[Solved] Tysila + REX prefix = invalid in i586 mode

Greetings,
I did the Bare Bones C# tutorial with success on an Ubuntu VM. I can successfully launch QEMU, and display text. I did some modifications, then Tysila told me the following:

Here's my batch file to compile the project and launch emulation:
I get the following output in the terminal:
What can I do to remove this error? Thanks!
