# MEGA65 Programming Playground
This is a playground for testing programming on the [MEGA65](https://mega65.org) 8-bit computer.
## Rust using llvm-mos
**Update**: _See the [`mos-hardware`](https://github.com/mlund/mos-hardware) crate for using Rust on C64 inspired computers!_
Amazingly, most core Rust features (`no_std` only) seem to work, including iterators and functional style
programming.
The `hello_rust` directory contains a simple example that compiles to a C64 `.prg` using
[llvm-mos](https://llvm-mos.org) from wrapped Rust code. It requires a working
Rust installation and the [llvm-mos-sdk](https://github.com/llvm-mos/llvm-mos-sdk#getting-started).
Compile and run on MEGA65 in c64 mode with:
~~~ bash
cd hello_rust
make
make run # emulate in xemu
~~~
### Things to do:
- [x] Added convenience `peek` and `poke`
- [x] Begin mega66 rust module with hardware registers (see e.g. KickC headers)
- [ ] Inline assembler? `core::arch::asm` seem to work but unknown upcodes
- [ ] Start in MEGA65 mode
- [ ] Wrap [mega65-libc](https://github.com/MEGA65/mega65-libc) to Rust?
- Build
- [ ] Use cargo
- [ ] Avoid c wrapper

### Why?
Because I like MEGA65 and I like Rust.
