NFL Instant Replay (CD-i)

NFL Instant Replay
Developer: Capitol Disc Interactive Publisher: Philips Media Platform: CD-i Digital Video Cartridge Released in US: 1995 This game has hidden development-related text.

To do: Document the June 15th, 1995 prototype.

NFL Instant Replay finally lets you play as the referee instead of the football players themselves. Can you correctly judge enough low-quality clips to make it to the Super Bowl?

Debugging Files

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Can this debug mode be reactivated in some way?

Three unused files can be found on the disc, all of which contain code and strings meant for a debugging mode. It would've been controlled using a keyboard and a CD-i dev kit.

cdi_replayd

The first, largest file is cdi_replayd, a debug version of the used file cdi_replay. Its contents can be sorted into three chunks.

Chunk 1 deals with the gameplay logic itself, though there's nothing noteworthy in it due to its simplicity.

Chunk 3 features the CD-i graphics editor/second chunk-esque strings ubiquitous among the debug files of CapDisc's games. It also contains the text of a memory editor made by 'VDS and JHO', present in a select few of their titles.

The third, smallest file is cdi_replayd_data, a debug version of the used file cdi_replay_data. The only change between the two is the addition of two KB of data near the middle/end of the former.
