EDIT: new version that also uses the AtariVox has been added.

Last night Nathan asked if I could create a 2600 sync pop program to aid in his creation of AtariAge YouTube videos. The program does a 10 second countdown starting at 9:59 seconds. When it hits 2:59 it displays a red square and generates a tone for a single frame. He included this mockup:

It continues to count down to 0:00 then restarts at 9:59. Format didn't matter, just the functionality, so I did a quick and dirty hack of Collect (changed the colors, blanked out playfield data, etc) as it was already set up to display the digits.

Nathan needed this because his capture software records the audio out-of-sync for some reason. Using SyncPop makes it easier to align the audio track with the video in post production. Usage is:

Start Audio and Video recording software
Load SyncPop in Stella, let it count down
Load game in Stella, record what you need
Once again load SyncPop in Stella, let it count down
End Audio and Video recording
Use the occurrence of the Red Square and Audio Tone at 2:59 to synchronize audio with video

Here's an updated version that also triggers the Pistol Shot sound effect on the AtariVox. The sound is triggered on 2:59, though due to how the AtariVox works it will last about 15 frames even though I send it a reset at 2:58.
