VMWare Fusion allows you to run Windows 11 for arm on an Apple Silicon Mac and it has a free version for personal use that will be suitable for most people wanting to run Rumen8. As there is now a simplified setup process that downloads and installs Windows this is the recommended method to use Rumen8 on an Apple Silicon Mac. There is a video tutorial by Andrew Tsai
here that walks you through installing Fusion and Windows so you can then install and use Rumen8.
Once setup is complete you can then switch quickly back and forth between the Mac and Windows operating systems so is a very flexible setup.
Rumen8 is not native to the ARM architecture so must be run in an emulator provided by Windows 11. This means it will not run as quickly as on an Intel Mac.
