Hello my fellow readers. You probably noticed new engine patches that combine the functionality of 3v3 and 4v4  simul matches have been released for WinMUGEN and MUGEN 1.xx , but before proceeding to download them, you decide to know what makes these engine patches worth it. Well, you are in the right place to know what improvements my engine patches feature, so let us begin! (> Adjustable Simul Team Limit <) Main feature of my engine patches is the adjustable team limit,  which allow you to create simultaneous  matches with a maximum of 4 characters, so 4v2 or 3v4 matches are now possible in this patch version. (> Corrected Versus Screen <) Versus screen is now capable of showing the characters' potraits, while a maximum of 4 player names can be displayed, depending on the engine version.  (> Position Adjustment <) The other 4 characters will have their position X adjusted to their nearest partners instead of appearing on random locations when a n...

Oh, hello, readers. I never thought I would end up creating a blog entry for this, as the latter was not even in my plans, but well... I have created these engine patches, which allow you to create simul matches with a maximum of 4 characters instead of 2, while some additional code fixes were implemented in said patches. Engine Version Download Links: (> 1.00 - 4v4/3v3 Simul <)  or  (> 1.1b - EX+ Type <) Warning:  As expected from engine patches, unpredictable results could occur if known exploits are triggered in this program version, so keep it in mind while selecting your characters. I already know engine patches that implement this have already been released, but these patch versions also fixes some primary code defects. Additionally, the 1.1b patch version has been updated to make it compatible with one of the most known add-ons, MUGENHook. ... There is also a  WinMUGEN  patch version in case you need it.

Good evening, readers.  On this occassion, I have created a Reloader template from the EikiLoader.EX program for this engine version, that allows you to load a full version of your character while creating another instance of the process in a similar way to the Postman method. This exploit template uses the STBOF  vulnerability, which we have already talked about previously, to execute its shellcode. (> Download Here <) After downloading this exploit template, you will have to read the "ReadMe" text file to implement it in your character properly, before executing the Reloader shellcode.  You can use this to create your SuperNull/Reloader characters easily without the need of creating complex ROP chains to execute similar code. This is all for now. Have a nice day.

Good evening, friends. It has been a while since I have not talked about engine vulnerabilities, but I think this is the right time to start talking about this new vulnerability. This research was born from Nomi 's ideas about trying to overflow the ST filepath line in WinMUGEN, which motivated me to investigate said insight in M.U.G.E.N 1.00; a nd as expected, it is possible to perform a buffer overflow attack from there by creating a very long filepath string that overwrites the character loader's buffer region including the return address, allowing us to execute our ROP chain. This exploit can be used on both M.U.G.E.N 1.00 and 1.1b, but the main downside is not default-processing reversible, which currently restricts its use to SuperNull:Reloader characters only. (> Full information about this engine vulnerability can be found here . <) Note: Due to nature of the ROP exploit technique, do not expect this exploit to work on all the computers, so beware of it. Well, tha...

"Some things appear to be real, but how are you sure they actually exist?" Words provided by Einherjar. This is a SuperNull character, that is also a Proof-of-Concept, I have worked in collaboration with the author Nomi .  Einherjar uses the CTBOF engine vulnerability, which is not so used due to its ROP limitations, to load her shellcode in M.U.G.E.N 1.00.  Download link can be found either  here  or in Nomi's website. Caution: It may not work on some computers, due to the way the ROP technique works, so beware of that matter. It has been a very while since I have created a character like her, but well, this is all for now.

Good afternoon, friends. Hmm, I never thought I would be talking about this vulnerability again, but well, let us go straight to the point. As you can guess, this vulnerability also exists in M.U.G.E.N 1.00, but due to the NX Bit protection being active in the program, shellcodes cannot be directly executed, so it is required to use an exploit technique, known as Return-Oriented Programming , to circumvent said protection. I have recently made an exploit that takes advantage of such vulnerability, but as there are several pointer limitations to build a ROP chain that jumps the engine back to default processing, it is currently limited to SuperNull ~ Reloader characters. (> PoC can be downloaded here <) Note: As this exploit requires ROP chains to execute its shellcode, do not expect it to work on all the computers, so beware of it. Well, that is all for today, have a nice day.

Hello, friends. For this occassion, I have created my engine patch for WinMUGEN, which allows you to create simul matches with a maximum of 4 characters instead of 2, while several code fixes were m ade to improve the game experience. Download Here: (> Version 1.05S <) Warning:  As expected from engine patches, unpredictable results could occur if known exploits are triggered in this program version, so keep it in mind while selecting your characters. ... There is also a  1.00/1.1b  patch version in case you need them.

  Do you want to know how an engine exploit works in detail? Do you want to know more details about a character you like? Do you want to add your research into some articles?  If that is the case, we have this page for you to check out:  All the articles about characters, authors, and exploits can be found in this Wikia page, so you can get an idea about how they work in detail! Main articles have already been covered, but new content is yet to be created.  

  Hello again. It has been weeks since I have been working on this Cookie Clicker game adaptation for this engine version, so as not to kill any possible "expectation", some beta builds will be released in this post. (> VB0.02: Download Here <) Make sure to read the ReadMe text file before use Warning: This game adaptation can only be run on the Hi-Low Res version and is not intended to work as a playable character, so do not expect it to fight other enemies, as unpredictable results could occur.  Despite being in W.I.P state, current beta build link might be changed for the latest one, so stay tuned for new posts.

Hello friends. It has been a while since I do not post new content in my blog, but for this ocassion, I will be posting some development logs about this game adapation for M.U.G.E.N Engine: Cookie Clicker As you can guess, incremental type games like this one are virtually impossible to adapt in a fighting engine like M.U.G.E.N without the help of exploits, as the latter allows me to enable mouse support besides implementing some code patches for optimization purposes. Due to engine limitations, I will have to integrate new game mechanics to compensate, so you can have a unique and different experience when playing this game adaption. It is currently in W.I.P state, but it will eventually be released to the public after fine-tuning the last details, so stay tuned for new posts. Have a nice day.
