I just wanted to share the controller I used to use for Bleem games exclusively until megavolt85 released Bleemshell making analog and L2, R2 and Select mapped to D-pad on games.
I got this controller in 2015 after reading Tom Charnock's article over at Dreamcast Junkyard reviewing these things. Sure they lack analog, and any VMU port or rumble, but it makes up with it for having a Saturn style 8-way D-pad which is really great for arcade games, fighters and emulators. They are referred to as the Game Heaven only. Nobody knows if that is the brand or what? The controller is really rare and only pops up from time to time on eBay. It is solidly built though and I love mine to death. It was discovered that they have the same shells as the Logic3 PSX style controllers, and they made many other colors so if you want to mix and match to customize one if you have it, it can be done.
Here is what one looks like compared to an official PSX pad.
