Intellivision issues in BizHawk 2.8

[Winslinator]

Below I've noted two new issues I came across with Intellivision games in BizHawk 2.8 that I hadn't noticed in previous versions:

1. The AI for some games does not work correctly anymore:

• In Advanced Dungeons & Dragons: Cloudy Mountain, the AI only seems to chase the player horizontally or upwards, never downwards. As a result, this publication desyncs.
• In Space Battle, enemy squadrons spawning above the center will always move straight down and then straight left or right to the center in a rectilinear fashion. Squadrons spawning below the center will move left or right then get stuck. As a result, this publication desyncs.
• This submission for Sharp Shot desyncs too probably for the same reason.
• This issue most likely spans across other games I haven't mentioned as well.

2. When playing Advanced Dungeons & Dragons: Treasure of Tarmin, starting the game on certain frames will cause a major graphics glitch where random symbols appear at the top of the game window and the colors are all messed up. Loading this movie file will consistently produce the issue.

There don't seem to be any emulation changes to IntelliHawk between 2.4 and 2.7. Could you check 2.7?

Git bisect gives 0715db56086c294af96935193da35cceb7868225, which supposedly fixed something else...

Just tested it. None of the above issues above were present in 2.7.
