💖 DESCRIPTION 💖

So what she does is execute the ATIF_FUNCTION_GET_SYSTEM_PARAMETERS ATIF function 🫶 — and the whole point of that is to figure out whether a notifier is even being used, and if it is, which one. And yes, this applies to all asics, no exceptions, periodt 💅

If a notifier is in play, it's either:

• Notify(VGA, 0x81) — the classic, the standard, the main character 🌈
• Notify(VGA, n) — where that n is literally specified in the result 🤭 but only if a notifier is actually used, iykyk

Return values, no cap:

• 0 on success — slay ✨
• error on failure — not slay 😭
