Bleemcast! is an independently developed commercial emulator by Bleem! that allows one to load and play PlayStation discs on the Sega Dreamcast. It is compatible with most Dreamcast controllers and steering wheels, and leverages the Dreamcast's superior processing power for enhanced graphics. It was created by using the MIL-CD security hole found in the Dreamcast BIOS.
Indeed, never seen it do that trick before, very cool
This is so sad to read... It makes me so angry that even when they won several lawsuits, Sony could just drive them out of business by suing them some more, and threatening stores that wanted to sell their software.
