## controls

Keys are mapped according to mupen64plus defaults: https://mupen64plus.org/wiki/index.php/KeyboardSetup#2._Default_Key_Mappings_for_SDL-Input_Plugin. Xbox-style controllers also have a default mapping applied.

You can create you own mappings by running `./gopher64 --configure-input-profile my_profile`. You then bind that profile to a port: `./gopher64 --bind-input-profile my_profile --port 1`

In order to use a controller (for example, an Xbox controller), run `./gopher64 --list-controllers` to get a list of attached controllers, and then assign it by doing `./gopher64 --assign-controller <controller_number> --port 1`

## netplay

Gopher64 supports netplay (online play with others). It has a few public netplay servers. If you are interested in running a public netplay server, please let me know (open an issue or discussion, or contact me on Discord). You can also run the server (https://github.com/simple64/simple64-netplay-server) yourself on a LAN.

## portable mode

If you would like to keep all the game data in the same folder as executable, you just need to create a file called "portable.txt" in the same directory as the executable.

## goals

1. Performance. I want to be able to use this emulator on my laptop.
2. Easy to use.
3. Easy to work on. Dynamic recompilers perform well, but they are very hard to read and understand. This emulator will only have interpreters for the CPU and RSP. Additionally, it is completely written in Rust (besides Parallel-RDP), a modern programming language with a growing user base. I've tried to avoid the use of macros, which can reduce some repetitiveness in the code, but also reduce readability.

## building and usage

1. Install rust: https://www.rust-lang.org/tools/install
2. `git clone --recursive https://github.com/gopher64/gopher64.git`
3. `cd gopher64`
4. `cargo build --release`
5. `./target/release/gopher64 /path/to/rom.z64`
