Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

PS1 Programming Course with MIPS Assembly and C
PSn00bSDK maintainer here. Unfortunately the project cannot really be considered clean room; the original versions of most libraries contained code that was either lifted straight from Psy-Q disassemblies or heavily inspired by them. I have since rewritten pretty much all of it (with the exception of the GTE library which still has some Sony code) using only Psy-Q API documentation as a reference, but the "ship of Theseus" nature of the rewrite makes it hard to argue that it is a clean and legally safe project.
On the flip side, there are plenty of other open source PS1 SDK options that have been written from scratch, do not reimplement the same API as Psy-Q and can thus be considered clean for the most part. Here's a few of them:

PS1 Programming Course with MIPS Assembly and C
There are homebrew tools that can be installed on a PS1 memory card [1] and allow for executables to be loaded from a host machine into RAM through the serial port on the back of the console, in a similar way to what Sony's official Net Yaroze loader did back in the day. These tools can also use undocumented CD-ROM drive commands to disable region checks without the need for a modchip, provide semihosting (host filesystem access) and so on.
On the PS2 it's slightly more complicated, as there is no way to launch the "native" PS1 backwards compatibility mode other than to use a modchip (or firmware mod on some models) and burn the executable onto a disc; the serial port is not exposed either, making debugging much harder. It can still be done, but it's much easier to just use an actual PS1.
