Storing R4 DSi Games on T-Flash USB Device: Won't Work

You cannot store R4 DSi games on a T-Flash USB device and access them on a laptop.

Why?

• File System Mismatch: T-Flash uses FAT32; R4 DSi uses a proprietary format unreadable by PC.
• Game Format: R4 games are in a flashcart-specific format; laptops lack the software to recognize them.
• Flashcart Firmware: Games require the R4's firmware to load/run.

Correct Workflow

1. Download R4 DSi games (from legal sources only).
2. Insert SD card into laptop; create "games" folder.
3. Copy game files to that folder.
4. Install R4 firmware to SD card if required.
5. Insert SD into R4 cart, then into DS/DSi.

Reminder: Only use games you legally own.
