Warning: This guide is for educational purposes. Modifying your Switch requires a patched unit (pre-Mariko) or a modchip. Online play with modified NSPs risks a console ban.
Each update NSP contains:
| Metric | Value | |--------|-------| | New floor generation time | ~0.4 sec (Switch OLED) | | Palette upgrade memory | 48 MB per run | | Crash rate (post-patch v6.1.2) | 0.03% over 10k runs |
Ironically, each new official patch also patches known entry points for cheats. For homebrew users, this means waiting for a sigpatch update before applying the latest NSP.
To install .NSP files (updates or DLC), your Switch must be modified. Standard retail Switches cannot run these files without modification.
