Andlabs/Uh er huh hmmm

So when did Sega start in house development of video games?

I don't know the situation with Sega/Gremlin. I don't know if anything on "Sega Blockade Hardware" had anything to do with Sega at all.

The VIC Dual — where did the VIC come from? PCB shots? Promotion only called it DUAL. VIC Tokai? They started around the time the earliest VIC Dual games came out, and those were all Gremlin too. VIC Tokai's games with Seibu lease were done dba Graphic Techno EW

VIC Tokai and Seibu Lease worked together since the days of the Famicom. I think it was Aigiina no Yogen [FC] where the VIC Tokai name was first used. Before that, Graphic Techno EW was used. I believe that Sega's Calorie-kun [vs. Moguranian, AC] was released with the Graphic Techno EW name.

Aigiina no Yogen was apparently 1986

Could we use the SG-1000 games to find out when were Sega starting in house video game development? I doubt. The first three titles on the SG-1000 were N-Sub, Safari Hunt, and Borderline — and we know they were all outsourced to Compile... or one of the various companies that merged into them

• Think Soft (Bee & Flower)
• Programmers-3 (E.I.)
• Nisso (Hustle Chumy MSX)

Or one not listed here. Or they could have been Compile but after the merger and we don't know because we don't have date information (except year), though on older Compile Game History pages (before they split the pages by console) Bee & Flower was listed earliest (last), followed by the three SG-1000 games.

Zaxxon was outsourced to Ikegami Tsushiniki, most known for doing Donkey Kong for Nintendo. It has their graphic symbol in VRAM and I highly doubt it's just a coincidence... of course we (I) could do code comparisons =P
