|Summary||08071: czeroize: [possible] Graphics start messing up at number 50.|
Here is a video that I made showing the graphics issue on the countdown. I had to start the recording before it get to 50.
I already know there is no dump of the czeroize.pro. Is this the issue? Should be flag yellow?

The graphics malfunction you mentioned is documented in the MAMEINFO.dat file and is expected. Whether or not it is correct behaviour from the original cassette load on original hardware, I'm not 100% sure.
- The tape loading counter starts at 142 and the graphics messed up at 50, because some data are loaded into the character/sprite generator RAM area.
The .pro file is the protection dongle which has not been dumped. There is simulation in place at this time until such a dongle is found.
As documented in the src\mame\machine\decocass.cpp file:
