using Sega Naomi without I/O board

[OldFoo]

hi all, I have naomi & virtua tennis, I dont have any I/O board, so game does not work, my question is, can I use my dreamcast controllers via connecting to maple bus



and is there any project (free firmware & schematics) that emulates naomi's I/O board



best regards

Sorry, no. Only a few Capcom games accept Maple inputs as a secondary control input. Even these games require an I/O to be present.
