By replacing the Dreamcast's two 8MB SDRAM chips with two 16MB SDRAM chips, modifying the pin arrangement, and modifying the BIOS, it is possible to install 32MB of RAM in the Dreamcast. Existing games and applications will not be able to address the RAM, but applications built with a patched version of KallistiOS are able to address all 32MB.
