How to try your own copy
- Use a disc image you own and check its release against the information above. An unspecified release is not confirmation that all releases work.
- Follow the local build guide in a documented Linux or Apple silicon macOS build environment. Keep the generated game build on your own machine.
- Record the project commit, device, browser and exact point reached. If something fails, use the troubleshooting guide before submitting an upstream issue.
