Yeah, I did it back in 2006. It was only a demo. I think the first crash was due to me not getting certain things on even adresses. At least MESS somehow allowed for this back when. It crashed similarly on real hardware - Mantadoc made and tested as cartridge. I don't know why it has to do with the 4K selection, which I believe I never used. And yes, I tried to use the timer (9901), and Tursi was quick to alter his emulator to allow for that.
Two years later I did a TI blog on Sudoko with much better graphics. My active list as of now includes this and 21 other TI game projects. ๐
