What and why

Mario Kart World on the iPhone now rests on three independent lines that all landed in the same memory design, and two of them have had no place in this project's README at all: both lived only in their own forks. This adds a short Game bring-ups by the community section for them beside the launcher projects, so their work is credited where players and contributors look first:

• kartnative: the sparse texture checks, first-sample terrain tiles and the mem_map_limit memory plan behind the MKW memory settings at hand.
• plumber-racer-2: MKW 1.0.0 on iPhone and Mac from nxnative itself, with a full tutorial for players and the file-backed memory recipe; a whole cup on an iPhone 18 Pro in LiveContainer at about 3.9 GB.

#1252 / #1383 (sn0wst0rm) carry the in-repo form of the 1.8.0 work and are not duplicated here; this section lists separate projects only.

Docs changed: README.md, one new section, two entries.

Co-author credit:

• kartnative's settings carry pahorema's measured values.
• plumber-racer-2's Makefile/memory recipe is cheemu21's; its tutorial and touch controls link from their repo.
• sn0wst0rm's PR family gets the note numbers that make their session evidence cross-reference this README's three lines.

Checked

This is a README-only change, so only the docs check applies.

• Tests: README only, no host or tool change, so no check run (python3 dm/tools/tests/test_docs.py passes)

Front ends

None: no front end has to act on this.

Docs

• The finding is in its game note or its docs/reference/<subsystem>.md entry, and python3 dm/tools/docs_symptoms.py was run (the symptom index). Not applicable: a README-only change is not a finding
• A chain tool changed: dmsh_chain.py --header was run and dm/gfx/nvn/dmsh_chain.h is part of the change. Not applicable: no chain tool changed
• No game files, keys or data extracted from a game in the change or the attachments
