I use it, and ship system images for it:

And here's me recentish-ly debugging an issue via it:

(Compile/test cycles are WAY easier there than copying files onto an sd card to test on actual hardware.)

There was a big-endian issue breaking r2d last year, but it also broke big endian mips and some other targets too, and it got fixed. The binary I built a few months ago was working fine for me with vanilla qemu git source? (I don't _think_ I had local changes?) I can try to build the version removed to check that...

Yes I should be better about pushing local patches upstream. For example, here's the kernel patch I use to run fdpic binaries under qemu:

https://landley.net/bin/mkroot/latest/linux-patches/0002-sh4-fdpic.patch

Which lets you enable the FDPIC loader on an mmu kernel, which is useful for testing j-core userspace under qemu.
