How to Use dnSpy to Reverse Engineer Unity Games [ TUNIC ]

[@StephenChapman]

Always make a backup of your files before you modify them! Oh, and brush your teeth twice a day and wear deodorant! :D

[@dyonis5143]

Where can i download this Tunic demo it's not available on steam anymore ? I like the game and a good one to test on :)

[@StephenChapman]

@@dyonis5143 You'll unfortunately have to wait until the next time they make the demo available again. But there are lots of Unity game demos on Steam to practice with! Steam lets you filter by games with demos, so it's easy to find them. =)

Hello sir, can you make a video on assassin's creed odyssey hack with cheat engine 🙏

[@Bloopblop1]

Be amazing if you can show us how to code the main addresses and offsets in c++ or C# that way i can make hacks that my friends can use be amazing love your explanation ❤️

[@yorzengaming]

Funny when you explained some stuff about "Door" class someone was actually knocking on your door :D

[@Fligger]

Awesome Introduction into dnSpy! The screen layout is perfect! Nice to see some new videos. :)

[@DrGold-ks1mp]

Super easy to understand and helpful! Cheat Engine is nice, but it's even cooler to just edit the code of the game. Excellent presentation as well, I really like this new setup, showing the magnified points of interest of the game. Fantastic work, Stephen

[@Cryptonat]

Is there a way to use dnSpy in conjunction with Cheat Engine to find the method in memory for making cheats? If so, I'd love to see some sort of tutorial or information for that.

[@StephenChapman]

Absolutely! Chris over at Cheat The Game did a video showing a good technique for that: kzbin.info/www/bejne/kIPboJyjoLiWqZI You could also use the Mono Dissector in CE itself. There is a LOT that has been updated with it since I did this video, but I give a basic intro to it here: kzbin.info/www/bejne/j4rTnWeNfdWWiZY

[@Cryptonat]

@@StephenChapman Awesome! Thanks Stephen. I'll check them out.

[@anjat0]

would you possibly be able to show a Unity game that uses IL2CPP? I'm trying to figure out The Last Stand Aftermath but when I think something could work, either nothing happens or the game crashes. I currently have been able to make an infinite health and infinite ammo AOB script but I'm looking to create a DLL injection and try different things using mono dissector / .NET info

[@IllIl]

Great video! Definitely going to try this out on some Unity games. In reference to 17:20 it could be cool to see your full approach including all mistakes and the entire figuring out process. I learn a lot from seeing someone's problem solving process. Thanks for the video!

[@niravukani1371]

Hello sir, Hope you are doing well. I have one question. Can we reverse engineering IL2CPP build games? If yes please let me know how to do.

[@invincibleHunter]

whenever i put dll in the dnspy it loads as pe what should i do?

[@JasonPegasus]

do you know what i should to do if theres not "managed" folder?

Saved my life in a CTF, man. Thank you so much!

[@perguto]

Where did you get the Mono version of Tunic? My version seems to be compiled via il2cpp

[@StephenChapman]

Yeah, the demo version was what I used (since that's all that was out when I made the video). While you can still use dnSpy for modding IL2CPP binaries, it's pretty messy to do and has a fairly high barrier to entry. So instead of dnSpy, Cheat Engine's IL2CPP features are recommended. The tradeoff is that you will end up with a cheat table for use with Cheat Engine each time you play the game as opposed to a patched DLL, but something's better than nothing!

[@StephenChapman]

@@user-pv4vi6fg2w They could be doing any number of things. If it's browser-based, then there's a whole world of server connectivity you're not going to see with Cheat Engine. You can use a web proxy like Fiddler to MITM data, or a traffic monitor like Wireshark to deeply inspect/craft packets. You could try a cursory view of the game's API endpoints via Chrome's devtools -> Network tab -> Toggle XHR and see what pops up as you play. Those will be requests/responses to/from servers (but that includes everything, like social media sites or whatever else they bake into their game/page). You can potentially glean a lot about the approach they're using just by the name of the endpoints they use. They might have custom integrity checks implemented that makes it easy to see when you've done something to artificially bloat your score. Consider a different approach than what you're doing and see what happens. Maybe your score contains an illegal number (like ending in 5 if it's not possible to have a score ending with that number because all values are even). It could literally be anything. Anyway, if this is all unfamiliar territory that I'm mentioning, then I would expect to spend many months/years researching and getting good at it. It's a completely separate skill from everything you do with Cheat Engine, but a very good one to have in your toolkit if you're interested enough in it.

[@StephenChapman]

@@user-pv4vi6fg2w They can't detect applications due to browser sandboxing (if you're actually playing in a Chromium-based browser, Firefox, etc.). It sounds like timing/session/window focus integrity implementations in JS, possibly obfuscated.

This doesn’t have anything to do with dnspy but with Minecraft. How do I make an AOB script that I can turn on or off or just turn on using a pointer with a set aob value. I can’t check the cheat or it locks my location with moving aob value. I want to be able to put the values I want in each cheat aob script so that it doesn’t lock me. I found someone that found a way to teleport to the places they’ve been and found aob value using cheat engine but they didn’t find the pointer. Someone made a cheat engine table with the xyz cords on it also with the pointer so I backup the aob values for it, then I went to another spot and pasted the data back in and it worked and send me back where I backup the aob values of 66 bytes. What I’m asking in short is to make an aob script that injects 66 bytes of data from the pointers location?

[@furryfan87243]

So could this be used to extract GameCube models and levels from an ISO file?

[@djsvrlaivwfofj]

@Stephen Chapman Some unity games do not have a managed folder or asssembly-csharp.dll in its folders, but cheat engines mono features still show them loaded into the game, how do we find and edit those with dnspy?

Since TUNIC SaveGame has a lot of lines with a pair (nave|value) for a lot of elements, how can dnSpy be used to find chests? I had seen 243 chests by now and not sure (after 13 full passes on the game) if are any more. By 'find' i mean two basic things: 1.- Know if an specific chest name 'chest open #' (that not yet appears on the SaveGame) really exists on the game 2.- If it is possible, where on the map is that chest (firstly i love to find them on the map by myself) Just to start as an example of one chest i can not yet find: 'chest open 1009' ... from 1008 it jumps to 1010. Also there are other 'elements' on the SaveGame that i can not find inside the game, they appear on the SaveGame with a value of 0 (not finded/used), some has DEMO as part of the name, others has 'ladder', etc., are things that may be on the game but i can not reach/find. How all this stuff can be found with dnSpy? Any help is wellcome, thanks in advance. P.D.: I hope you know that the iin-game menu optios has two optios to activate no damage recieved and no stamina lost.

I tried to update unity mono source code from 2019.2.1-mbe to 2019.2.19 with Git, but when I wrote umpatcher 2019.2.19 f93c5973976e4bec5e769a31a73f00003f0a32dc "D:\GitRep\mono" "D:\GitRep\dnSpy-Unity-mono" it says that it's Copying files from D:\GitRep\mono to D:\GitRep\dnSpy-Unity-mono\unity-2019.2.19, but nothing happens, I checked it in Task Manager. It just stays still and says Copying files forever. How to fix that?

Subtracting 1 from 0 on something like that wouldn't crash the game, but instead of deleting you should use a ternary condition. Item.Quantity = (quantity - 1 < 0) ? 0 : quantity - 1
