The game not showing the move in the display (even though the manual says it does), it doesn't look like it's an emulation bug. You can see the same thing happening here:


It works fine when setting it to auto mode(computer plays against itself), also shown in the video linked by Mark 1.
I don't know where to obtain last move info, maybe somewhere in the RAM.

Plextor: did you have sound on? It's probably asking a question and waiting for your yes/no answer.
