DGRP (File Format)
The DGRP format is for creating dependency groups. It's one of the few formats that appears in all five Retro Studios games.
Format
The DGRP format is extremely simple; it's essentially just a list of resource dependencies (starting with a 32-bit count). The only difference between games is the resource ID length, and the addition of a RFRM Header in Tropical Freeze. A dependency is formatted like this:
| Offset | Size | Description |
|---|---|---|
| 0x0 | 4 | Resource type fourCC |
| 0x4 | Varies | Resource ID |
