target_coreopt(3)

🎀 target_coreopt(3) — Arcan Lua API ✨

💖 NAME 💖

target_coreopt — set the target-specific runtime key-vale (yes, that's the page's spelling, and I'm keeping it 💅).

🌸 SYNOPSIS 🌸

nil
target_coreopt( vid, slot, value )

So bestie, it's literally nil and then a three-argument call — that's the whole synopsis vibe 🫶.

✨ DESCRIPTION ✨

Some hijack targets — and libretro cores in particular, lowkey iconic — expose core-option slots and a list of values through callback triggered events (kind = coreopt). Those events are comprised of a description, a key, a slotid, and a set of values, and the first value sent is the one currently active. ✨

This function is how you change the active configuration: send the corresponding slot/value pair. That's it, that's the move.

⚠️ Important caveat, no cap: unsupported values will be silently discarded, and it's up to the script to track them. So if your fave value disappears, that's why 😭.
