Get Qemu 
https://www.qemu.org/download/

Get ubuntu for risc v5 - I choose ubuntu-20.04.4-preinstalled-server-riscv64+unmatched.img
https://wiki.ubuntu.com/RISC-V
Uncompress with xz and give yourself some more space - I did this using a WSL 2 ubuntu shell as it was easier to use the tools from linux
xz -dk  ubuntu-20.04.4-preinstalled-server-riscv64+unmatched.img.xz
qemu-img resize -f raw ubuntu-20.04.4-preinstalled-server-riscv64+unmatched.img + 25G

Now you need some firmware and a kernel for risc V which can be downloaded from here

When submitting to the stores include this description on how to get an @sign so the testers at the store can use your app.

Do not check the box for passwords needed

```
Feel free to get a free @sign for testing. 
This can be done from the front screen clicking "SETUP NEW @SIGN" then "GENERATE FREE @SIGN".
Then click "pair", this will ask for an email and then send a code. 
Type in the code and save the Key File if you want to reuse the @sign. 
```
