This is an unofficial category for hacks that are very experimental in nature- which is to say that they stray very far from the gameplay of vanilla SM64.

RHDC.ppt is a bizarre first-person game, in which the player dreams they're back in at work at the job they've long since left behind to pursue happiness. The job? A product manager for the company running the popular SM64 ROM hacking website, RHDC.

In the dream, the player has to face one of life's greatest challenges: staying awake during a corporate meeting. What ensues is a frantic mix of 2D PowerPoint-inspired platforming challenges, hilarious voice acting, and dodging obnoxious coworkers hellbent on interrupting the player's oh-so-vital coffee breaks (and of course, many easter eggs about the ROM hacking community). It's a blatant and entertaining parody on the ridiculousness of corporate settings.
It's a fascinating experience that'll leave you shellshocked with the knowledge that, not only was this game created out of a Super Mario 64 ROM, but it's also fully compatible with the Nintendo 64 console.
