As discused on the Forum thread the 100% category has been changed to All Bosses, this better represents a completionist playtrough of the game

PS1 Runs on emulator now must use duckstation, the advantages include:

• With the set settings, it runs as close as possible with the console version
• Has features that allow for easier validation of runs and keeps an even playing field
• No issues, ePSXe emulator was having issues for some runners

Stronger and better thought rules gives us a better look and to the community as a whole. An even playing field might attract runners otherwise not interested.
