Mega-CD official documentation
From Sega Retro
Oldie: biggestsonicfan found these docs... those first five Mega-CD documents are basically identical to the documents hosted on archive.org (the difference is just the watermark they have ... "Sega Ozysoft")... but I think these are better than the ones we already have because, at least, the dates are visible ... so should we upload them as new versions of the files we already have?...--Asagoth (talk) 05:00, 9 May 2019 (EDT)
