I'm just wondering how real is to produce Win32 ARM binary with fasm for run on Surface RT ?

There are ARM PE examples in the fasmarm download. Try them and see what happens. My guess is the they won't work. For two reasons.

The current ARM PE format in fasmarm is designed for Win CE, and
The Surface RT requires signed binaries downloaded from the MS website.

Remember that Win RT is not an open system. Unless you get approval from MS then there is probably no chance to write your own code and get it running on an unmodified RT system.

alternative is by getting a developer license (free)

edit:it seems it works on the "Preview" version. also. i am not sure about that

hopcode, this is not about native win32 arm code. this is about Windows Store Apps. My point of interesting is fasm and win32 arm compilation.

I didn't see any hacks there that worked on the production Surface RT. The Surface RT lock-down seems to be very complete. I expect MS learned from the Apple jailbreaks and decided to make things more secure and allow less user control.

revolution, what's the problem to define SurfaceRT Win32 ARM PE format and sign with test cert ?

No problem that I know of, but that is only useful for one device. You couldn't post the binary code for others to use. You will still need to get MS to approve it to allow it for general use.

Do you know if the RT uses the same PE format as CE? Perhaps with a new identifier and version number?

RT is NT-based so I would expect it to look more like an NT PE header. Naturally the machine type would be set to ARM.
