reko VS dnSpy

In the zip are 3 firmwares, NXP, PD and Scalar. NXP is the USB microcontroller that's used to update the scalar firmware, and PD is for USB-C stuff. The scalar firmware's name was 28MQ780_MSTAR_MST9W00V4_V3.3.0_0x12FBF031_shad4015bb_220317.bin, which already gave me a few more data points, specifically the chip that's used, the MStar MST9W00V4. Eventually I found this extremely annoying post which had the compiler used for the chip and this page telling me that my scalar's CPU architecture was proprietary, but based on OpenRisc. It turned out that the stars had aligned or something and there were no less than 3 people interested in this particular ISA in the last 3 weeks, because someone else had asked about it and apparently a niche disassembler added partial support for it.

Reko has the ambition of supporting decompilation of various processor architectures and executable file formats with minimal user intervention. For a complete list, see the supported binaries page.

For some examples of hand-written parsers in C#, take a look at my project https://github.com/reko. There is both a C and a Pascal parser, located at https://github.com/uxmal/reko/tree/master/src/Core/CLanguage and https://github.com/uxmal/reko/tree/master/src/Core/Pascal, respectively. DM me if you're curious, I be glad to tutor.

Protip: Use a debugger like dnSpy or Visual studio to trace the source of error, by stepping the program line by line. You can restart with dnSpy attached.

Download dnSpy, Open the file "assembly_valheim.dll", Select view and then Assembly Explorer, search for DLCMan class (if you have trouble there is a search tool in the top bar, doing so you'll find the whole class), went to the correct lines (50, 79, 97 even if for me it was actually 98), right click on edit method/class (might be better to use method) and change the " return false; " to " return true; ". After the process compile again and there you have it.

To inspect the code, I recommend dnSpy. https://github.com/dnSpy/dnSpy You want to run it on the Assembly-CSharp.dll file from _Data/Managed. Then you can view the source code. I searched the entire project for the word "pause" until I found something that looked relevant. Luckily, the code for this game is pretty well written and well laid out.

It's dnSpy.

Great question! The tool I used, DNSpy, has the ability to patch in opcodes. So I just put in the instructions needed as essentially assembly, and I did so by just writing bytes into the existing executable. The two I used were ldc.i4 to put an integer onto the stack, and then mul to multiply it with the existing value.

.NET is super easy to reverse, you don't need Ghidra, go try dnSpy, that should do the trick.

Code Creation. Unfortunately, I don't have more information on the code of the game. This is the part I need help with. I'm quite familiar with HTML, CSS, and Javascript, but haven't really touched C#. The best that I've managed is opening Kitchen.Common.dll and KitchenMode.dll in dnSpy (https://github.com/dnSpy/dnSpy) and looking at the class and struct names, recognizing that some of the contents of those dll files which start with C, like CAppliance, are components of entities in the game, and can be used to retrieve entities somehow. I have no idea how to use the classes, like GrabItems or CreateNewMesses. Who knows if either of those do anything? Oh, and making an item or appliance? No idea.
