I dumped yesterday the game Shin DX Okuman Chouja Game.

I did not know that this game had already been submitted by themabus under a different name: New DX Okumanchojya Game until I tried to rename my dump files with the datfile (name conflict were reported by Clrmame)

I tried to report the Japanese title reading the Furigana spelling while themabus translated shin (new) and spelled differently Chouja.
I made further researches (my Japanese skill with Kanji is not very good) and it appears that the correct tilte (spelling and words) would be: Shin DX Okumanchouja Game
which translates in English in something like: New DX Billionaire Game
Apart from this themabus and myself obtained the same dump, so I think that the following entries should be merged


http://redump.org/disc/1905/


http://redump.org/disc/2599/

Merged.

Every (trusted) site I visited lists it as Shin DX Okuman Chouja Game.

I don't know.
The first Kanji "Oku" means 100 Millions.
The second one pronounced "Man, Ban" means 10000.
Chouja means millionaire.
I have 3 different Japanese dictionaries here at home and the word Okuman doesn't exists on its own. It exists the word Okumanchouja (very uncommon word, it doesn't appear in 2 of my 3 dictionaries) meaning billionaire/multibillionaire.
Hope this helps.

Of course it helps! Good explanation
