No test called sceKernelDeleteHRTimerEvent. VerifyHRTimerDelete checks
it as FreeBSD's kevent EV_DELETE for the HR timer filter: EBADF on queue
0, ENOENT for a timer that was never added or is already deleted, only
the HR timer of an id removed while a regular timer of the same id stays,
and a fired timer deleted before it is collected no longer reported.

On PS5 firmware 13.60 sceKernelGetEventError returns 0x80020000 plus the
event's fflags in 32 bits for every non-zero fflags, including values
above 0xFFFF, where it used to throw.

FreeBSD 11 kqueue_scan (sys/kern/kern_event.c) re-inserts a reported
knote without EV_CLEAR or EV_DISPATCH at the tail of kq_head, and
knote_enqueue puts a knote that fires again at the tail as well, so the
next scan starts with the events that were not reported yet.
sceKernelWaitEqueue scanned the event list in place, so with num smaller
than the number of ready events the first ones were reported on every
call and the later ones starved. Each reported event that stays
registered now moves to the end of the list, in the order reported.
Undrained triggers queued without limit and AddEvent copied the whole queue, so a flip/vblank flood could exhaust the host heap while guest memory stayed free. Keep the armed event plus at most 64 queued events per registration, dropping the oldest queued event past the cap and keeping the latest payload; an AddEvent carrying more keeps the latest 64. Drained bursts report as before.
Return the event's data when EV_ERROR is set in its flags and 0 otherwise, as KytyPS5 does and as FreeBSD 11 kevent stores the errno of a failed change. A null event throws like the other accessors.
A user event added with sceKernelAddUserEvent stays triggered until it is
deleted. The collection loop kept re-emitting it until the caller's event
buffer was full, so a wait with num > 1 returned the same event num times.
Like kevent, each event is now reported at most once per call; distinct
queued completions of one event are still delivered in order.
(cherry picked from commit db28ebbb7f)
sceKernelGetEventId, sceKernelGetEventFilter, sceKernelGetEventFflags,
sceKernelGetEventData and sceKernelGetEventUserData return the matching
field of the KernelEvent filled by sceKernelWaitEqueue and throw on a
null event. sceKernelGetEventError still throws NotImplemented.
