RGCD RGCD (Retro Gamer CD) initially started as a retro-gaming CD-based discmag that I first published pretty much single-handedly back in 2006. Growing as a collective (and in popularity), over the next few years we released a further four issues before real-life finally caught up with me and I unfortunately no longer had the time to compile and edit the magazine in 2009/10.Although the magazine side is still very much something I'd like to return to in the future (although perhaps in a different format), since 2009 RGCD has evolved into a games development team and retro publisher, concentrating on the Atari STE, PC and C64 platforms. 34 clicks
