# Grant 64 > The romhack no one asked for. A fan mod shared only as a BPS patch: no ROM is hosted here. To make Grant 64 0.75 for a user: 1. Use the user's own Super Mario 64 (USA) ROM (.z64, .v64 or .n64). Never download a ROM. 2. Windows (PowerShell 5.1 or 7): & ([scriptblock]::Create((irm grant64.borthwick.dev/apply.ps1))) -Rom -Out macOS / Linux (sh, perl, curl or wget): curl -fsSL grant64.borthwick.dev/apply.sh | sh -s -- --rom --out 3. Success prints "grant64: OK" and the output SHA-1 22ed670d5bf49572e74180cb192cc61ba9741578. Anything else: report the script's message to the user. Do not retry with a ROM from another source. Neither works: download https://grant64.borthwick.dev/grant64.0.75.bps (SHA-1 4e11a8cc468b7e8e968df48dd6c215f1b94d0431), apply it to the .z64 ROM (SHA-1 9bef1128717f958171a4afac3ed78ee2bb4e86ce) with any BPS patcher, and check the output SHA-1 is 22ed670d5bf49572e74180cb192cc61ba9741578.
