 # rvc - risc v in c
 
-An experimental RISC-V emulator written in plain C [0], with a focus on porting the result to a HLSL pixel shader.
+An experimental 32-bit [0] RISC-V emulator written in plain C [1], with a focus on porting the result to a HLSL pixel shader.
 
-[0] The elf loader ('elfy') is written in Rust, because I was too lazy to do it myself in C (Rust uses the 'elf' crate) and it doesn't need porting anyway.
+Mostly based on [takahirox/riscv-rust](https://github.com/takahirox/riscv-rust), which is a great resource for learning about RISC-V in general, aside from the [official specs](https://riscv.org/technical/specifications/) of course.
