 ## Library & Tooling Updates

+
+Just what everyone's always wanted, [Rust on the Sony PSP][rust-psp]! 😆
+
+This project is a port and improvement of the unofficial C/C++ PSPSDK from
+2005 It does not require a custom GCC toolchain to be installed. Only Rust
+nightly and a cargo subcommand.
+
+The psp crate provides a `psp::sys` submodule that houses the entire Sony PSP
+API. We are working to have theseinterfaces merged into the libc crate.
+The PSP unfortunately uses non-standard dynamic linking,
+(and some libraries are statically linked!), so function definitions
+marked extern are not enough. Eventually we will wrap this sys lib with a more
+rust-friendly library.
+
+Rather than patching LLVM or rustc, the rust-psp team has also merged a
+`mipsel-sony-psp` target upstream, and published cargo-psp. This is a subcommand
+that works exactly like cargo build, except it also builds the crate into a
+PSP-specific executable format called `PRX` and packages that into an
+`EBOOT.PBP`, the standard format for a PSP Homebrew.
+
+The crate has reached full user-mode parity with the unofficial C/C++ SDK.
+Kernel-mode support still needs to be worked on. Aside from library
+imports, there is also support for PSP-specific custom assembly instructions
+via the `vfpu_asm!` macro, with no need for a custom compiler toolchain.
+There is also optional `embedded-graphics` support and a function to benchmark
+or time your code.
+
+The next major milestone for rust-psp is std support.
+If you are interested in helping out, please feel free to join the rust-psp
+channel in the [PSP Homebrew discord server](https://discord.gg/WY8XhDG).
