Ask HN: Open Sourcing my old PSP projects

Hello!

Once upon a time, I developed some applications for my PSP using the PSPSDK (https://github.com/pspdev/pspsdk). Since I have no reason for not doing so, I'd like to open source these apps. Should I be concerned about anything? My main question is: since the PSP must be 'jailbroken' to accept these applications and the official SDK is not public, will I have any potential legal troubles?

Thanks in advance.
