That's really cool! Although extremely niche of course, but I'm happy to merge this.

Not worth implementing the init/deinit functions? Might maximize compatibility to return 0 from init, at least.

What else other than your test program uses it? :)

Only similar homebrew programs. Afaik, it was never used by any official program😀

To fix the build, you'll have to add the new file to the UWP vcprojs and also libretro/common.makefile. When it's green, I'll merge.

Let me know if I should take care of it instead.

I don't know if they receive any parameter, they are not documented

[hrydgard]

OK, I think we can just skip them then.

You can try decompiling the [decrypted] official prx (ie. sircs.prx) file using pspdecompiler to see whether the init syscall took any argument (ie. using a0/a1 register at the start of the subroutine) or not.

@Florin9doi
I'm personally shocked to know there's an IR port in PSPs (I don't think my PSP Go possesses one). So you're saying this library is official, but no games have used it? Then how do we know of its existence? Where does said sircs.prx come from? Which SDK was it introduced in? So many mysteries...

Only PSP1000 (fat) have infrared, this library was known since 2005 and is still present in latest firmware.
