If your converted file still doesn't show up in-game, check these common issues:
| Step | Tool | Download | |------|------|----------| | GME → NSF | gme_extract | Game Music Emu tools | | NSF → MIDI | nsf2midi | Zophar's Domain | | MIDI → MCR | midi2mcr.py | GitHub - midi2mml | | MCR Player | MCRPlay | MSX MCR Player |
A raw GME extract usually contains a header block identifying the Garmin device ID, followed by a series of waypoint records. Each record is 114 bytes long (in older formats) or variable in XML-style GPX. The critical takeaway is that GME prioritizes —storing coordinates to 1/10,000th of a minute—but lacks rendering instructions (colors, line thickness, transparency).
The .MCR extension is a "raw" memory card image used by nearly all PlayStation 1 emulators. These files are exactly 131,072 bytes
