Alright, I'll chime in.
The Typenow is a custom keyboard created by Kant from KBDMania forums which is affiliated or owned by IOmania as well. So the IOmania TypeNow keyboard is their first in house custom keyboard. You could say that the Ddokyu keyboard is the root of all these custom keyboards which was the top dog of custom keyboards (still highly sought after and rare I might add.)
The Cheats is a custom keyboard created by users on OTD forums as you may all know. It was a custom kit group buy deal.
Both keyboards are created separately and are not related to each other in any way as far as I know. I will say this though, there was a break out awhile ago between KBDmania and OTD regarding group buys and such and resulted in a whole mess.
I might offer my help for translating all the stuff properly once I get in contact with Kant, but I won't have time until end of next week. It pains me to see a horrible translation influencing the image of such a high quality keyboard.
