Star Rod .mod patch files

Short answer

A Star Rod .mod file is a patch format produced by the Star Rod editor for Paper Mario on Nintendo 64, identified by the magic bytes `PMSR`. It applies to a Paper Mario ROM the same way any other patch does, and stores checksum data so it can confirm the correct base ROM.

What Star Rod .mod files are

Star Rod is a dedicated level and content editor for Paper Mario. It exports mods in its own container format rather than a general patch format, marked by the four bytes PMSR at the start of the file.

Applying a Star Rod mod

Load a Paper Mario N64 ROM in .z64 byte order along with the .mod file in the patcher. If the ROM does not match, check your byte order first, since Paper Mario dumps circulate in several.

Frequently asked questions
