The error (0x37) is privileged action, this should not happen with
normal executables. I'd be happy to debug the binary if you sent it to
me.

Well, there are bugs in the emulation as you have noticed. Moreover a
full 64-bit user environment is not very common on Sparc so nobody has
been very interested in it except  me.

No, though that's in TODO. The problem IIRC is that the X11 keys are
translated to PC values before getting translated to Type 4 codes.
