I actually went on a bit of a crusade in the past few days, trying to get the links for Palomino and the other 3 PSM games by Simone Serra (Atlas, ega, and Tribute). Palomino is a port of an Atari 2600 homebrew game that he released in 2013; Serra is seemo at AtariAge, but I was unfortunately unable to contact him through the AA forum.
As for other games not found in our list of links, sometimes, the developer was either unwilling or too busy to dig up the links to their PSM games. For some of them, PSM is old news, maybe even significantly unprofitable old news, and they'd rather put their time toward something else.
And then there are the developers who put their games in the PSM Store and then seemingly NEVER mentioned them anywhere on the Web. Not even on a Facebook account, Twitter account, personal blog, nothing. Examples, all with multiple PSM releases: Zhang Bo, Sun Pengfei, Z-D (it is really hard to track down anything when you only have 2 letters to work with!), B.P., Seth Eislund. I don't understand why you would go to the trouble of making many products available to buy but then put almost no effort into actually getting them bought.
By the way, it looks like we're ending with only four NPQA (Asia-region) games in the list. Since the known Asia-region dev IDs fit into a simple pattern, and the known NPQA numbers are all consecutive, I gave a shot at finding further NPQA games via trying out the next available numbers. No dice. The weird thing, though, is that it seems like there should be at least one more NPQA game: The Lost Kids was a (pricey) PSM release from XPEC Entertainment, based in Taiwan. Maybe they just got some weird dev ID, as is common in the other regions.
Anyway, we're really coming up to the end of PSM now. A reminder to all reading this: if you want to be able to keep playing your PSM games, do not switch accounts; do not remove or switch your memory card; do not trigger a database rebuild; do not go into Settings and choose to deactivate PSM (duh); do not restore a backup of a PSM game taken from a different PSV/PSTV system. All of these things will leave your system trying to reactivate PSM instead of running PSM games (or, in the case of the last one, trying to reauthorize that game for the different system to which you've restored the backup).
