goldberg_emulator VS design

For a lot of games you can simply copy out of Steamapps/common and run the exe and it'll run like a standalone copy.

For games that use steam features, you can drop in a steam emulator[0] to shim the API calls. I use this for when I want to run multiple versions of the base game with different mods.

Typically this works fine as long as there's no real Drm/anticheat (which is common in multi player games but rare for single player).

So this should allow you to clone parts of your library for your son to play (as well as consolidate your many accounts).

Goldberg steam emu

I highly recommend you go to https://gitlab.com/Mr_Goldberg/goldberg_emulator to find more information.

I tried to use Goldberg Emulator and I can't enable the overlay for it. How do I turn on the steam overlay because otherwise I won't be able to invite my friend?

What do you mean?

Why do you think you can't find Goldberg Steam emulator on Steam/Xbox/Playstation/Switch? (https://gitlab.com/Mr_Goldberg/goldberg_emulator)

Hint: it's used to play games without Steam DRM :)

Do you say that Valve's been a bully for years as well for trying to block Goldberg from Steam?

You would do the same if people made it easy to illegally distribute and use your products for free

And Nintendo is forced to do something to protect 3rd party studios/publishers as well

Any VPN will do (I used to use NeoRouter back in the day, but now I use OpenVPN to my cloud server or my home router), and you may be able to get some traction with Steam releases using Goldberg. https://gitlab.com/Mr_Goldberg/goldberg_emulator

I'm not gonna put the actual instructions for cracking here since that's already on the sites of the tools you'll be using. I will only link the tools here and the rest will be up to you. The main tools for cracking are going to be Steamless, and Goldberg emulator. These tools can be a bit tedious on their own but someone has graciously made an auto cracker that requires you to download the first 2 tools and then automates the process for you.

No clue, I'm using the Goldberg Steam Emulator. If you're asking what the Steam Emulator does, it allows the game to run without Steam installed, usually replaces the original steam(_api64/_api/client/client64).dll(s).

I have no idea about cracking games but try Goldberg Emulator. I use it for pirating DLCs but I think you can use it too. Also, its easy to use.

Hmm. I have a question. Would this work if the game had used say... the goldberg emulator for the steam drm bypass?

First of all, a quick rundown of what WASM is. It stands for Web Assembly. In essence, similar to how Java compiles down to a bytecode that is interpreted by a Java Virtual Machine, Web Assembly is a different bytecode interpreted by the browser. Many different languages can compile into WASM, and Javascript can interface with it like a module. In my case, I wrote a lot of the source code in Rust and compiled it down to a WASM module, then called into it from Javascript.

WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications. - https://webassembly.org

With WebAssembly we can compile our C++ codebase into a wasm module for the browser. So when you look at a SciChart.js chart you're actually seeing our C++ graphics engine wrapped for JavaScript.

I should add, however, that the unmentioned elephant in the room is V8 JIT (TurboFan), which simply doesn't handle irreducible control flow. While there are some valid theoretical arguments around the current arrangement in Wasm, looking at the history of the associated discussions makes it pretty obvious that having V8 support Wasm and generate fast code similar to what it can do for asm.js was an overriding concern in many cases. And Google straight up said that if Wasm has ICF, they will not bother supporting such cases, so it will be done by a much slower fallback:

https://github.com/WebAssembly/design/issues/796#issuecommen...

AFAIK no other Wasm implementation has the same constraint - the rest generally tend to desugar everything to jumps and then proceed from there. So this is, at least to some extent, yet another case of a large company effectively forcing an open standard to be more convenient for them specifically.

> Currently allocating more than ~300MB of memory is not reliable on Chrome on Android without resorting to Chrome-specific workarounds, nor in Safari on iOS.

That's about allocating CPU memory but the GPU memory situation is similar.

As far as I can tell (5 minutes of internet research) this was to allow easier compilation to JavaScript as a fallback in the days when WASM wasn't widely supported.

"Please add goto" issue has been open since 2016:

Most interesting comment:

> The upcoming Go 1.11 release will have experimental support for WebAssembly. This will include full support for all of Go's features, including goroutines, channels, etc. However, the performance of the generated WebAssembly is currently not that good.

> This is mainly because of the missing goto instruction. Without the goto instruction we had to resort to using a toplevel loop and jump table in every function. Using the relooper algorithm is not an option for us, because when switching between goroutines we need to be able to resume execution at different points of a function. The relooper can not help with this, only a goto instruction can.

> It is awesome that WebAssembly got to the point where it can support a language like Go. But to be truly the assembly of the web, WebAssembly should be equally powerful as other assembly languages. Go has an advanced compiler which is able to emit very efficient assembly for a number of other platforms. This is why I would like to argue that it is mainly a limitation of WebAssembly and not of the Go compiler that it is not possible to also use this compiler to emit efficient assembly for the web.

When I implemented a WASM compiler, the only source of float-based non-determinism I found was in the exact byte representation of NaN. Floating point math is deterministic. See https://webassembly.org/docs/faq/#why-is-there-no-fast-math-... and https://github.com/WebAssembly/design/blob/main/Nondetermini....

> To work with GC, you need some way to track if the GC'd object is accessible in WASM itself.

I've never heard of a GC with that kind of API. Usually any native code that holds a GC reference would either mark that reference as a root explicitly (eg. https://github.com/WebAssembly/design/issues/1459) or ensure that it can be traced from a parent object. Either way, this should prevent collection of the object. I agree that explicitly checking whether a GC'd object has been freed would not make any sense.

> The reason why you probably need a custom string type is so you can actually embed string literals without relying on interop with the environment.

WASM already has ways of embedding flat string data. This can be materialized into GC/heap objects at module startup. This must happen in some form anyway, as all GC-able objects must be registered with the GC upon creation, for them to be discoverable as candidates for collection.

Overall I still don't understand the issue. There is so much prior art for these patterns in native extensions for Python, PHP, Ruby, etc.

Giving you a buffer that grows is the allocation approach I am talking about. This is not how your OS works. Your OS itself works with an allocator that does a pretty good job making sure that your memory ends up not fragmented. Because WASM is in between, the OS is not in control of the memory, and instead the browser is. The browser implementation of "bring your own allocator" is cute but realistically just a waste of time for everybody who wants to deploy a wasm app because whatever allocator you bring is crippled by the overarching allocator of the browser messing everything up.

It seems like the vendors are recognizing this though, with firefox now having a discard function aparently!
