In the late 90s and early 2000 era, Nintendo was all about establishing joint partnerships in Japan. Even though it's not well documented in Western press/archives, Nintendo and Hudson formed Monegi Inc. (51% Nintendo, 49% Hudson) and they were exclusively involved in Mario Party development and a few Super Robot Taisen games. A lot of the veteran ND Cube staff may be directly from Monegi rather than Hudson, although it's hard to pinpoint exactly. Hiroshi Ikeda who was the original Nintendo R&D4 manager during the first years of (EAD) Miyamoto/Tezuka developing games on their own, was the President of Monegi, and then later Mario Co., Ltd which was another spinoff join venture company.
Monegi Inc, Mario Co., Ltd., Randnet Co., Ltd., Marigul Inc., Mobile 21 Co., Ltd are a few of those joint companies from Japan.
Anything is possible but SRD was a wildly different scenario than some of the contemporary contract support studios. Everything from their almost 40 year history being a tech tool developer and program consignment team directly affixed in Nintendo's Kyoto development studio, to their equally important role of being the programming end of the original Super Mario Bros., The Legend of Zelda IPs.
Obviously HAL and IS would be the closest situations to SRD, with the former TEC Co., Ltd (Nintendo/IS co venture) and the original minority stake Nintendo purchased from HAL, but then selling it back and instead settling on the Warpstar joint venture around their Kirby IP - being some earlier moves to sort of establish formal ties outside of longstanding contractual agreements and IP co-ownership. The big difference is that SRD never became its own developer/co-developer but always remained a purely programming arm for Nintendo's design and technology groups.
