TLCS-900/H prefetch instruction queue test
Download ROM + source code

This is a small test ROM I wrote that might be of interest to someone writing a TLCS-900/H emulator. It performs a few tests that relies on a correct implementation of the prefetching mechanism of the TLCS-900/h and prints the results on the screen.

Mednafen and NeoPop fail on all of these tests. I haven't tried MESS.
On a real NGPC the tests all pass (of course), as can be seen here:
