设置
-
安装 rust >=1.59（或者启用 nightly/feature(destructuring_assignment)）
-
克隆仓库~
-
进入仓库
-
对于 bevy 和快速编译，直到单独的 crate，需要以下内容
sudo apt-get install g++ pkg-config libx11-dev libasound2-dev libudev-dev sudo apt-get install libwayland-dev libxkbcommon-dev sudo apt install mesa-vulkan-drivers sudo apt install lld sudo apt install clang cargo install -f cargo-binutils rustup component add llvm-tools-preview -
有关具体说明，请参阅bevy 书籍
-
此安装适用于带有 nvidia gtx 的 ubuntu 笔记本。我相信其中一些是不必要的。
-
为了使用默认稳定的 rust 和 g++/默认链接器，
-
您可能需要修改或删除
./.cargo/config.toml -
在发布时，您必须在
Cargo.toml中禁用bevy的 'dynamic' 功能 -
cargo run
操作码
CHIP-8 有 35 个操作码，都是两个字节长，以大端存储。
符号表
操作码表中的操作码列中的符号可以解释如下
| 符号 | 说明 |
|---|---|
| NNN | 地址 |
| KK | 8 位常数 |
| N | 4 位常数 |
| X | 4 位寄存器标识符 |
| Y | 4 位寄存器标识符 |
| PC | 程序计数器 |
| I | 16 位寄存器（用于内存地址）（类似于空指针） |
| VN | 16 个可用变量之一。N 可以是 0 到 F（十六进制） |
操作码表
下表列出了 35 个 CHIP-8 操作码的十六进制表示。
在这些操作码中，1/35 已在 chip 中实现（表情符号表示实现状态。）
| Implemented | Opcode | Explanation |
| ----------- | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 🌱 | 0000 | Returns the program. |
| | 00E0 | Clears the screen. |
| | 00EE | Returns from a subroutine. |
| | 0NNN | Calls RCA 1802 program at address NNN. Not necessary for most ROMs. |
| | 1NNN | Jumps to address NNN. |
| | 2NNN | Calls subroutine at NNN. |
| | 3XNN | Skips the next instruction if VX equals NN. |
| | 4XNN | Skips the next instruction if VX doesn't equal NN. |
| | 5XY0 | Skips the next instruction if VX equals VY. |
| | 6XNN | Sets VX to NN. |
| | 7XNN | Adds NN to VX. |
| | 8XY0 | Sets VX to the value of VY. |
| | 8XY1 | Sets VX to VX or VY. |
| | 8XY2 | Sets VX to VX and VY. |
| | 8XY3 | Sets VX to VX xor VY. |
| 🌱 | 8XY4 | Adds VY to VX. VF is set to 1 when there's a carry, and to 0 when there isn't. |
| | 8XY5 | VY is subtracted from VX. VF is set to 0 when there's a borrow, and 1 when there isn't. |
| | 8XY6 | Shifts VX right by one. VF is set to the value of the least significant bit of VX before the shift. |
| | 8XY7 | Sets VX to VY minus VX. VF is set to 0 when there's a borrow, and 1 when there isn't. |
| | 8XYE | Shifts VX left by one. VF is set to the value of the most significant bit of VX before the shift. |
| | 9XY0 | Skips the next instruction if VX doesn't equal VY. |
| | ANNN | Sets I to the address NNN. |
| | BNNN | Jumps to the address NNN plus V0. |
| | CXNN | Sets VX to the result of a bitwise and operation on a random number and NN. |
| | DXYN | Sprites stored in memory at location in index register (I), 8bits wide. Wraps around the screen. If when drawn, clears a pixel, register VF is set to 1 otherwise it is zero. All drawing is XOR drawing (i.e. | it toggles the screen pixels). Sprites are drawn starting at position VX, VY. N is the number of 8bit rows that need to be drawn. If N is greater than 1, second line continues at position VX, VY+1, and so on. |
| | EX9E | Skips the next instruction if the key stored in VX is pressed. |
| | EXA1 | Skips the next instruction if the key stored in VX isn't pressed. |
| | FX07 | Sets VX to the value of the delay timer. |
| | FX0A | A key press is awaited, and then stored in VX. |
| | FX15 | Sets the delay timer to VX. |
| | FX18 | Sets the sound timer to VX. |
| | FX1E | Adds VX to I.</sup> |
| | FX29 | Sets I to the location of the sprite for the character in VX. Characters 0-F (in hexadecimal) are represented by a 4x5 font. |
| | FX33 | Stores the Binary-coded decimal representation of VX, with the most significant of three digits at the address in I, the middle digit at I plus 1, and the least significant digit at I plus 2. (In other | words, take the decimal representation of VX, place the hundreds digit in memory at location in I, the tens digit at location I+1, and the ones digit at location I+2.) |
| | FX55 | Stores V0 to VX in memory starting at address I.</sup> |
| | FX65 | Fills V0 to VX with values from memory starting at address I.</sup> |
| 🌱 | _ | Panic. |

安装
由于程序以源代码形式提供，因此您需要将其编译到目标平台。因此，您需要安装一个完全工作的 Rust。一旦程序编译完成，您就可以在命令提示符下运行它，而无需安装。有关使用说明，请参阅下一节。
Rust Nightly 开发
此功能为实验性，需要夜间渠道。请参阅此处 此处夜间必须包含：rls, rust-src, rust-analysis有时夜间无法构建这些组件。请在此处查看最新状态：此处或在此处查看：此处例如，在2021-01-10，rls在夜间最后一次构建是在2021-12-05，因此："rust-client.channel": "nightly-2021-12-05",
用法
