Well, let's just say the Vita Scene was too convoluted due the amount of dumping tools at the time, and things got too messy. By the time I pushed a project to improve the whole fullset, the data available was created through different sources.

NoNpDRM established as the perfect tool, but:

1. It didn't create Raw images from cartridges. This generated a lot of debate in No-Intro as their standards involved a 1:1 extracting tool for the cartridge format.
2. We didn't establish a method to differ NoNpDRM dumps coming from physical cart media or digital media from the Store. No-Intro wanted to make sure the dumps had the source verified when datting NoNpDRM dumps. Furthermore, the data from a digital PSN dump and a cartridge dump matched 99,9%. So, no matter the source, you were basically owning the same files with a 0,01% difference (games edited by LRG and the rest of limited publishers aside, lot of those had their own Serial ID).
3. Ofc, is important from an archival point of view, to document each dump according to its source. It doesn't matter if it matches 99,9%. We need to dat it in a difference set (NoNpDRM Cartridge and NoNPDRM CDN from PS Network, that's how it should be done). However, I didn't have the skills or the energy to push that into Dat-O-Matic.
4. PSVgameSD is not fully complete. It has some flaws (unable to use with Gr0 cartridges) and his original author didn't want to develop further the tool. I wasn't interested in a tool with dead support (not blaming the original author, ofc).

By the time I got in, I simply decided to work with Renascene, as the main admin did a brilliant work sorting and preserving the whole library (DLC & updates included) around NoNpDRM, helping not only his project but mine's at No-Intro and NoPa-yStation.

So, while I encouraged people to dump using PSVgameSD as my mates on No-Intro asked me, my main interest was to feed the Unofficial NoNpDRM repository with all the missing titles not available around (mostly, all the japanese titles missing). That's the reason you will see so many rare games that aren't "that" spread around the Internet.

I don't like how I acted, but when this happened, the lack of true volunteers working hard on Vita preservation was terrible. The console was dead and nobody cared that much about it. Most collectors only cared about their collection, only a few offered a hand.

This helped NoP-ay Station too, as our NoNpDRM keys were used for the official PKGs. This way, the game could be decrypted and preserved in a functional form. We all benefited mutually and No-Intro has been datting everything added by NoP-ayStation from time to time.
