Optical drive replacements

An optical drive replacement is a device that replaces the Dreamcast's GD-ROM drive with an alternative storage method, typically SD cards or USB storage. These devices typically use an FPGA to simulate the GD-ROM drive hardware.

Examples include:

• GDEMU (official version and clones)
• USB-GDROM
• iceGDROM (DIY, not a product)
• MODE - Multi Optical Drive Emulator Unreleased, preorder here
