Is it possible this company is connected to (or the same as) GDRI-007? For one, some of the names in the credits line up: an artist named "Ikeda" and someone named "H. Yamada", "H.M. Hammer" -> "Hamagaki"? For two, I scanned for shared data between FC Peepar Time and Putt Putt Golf, and while not much came up what was there also popped up in Go Go Bowling and Chuka Taisen (along with a few other Jaleco and Taito titles).

I wonder if Funky George, or maybe Soul Duke, is JuNya Kobori. His profile says he worked on the Mega Drive. CRV (talk) 17:45, 2 March 2017 (CET)

Disassembling random games to take a peek is fun... I was recently reminded of a similarity I found in a number of games that used a similar system for their main loop routines, involving arrays of data including a function pointer that get loaded in a special way in RAM and then run. I did a binary search for a portion of the common code and came up with this:

Jantei Monogatari (Japan).md: 00008930
Metal Fangs (Japan).md: 00000378
Ninja Burai Densetsu (Japan).md: 000029be
Rent a Hero (Japan).md: 0000121c
Sword of Vermilion (USA, Europe).md: 000010ac
Vermilion (Japan).md: 00001018
Wrestle War (Japan) (Beta).md: 00000842
Wrestle War (Japan, Europe).md: 00000846

I don't know if you noticed this already in a code comparison but eh. Metal Fangs's credits are initials only and are plaintext in the ROM and I am looking for Jantei Monogatari's. I'm not sure if this says anything about GDRI-010; I'm putting it here because of Wrestle War's confirmation - Andlabs 10:51, 30 March 2012 (CDT)

Well it doesn't have credits (apparently) :/ (set FFFFD0:0053 at startup to replace the intro cutscene with the ending cutscene) - Andlabs 11:00, 14 April 2012 (CDT)

Dynamite Dux (arcade) does the same thing! That game does credit a programmer "duke" as Assistant Programmer... is it our Soul Duke? (If you deinterleaved the ddux1 ROMs, which aren't encrypted, the code I looked for above starts at $4D2). The data structures and values aren't exactly the same, of course. While the screen mode function is the same, after that I can't see many code similarities... so I don't know if the programmer's style evoled or I'm not looking hard enough or this guy didn't work with the same people every time - Andlabs 00:35, 17 May 2012 (CDT)

As old as these comments are, I'll just note here: the "duke" credited on AC Dynamite Dux is Tomoharu Kimura, who worked at Sega until he left to help start Genki in 1990. He also worked on Vermilion and (possibly) Metal Fangs before he left Sega. Rent A Hero and Ninja Burai Densetsu were largely by the same team after some people left (and all these games have sound by HIRO). No idea about Jantei Monogatari, but if Wrestle War is based on the arcade version's code, that may be why it appears there too as the high score list suggests internal Sega development.
I suspect that "Soul Duke" is probably not the same person.--Dimitri (talk) 01:33, 16 January 2017 (CET)
