I could use your help at this point, this site has a lot of obscure mech data has been missing for quite some time, it would be great if you decipher the text better than I can. Google Translate can only help, but so much.
I look at Garma's Gelgoog. It mentioned the unit was featured in Wonder Swan Color's "Mobile Suit Gundam Gihren's Greed Special: The Conqueror of Blue Planet" (2003) , but it also cross-referenced mahq.net's Gihren's Greed mecha page:
which is the original Saga Saturn's Gihren's Greed released in 1998, and it did not feature Garma's Gelgoog back then. So, without actually played "Gihren's Greed: Blue Conqueror" or actually actual pictures from game guide or screen shot, I am quite sceptical whether such information should be featured in Gundam Wiki, without any connection to official sources.
