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.
A DreamShell image with 32MB patched BIOS images is available. This image contains a variety of nearly 50 BIOS images including the stock BIOS, japanese-cake BIOS, DreamBoot BIOS, and DreamShell BIOS, in a variety of flavors for each.
- *WARNING* THE IMAGES ON THIS DISC ARE EXPERIMENTAL. THE ONLY TESTED 32MB BIOS IS THE jc-v1.032-32MB.bin IMAGE.
- IF YOU FLASH YOUR DC BIOS WITH A 32MB BIOS IMAGE FROM THIS DISC, MAKE SURE YOU HAVE A FUNCTIONING BACKUP BIOS TO RECOVER YOUR DREAMCAST.
- Seriously! We are not responsible for damage to Dreamcast units due to the use of this disc. Read the warning and know what you are doing.
