- Clone the repository and it's submodules
git clone https://github.com/cakehonolulu/Risky --recurse-submodules- Install the required dependencies
Ubuntu/Debian:
sudo apt install build-essential gcc cmakeThis project uses the still-in-beta SDL3.
Since SDL3 builds still have not hit the main software repos, it's recommended to download the *.deb files for libsdl3 and libsdl3-dev and install them using:
sudo dpkg -i libsdl3.deb libsdl3-dev.debYou can find the deb files over at:
https://packages.debian.org/experimental/amd64/libsdl3-dev
Or if you prefer, you can build SDL3 from source and use that instead.
Execute the application, provided you use the more mature ImGui frontend; you'll be asked to create a RISC-V core; choose between the available base ISA/extensions and you're good to go.
Simply open a binary file containing the desired code to run and step through it.
