A few that were listed:

Hellraiser - Based on Nightmare on Elm Street
Bond, Thunderball - Based on Metal Gear
Duck Hunt - Halloween Edition
Ninja Gaiden - New Dialogue
Doug - Based on Robot Gyromite
Deadpool Taco Time - Based on one of his comic covers and Burger Time
Joker game - Based on Punisher

And a few more

Also ,haven’t done artwork for it yet, but Alien Syndrome would be a good Resident Evil 2 hack, with Leon and Claire as the 2 playable characters.
