Python White Fin is a plugin that enables Cobra Blackfin compatibility on firmware versions 3.60 and above.

Some Technical Info Dump From The Author

While working on a packet logger for CMD56 (used in GameCube authentication), I encountered an interesting situation. Initially, my packet logger worked as expected, but unexpectedly, it caused issues with game cartridges’ authentication.

Here’s what happened: The Vita IO (input/output) system operates at a sluggish pace, and the Cobra Blackfin patch was designed to check if authentication took longer than 50,000 microseconds. If it did, authentication would fail. This was particularly relevant because the Blackfin component connects to the internet for game cartridge authentication, which inherently involves delays due to network communication.

Now, the twist: My custom packet logger code unintentionally slowed down the authentication process to the point where it triggered the same failure condition. To address this, I decided to revert Sony’s patch for Cobra Blackfin, allowing me to log the packets accurately.

The whole situation was too amusing to ignore, so I turned it into an actual plugin. Sometimes, even in the world of programming, humor finds its way!"
