feat: support external game launchers

Apparently the crashes were an artifact of a different thing, and don't actually happen under normal conditions

+# Jadeite Autopatcher
-- **3rd**: glb/sea/tw/kr/jp **v7.1.0+**, cn **v7.2.0+**
+### Current game support:
-- **SR**: os/cn **v1.6.0** (potentially unsafe, but no bans were reported since v1.1.0)
+- **3rd**: glb/sea/tw/kr/jp **v7.3.0+**, cn **v7.3.0+**
+- **SR**: os/cn **v2.0.0**\*
 
 You can expect newer versions to work immediately after release with the same jadeite binary if the version is specified with a + above.
 
-### Information
+**Note:** you can test the experimental version-independent patching method for SR. See [#37](https://codeberg.org/mkrsym1/jadeite/issues/37).
+
+**Note:** the Steam version of 3rd was reported to work, however I neither tested it nor intend to support it, so it might break at any time. Use at your own risk.
+
+## Information
 The anticheat the games use is fundamentally incompatible with Wine in multiple ways. This tool launches the game without it (`injector`) and imitates it's behaviour (`game_payload`).
 
 **Using third-party software (such as this tool) with the games violates their Terms of Service**. Therefore, **you may receive a ban**. No bans were ever reported with 3rd, however the legacy patch for SR did cause many. **Use at your own risk and only if you understand all the possible consequences**.
 
 **This is not a cheating tool**. Using it with Windows is not possible, and Windows support is not planned or intended in any way. However, as it does not perform any on-disk file modifications, you may reuse the same game install for Windows if you have a dual-boot setup.
 
-### Usage
+## Usage
-**Refer to [third-party launchers](#third-party-launchers)** for convenient usage. If you don't want to (or can't) use third-party launchers, continue reading the section below.

 **3rd-specific**: 
 - **Wine 8.21+ or [Wine-GE-Proton](https://github.com/GloriousEggroll/wine-ge-custom) is required to play videos. The game may show a black screen or crash on lower versions.** 
@@ -27,37 +32,44 @@ Manual usage instructions:
 - Run `./block_analytics.sh` from the archive to block the games from accessing analytics servers (you might have to do a `chmod +x block_analytics.sh` first). This will require superuser privileges 
 - Run `wine jadeite.exe 'Z:\wine\path\to\game.exe'`
 
-This tool is capable of starting the games from a different process. This may be useful for spoofing the parent process (SR is known to report it). Use `wine jadeite.exe 'Z:\wine\path\to\game.exe' 'Z:\wine\path\to\launcher.exe'`. `explorer.exe` is used as the default.
+Detailed command line interface reference: `jadeite.exe [game path] <launcher path> <game args...>`, where:
+- `game path` - Wine path to the game (required)
+- `launcher path` - Wine path to the launcher process (optional, default is `C:\Windows\explorer.exe`). The launcher process will be used to start the game. You can specify the path to the official launcher here. Specifying anything other than `explorer.exe` or the official launcher is not recommended. Specify `--` to skip this argument and use the default
+- `game args...` - arguments to pass to the game process (optional)
 
-To pass commandline arguments to the game, append them after the launcher path: `wine jadeite.exe 'Z:\wine\path\to\game.exe' 'Z:\wine\path\to\launcher.exe' -arg1 -arg2 -arg3`. To use the default launcher process, use `--`: `wine jadeite.exe 'Z:\wine\path\to\game.exe' -- -arg1 -arg2 -arg3`.
+Example command: `jadeite.exe 'Z:\path\to\game.exe' -- -screen-fullscreen 1`
 
-### Configuration
+## Configuration
 These environment variables can be used to configure the behaviour of the tool. Any value except empty string counts as set. `1` will be used in all examples.
 
+**Global**:
 - `WAIT_BEFORE_RESUME=1` - show a messagebox and wait for user input before resuming the game process. Useful on my side for debugging
 
-### Internals
+**SR-specific**:
-This tool consists of three parts: the main injector (`injector/src/exe.c`), the launcher payload (`injector/src/dll.c`) and the game payload (`game_payload`).
+- `BREAK_CRYPTCAT=1` - use the experimental patching method. See [#37](https://codeberg.org/mkrsym1/jadeite/issues/37) for details
 
-I am very bad at explaining, so just take a look at the source code. Maybe I'll write a detailed explanation in the future.
+## Internals and building
+To compile jadeite, you will need meson, mingw and nasm. You can probably install all three using your repository's package manager. Once all dependencies are installed, run `./build.sh` in this directory. The compiled files will be located in `./out`.
 
 A part of the source code is witheld (`game_payload/src/core.c`). This is a forced measure to make abuse more difficult. However, a precompiled blob is provided in the repo. `build.sh` will use it automatically.
 
-### Guildelines
+All source code except `core.c` is available in this repository. You can take look around.
+
+## Guildelines
 1. **Please don't share this project in public.** This might attract unnecessary attention from either the Game Company or the Anticheat Company
 2. **Please don't abuse this project for cheating.** We're just trying to play the games through Wine
