    I'm not new to programming, but I'm pretty new to the PSP modding scene. Are there docs or something someone could point me to? Even a decompiler would be good, so I can learn from how other people have made their plugins.
    I'm planning on making a f.lux or night-mode type plugin/filter, since there isn't one for the PSP yet, as far as I know. Thankfully, it sounds like an OK beginner project

    "even a decompiler"
    Because they are such common and simple programs?

    Anyway I don't know how many here would have written, or attempted to write, custom firmware plugins for the PSP to answer the question
    Looking around there are some open source ones
    https://github.com/NightStar3/zerovsh-patcher
    https://github.com/codestation/gclite
    Might be some more on
    https://wololo.net/talk/viewtopic.php?f=28&t=7407

    The custom firmwares themselves might also haves some indication as to what capabilities their APIs provide for access, assuming it is not an in place memory patch. This however might well vary between versions and flavours of custom firmware (there is a reason on the link above that version requirements are there).

    I don't know that the PSP has a measure of firmware driven colour correction -- brightness, volume,... sure but colour correction is likely a game by game affair. You might be able to step through the palette and make things a bit more yellow but eh.

    thanks for the links man those are a big help I'll check those out. And sorry for being unclear on exactly what the plugin I'd make would be. It wouldn't be a "filter" as in colour correction, it would just be a nearly-transparent yellow (#ffff00) solid colour overlay filling the screen. I know that wouldn't work perfectly, but anything else would be too ambitious for now, and with the help of an already-made brightness plugin (bright_v.03) I'll get a very similar effect to things like f.lux
