Private folder. The following day, I discovered via Skype that they were sharing the stuff from the folder with more users, even after he promised not to share it with anyone else. This led me to immediately stop the file sharing with them, but it was too late: they got all the files and he leaked them. The main consequence of this was that I couldn't sell access to the folder anymore, since it would have been unfair for those who paid for the files that now anyone had access to. The complaints also led me to refund the money to the users who had an active access plan, which made me lose more than 60 euros.

Next to this issue, I decided to stop the development of AKW and I kept uploading the content that was planned for AKW v8 into the After-leak folder.

After-leak folder

This folder, made the same day of the big leak drama, contained the stuff I was developing by then, planned for the cancelled AKW v8. The folder was completed the 5th of September of 2016.


AKP, also known as Atlas Kart Pack, is the follow-up of the AKW franchise. The difference between AKP and AKW is that AKP was a set of MKW modding projects of both finished and unfinished stuff. The development of the pack has been discontinued, since I now work on more stuff other than MKW, and now I also store my public stuff into my AVSYS server.


AVSYS or Atlas Vryzas System is a development environment which contains tools I use to mod games, documentation, templates and other utilities. It contains my own toolsets as well as other common public tools, plus tools and source code from Wexos, who has helped me a lot in programming. The environment has its own Wiki that you can visit here.


This is the signature given for my software. It stands for Atlas Vryzas Software, and you may see it on my tools.


VRZ_SDK is a software package developed from 2016 to 2020. It contained all of the code and formats I made in that time range. Its filetypes (such as VBDP or VBFGA) started with V as the codename I used for them (V stands for Vryzas, my first surname). In January 2020, VRZ_SDK came to an end and I started a better and more organised toolset.

In 2016 I started organising my private work into project packs. These packs contain everything modding-related except the SDK tools, including mods for Mario Kart Wii, Mario Kart 8/Deluxe, Super Mario Odyssey; as well as source information for my own research and modding requests. The list of projects can be found here.


Codenamed Project_2017, the first project's development started in May 2016 and finished the 31st of December 2017. The pack contains the latest stuff I made until 2018. I first had plans to release part of it, but later decided that it would stay private.


The second project, codenamed Project_2018, started right away at the start of the year 2018 and finished in January 2019. The pack's structure is pretty similar to the previous one, although it contains more stuff from Mario Kart 8/Mario Kart 8 Deluxe and from other non-Mario Kart games, such as Super Mario Odyssey.


The first compiled project with the new tools was Project_2019, which again, began at the start of the year 2019 and finished in January 2020. Its structure is even better than the previous one, and contains other external works as well.


This project contained everything I've done in 2020. Its codename is Project_Squirrel.

Private files

Many of the programs and custom files I made are not shared publicly, due to leaks and unfortunate events that made me lose motivation to continue releasing them. However, I still share some of them with friends and people who support me, as well as people who are willing to do the effort of learning how to make mods and need some help.
