Sometimes it’s just educated guesswork.

Back in 2009, I picked up a copy of reverse engineered source code for the original PSP Photo Shot camera. Once I got it to actually compile (code formatting issues), I proceeded to read through what had already been reversed engineered, looking for the unknown/reserved variables.

And sure enough, when I went fiddling with a few supposedly reserved variables, I discovered that one of them triggered super slow exposure mode, basically poor man’s night vision!

I never had a chance to share those findings with the PSPHacks community at the time though, it wasn’t long after when their site got shut down ☹️
