A simple hardware modification for NAOMI and NAOMI 2 to disconnect the JVS controller from port 0 (port A on the Dreamcast). You just need solder jumper JP3 and switch it. This is a very useful for DreamShell and running Dreamcast games by it. After this, you can connect all Dreamcast peripherals to port A. This will result in all four ports available on the side board: A, B, C and D. You need to…

Внимание: наличие оригинального биоса…
