Convert GDEMU SD Card to MODE

A utility to convert a GDEMU-formatted SD card to one suited for the MODE.

This utility will move, rename, and delete files on the target SD card in order to conform to MODE's requirements, including single-folder multi-disc support. Please do not run this program against a copy of your daily-use GDEMU SD card. Instead, use a copy or backup.

Note that this utility expects the target SD card to have been created with SD Card Maker for GDMenu.

Current Version

Convert GDEMU SD Card to MODE is currently at version 1.0.

Supported Features

Below is a specific list of the current features.

Support for both GDI and CDI disc image formats.
New DREAMCAST folder created in root of SD card.
All numbered folders (.e.g, 02, 03, etc.) renamed based on name.txt.
To take advantage of MODE's automatic disc-queueing abilities, multi-disc games are grouped in the same folder with all of their files renamed for proper alphanumeric sorting.
Invalid filename characters inherited from name.txt are automatically stripped and/or converted.
Folders that don't contain a valid game disc image are skipped.
GDMenu folder (01) ignored and deleted.
GDEMU.ini configuration file automatically deleted.
If no name.txt file is found, UNKNOWN X (where X is iterated over) is used as game's folder name.
