Gah, the madness of it all, haha. I'm majorly anal about the organization of Turbo/PC Engine games. I can't stand having the colors all mixed up. No matter what the system, I sort US and Japanese releases separately, but I have to take it a step further for my NEC stuff. I only have orange-spined TG-16 releases so far so that's easy enough, but for the Japanese releases, HuCards, CD-ROM, Super CD, and Arcade are all separate and then alphabetized within those groups (alphabetized according to the Roman alphabet, going off however the title should be properly romanized). Big box and normal jewel case PC-FX games also are kept separate, obviously.
