That was the first thing I thought of, but I guess you figured it out after I scrolled down. However, Shining Force was on Sega Genesis not PC. I know because I spent forever playing Shining Force II hoping they wouldn't cycle it out of my Sega Channel menu the next month, but ended up staying on it for like a year. SEGA CHANNEL!
You know you can get them on Steam, right? http://store.steampowered.com/search/?snr=1_4_4__12&term=shining+force
