So here is some issues I found. I have found about 5 more that I need to look into more but they seem the same basic theme as these problems. So I wanted to go ahead and post:
Armored Encounter + Sub Chase (1980)(Philips)(EU-US)
Select game 1 (pressing 1 on keyboard)
The game will start with a 3 minute timer, do nothing and let the game clock run to 0
Notice the core seems to "crash", all lag frames after that and no way to continue,
Pressing "Power" doesn't reboot to a bootable state, have to reboot core
Bowling + Basketball
Press 1 to get to bowling, play and entire game, seems to crash, and need a reboot
Blockout + Breakdown (1981)(Philips)(EU-US)
Lot of sceanline looking issues
Also, hold enter, and the backgrounds start flashing rapidly, I don't think any of this should happen

Consmic Conflict (1980)(Philips)(US)
The center of the screen is flashing black and blue at 30hz. Footage of this game doesn't suggest this happens, but of course a 30fps youtube video wouldn't show that so I can't be 100% sure, but it's pretty bad looking
Great Wall Street Fortune Hunt, The (1983)(Philips)(EU-US)
The stock banners alternate with color and black every other frame. Again, since it is 30hz, footage doesn't necessairly prove the real game doesn't do this, but it seems likely this is a bug
Pinball (USA) (Proto)
This one is a just a prototype so I don't know that this is not game behavior, however the ball can go through the top wall of the screen. I mention it because I know previously there were collision detection issues, so didn't know if this was a potential problem like that
