This is a proof-of-concept port/de-make of Sonic CD developed by Simon Thomley in late 2009 and early 2010, based on the Game Boy Advance port.

The project was created while in collaboration with Christian Whitehead, to assist with reverse-engineering and documentation for the creation of Whitehead's Sonic CD remake, prior to its formal acceptance by Sega.

Installation

Hardware

Copy the main "SonicCD" folder (which contains "Player", "R1", etc.. subfolders) to the root of the SD card.

Place SonicCDDS.nds anywhere on the card. Run SonicCDDS.nds.

Emulation

(Recommended) From No$GBA, run SonicCDDSFull.NDS.

(Not recommended) Using DeSmuME:

• In the "Emulation" menu, select "GBA Slot" > "MPCF Flash Card Device", and then click "Use path of the loaded ROM".
