After I shipped the DOOM Black Book , I took some vacation in Japan where I was able to play Ikaruga on a real arcade at Taito HEY in Akihabara. The experience reignited my interest in SEGA's ultimate video game console, the Dreamcast. There is a lot of documentation available online which made the studying process…
