• Your own dump of Super Mario 64 (USA): .z64, .v64 or .n64. No ROM is hosted here and none will be.
• Windows: PowerShell, already built in. macOS and Linux: a terminal, already built in.

Open PowerShell in the folder with your ROM and paste:

irm grant64.borthwick.dev/apply.ps1 | iex

It finds your ROM, downloads the patch, checks every hash and writes grant64.0.75.z64 next to it.

& ([scriptblock]::Create((irm grant64.borthwick.dev/apply.ps1))) -Rom 'D:\roms\sm64.z64' -Out 'D:\roms\grant64.0.75.z64'

Open a terminal in the folder with your ROM and paste:

curl -fsSL grant64.borthwick.dev/apply.sh | sh

Same thing: it finds your ROM, checks everything and writes grant64.0.75.z64.

curl -fsSL grant64.borthwick.dev/apply.sh | sh -s -- --rom ~/roms/sm64.z64 --out ~/roms/grant64.0.75.z64
