MadriSX & Retro -the expo of retro console/computer stuff of Madrid-

In this expo, guests will be able to get to know any existing projects or novelties related to the MSX and other classic systems. Demonstrations and interesting conferences about retro gaming/coding are held throughout the whole day.
This year, the expo will feature the RetroParty MadriDC team, which is dedicated to Dreamcast, GP32and “vintage” mainly. In the RetroMadriDC area, you will hopefully be able to see some alpha/beta versions working of some of the most recent emulators/apps in the dreamcast and gp32 scene.
