thank you very much for waiting. i'll be having a celebration stream this evening with ohmi on my twitch @ https://www.twitch.tv/msx2plus - probably starting around 6 or 7PM. we won't be playing eos or anything like that, just having fun :)
thank you for your patience, thank you for your support, it's hard to believe this is finally done.
