Discuss this release on our Discord server!
Hello everyone! Sorry to keep you waiting since the holidays!
We have a few things cooked up for you in the not-so-distant future, but for now, we’d like to share something that will tide you over. We have a few “release candidate” PSP prototypes, builds that are near final but didn’t pass initial certification and needed a second version before being published. These prototypes were brought to you by Jehuty who had a treasure trove of almost 100 UMDs!
The games featured in this lot are all the ones that are confirmed to be different from anything released. These were verified using the same technology that helped us with Deluge, so we could confirm that these were all unique builds compared to the Redump set as of writing. The UMDs were dumped by site administrator Sazpaimon using PSP Filer v6.6 on the original hardware.
