The prototype is running Solstice in the NES. The workshop video shows cartridge insertion and the game on the monitor. One final hole-alignment adjustment remains before the next board order, followed by further fit, compatibility and reliability tests.

FROM THE WORKBENCH
Earlier photos, revisions and lessons from the build.
The purple connector board and green printed tray assembled in the open console, with a cartridge seated in the tray.

An unwanted short in an earlier PCB led to a revised layout. The corrected files passed the design and copper checks before new boards were ordered. The October 12 update above shows the later working prototype.
Read the board revision update →The current design uses a fixed support deck with side guides and board retention. The eject sled and spacer sets from early exploration are not part of this revision.

Blinking Light Win by Arcade Works inspired this independent replacement connector and loading tray, with original board routing. This project is not affiliated with or endorsed by Arcade Works or Nintendo.
