Someone in the ngb leaderboards made the suggestion that modded original xbox runs be allowed for submissions.

Since the og xbox hard disk does have a limited life span and you need it to play the game, yes. You need to mod the xbox to install a replacement hard disk.

Modded runs are allowed from games that are installed on the hd. The main thought for this post was just plain ng04 but extends to the hurricane pack. The og xbox will still fall behind xb360 because framerate slowdowns during effect heavy fights (especially during Emperor phase 1).

Update, a modded xbox is the only way to play the Hurricane Pack on og console. So no change here. Currently Xemu has FPS stutter issues with transparency effects but it's still playable.
