Speaking of Hudson's development unit in Hong Kong, they actually sponsored a (really obscure) TV drama series (sorry, Chinese Wikipedia page only) here in the early 90's, which was about a certain game designer who created Bomberman(yeah... and I am not making this up; the script writers were) and a girl supposed to be a game character (in Cotton even, according to the Wikipedia page, but I couldn't remember this) he designed somehow came to life in reality. The story was just clinched and silly like this and it was not very good IMO.
However, there were loads of references to Hudson PCE games (mostly visually as props such as game flyers and game screens on monitors; the descriptions were all made up) and it used a lot of game musics as BGMs (most frequently and blatantly the AWESOME CDDA tracks from Far East of Eden II).
I bet there might be some scenes that some of the PCE development tools were shown on screen too.
AFAIK that division worked on the PCE version of Ninja Ryuukenden, which was quite obvious as it contained a secret language switch code to switch the game between Japanese, English(even though this version was never released in the west I think) and Chinese. This may account for why this version was considered lacking in some aspects(ESPECIALLY the parallax scrolling part), which was probably due to the people there not being experienced enough at the time.
This is confirmed from
GDRI and apparently they developed Cotton too. That explains why Cotton appeared in that TV drama. Considering the (extremely) frequently appearance of Bomberman in the show it is quite possible that they are responsible for (co?)developing some of the Bomberman games too.
And yeah. It's nice to hear someone who used to work there BITD still has the tools.
