ROM version
From Zodipedia
You can find different versions of a ROM. There are, for example, ROMs that are modified to run better on an emulator. Sometimes only one version of a game works with the emulator (in this case one of ZodTTD's emulators).
- To determine the version of your GBA ROMs, use GoodGBA (official download page) with GoodGUI (official download page). The version codes are explained here.
