That's what I read on the comments under this youtube video even if the Youtuber didn't quote his source with the thread I created in July 2018 in this "Sega Discussion" topic (https://assemblergames.com/threads/...-project-is-simply-the-mega-cd-isnt-it.69525/), which is quite disturbing because that's what I do and it doesn't seem fair to me. Whatever... My question : is it believable ? What do you think ? Original source (February 2016) : http://segareniassance.blogspot.com/2016/02/the-misunderstood-mega-cdsega-cd.html Sega United (December 2018): You are ABSOLUTELY positively correct. “Sega Earth” is indeed the Codename of Mega CD. And Yes, it DID start off as a Laser Disc Add on Project for Mega Drive between SEGA and Pioneer in 1988. Due to Costs,limited silicon and risky bulk BOM pricing, it was scrapped in 1990 for CD, and SEGA ultimately went with JVC. Sega United : Also there was no “Project Saturn”, SATURN’s original Codename was “AURORA” in 1993. And not correct regarding “Project Jupiter”. JUPITER was a totally different Chipset from Saturn. It was going to use Model 1 3D technology, instead of Model 2. Saturn uses low end Model 2. Jupiter ultimately became the Sony PSX. Dusk Racoon : Makes somewhat sense. I mean, Sony was working with Sega on the new hardware. Just sucks Sega of Japan wasn’t for it. Sega United : Actually they weren’t. Sony had actually been planning a Console of their own since 1990 while signed on as a 2nd Party Partner for Nintendo’s Super Famicom, instead of doing R&D and taking the time to create their own product, Sony decided to talk its way out of the contract by creating a New Clause that would literally give them 80% Control of the Super Famicom CD add on, 30% Control of Super NES silicon, 100% OEM rights, plus the Rights to use Nintendo’s IPs like Mario and Zelda. Sony basically created a Loathsome contract that they knew Nintendo would HATE, in the middle of that, Sony found a Loophole and ended up using the Super Famicom CD add on patents and designs and stealing the “Nintendo PlayStation” IP. Regarding your claim, Sony never worked with Sega on Jupiter. They tried to eavesdrop on SEGA of Japan in September 1991 regarding upcoming Next Gen Hardware projects, but were thrown out of their Offices for making boisterous claims that couldn’t be substantiated. Sony then approached Sega of America, LIED to them about having the rights to manufacturer Sega CD when JVC has EXCLUSIVE OEM rights to Mega CD/EARTH (since Sony and Philips patented and owned CD ROM technology), and claimed to SOA, that they could design and make a CD based 3D only chipset for JUPITER, and promised SOA to meet with them and head to Japan to pitch the chipset to SEGA by March 1993. Sony NEVER met with SOA, Refused to return their calls, deliberately ignored their messages and faxes, and in the Spring of 1993, Reneged on their Promise to meet with Sega of America to discuss the pitch prospect. Instead, Sony RAN off with the Chipset and LOCKED it down. PSX is STOLEN Jupiter Hardware. Pure and Simple. It was originally and solely designed by Sony to Destroy and Dominate Sega Jupiter. Sony didn’t see the Saturn coming, neither did Sega of America. Aurora was a SURPRISE, and top Secret 64-bit project at Sega Away and SEGA AM3 and AM4 that begin in Early 1993. Dusk Racoon : So basically the PlayStation as we know it now was originally Sega’s hardware, but Sony stole it? Is that why the 32x and the Saturn were released and flopped? I do know the Saturn was hard to program on which lead developers to jump ship to Sony. That and the fact that there really wasn’t many retailers selling the Saturn. Sega United : Yup. PS1 is STOLEN SEGA Jupiter hardware. Using Stolen designs of Nintendo’s Super Nintendo CD add on. 32X was an extremely misguided,half baked idea from Sega of America and solution regarding the System 32 based MARS" Chipset. SEGA in 1990-1991 had been working on a Full fledged successor to Mega Drive called “Giga Drive” or Sega Mars. They scrapped it in 1992 after being WOWED by Nintendo’s Star Fox and turned to Jupiter and Model 1 3D instead. In Early 1993, SOJ sent GD prototypes and MARS prototype over to Sega of America with instructions to “Combine Genesis and Sega CD into SKU using System 32 Chips and make a 32-bit CD upgrade of Sega CD” codenamed “Sega CD X”. Sega of America was afraid that Genesis was going have a Huge dropoff in 1994, so they kept trying to suggest ways to keep it fresh and keep it going, at First SEGA of Japan suggesting copying Nintendo’s “Super FX” method with SVP" but SOA didn’t want to do it, SOA then assured SOJ that they had a plan, what SOA didn’t tell SOJ is that they were simply going to upgrade Genesis using System 32 tech, by exploiting Genesis’ hidden 32-bit Register Bus. In Early 1994, SEGA of Japan initially gave “Genesis 32” or “Genesis 32X” a thumbs down and “NO”, but Parent Company CSK and its owner Isao Okawa went behind Hayao Nakayama’s back and greenlit the 32X for Sega of America. Saturn didn’t flop, it underperformed its first year and half due to its steep price and minimal 3rd party support. Sega of America had completely dropped the Ball on Saturn, Wasting ALL of 1994 on 32X and missing Saturn’s first year. By the time SOA had moved on to Saturn, nobody there had any idea how to properly program and code games for it. They were confused as hell by its design and failed to teach Western 3rd Party developers how to properly make games for it and properly use the SH-2 Aurora Double Sided(Dual Core) 32-bit CPU. fightclubhubs : @Sega United : The PS1 hardware was not stolen plans because Sony was the ones who approached Sega after Nintendo dropped them in favor of Phillips. Sony designed the Playstation add-on for the snes and modified the hardware and presented it to Sega. SOA was interested but SOJ was against the idea and decided to use their own in house hardware. You can read the interviews from SOA president Tom Kalinske, who was for the joint project. Sega United : @fightclubhubs Yes. It WAS Stolen. Sony was signed on as a 2nd Party OEM for Nintendo regarding Super Famicom, they signed on in Late 1988 and co developed and designed the SA-1 Co Processor as well as designed and manufactured the Super Famicom’s Sound Chip. No, Nintendo didn’t drop them in favor of Philips, they DROPPED the Contract in 1991 after it was revealed that Sony’s Clause would have given Sony nearly ALL control of the Super Famicom CD add on the Playstation as well as access to Nintendo’s IPs and 100% OEM rights on Super Famicom. Nintendo approached Philips because they figured that Philips would provide them a CD ROM license, which makes since since Sony and Philips co developed CD-ROM and CDX technology. And unfortunately, that’s not correct. We’ve spoken to people close to Kalinske and AG themselves personally met and spoke to Tom Kalinske last year, Sony never Showed SEGA ANYTHING. They went to SOJ FIRST, NOT SOA. They met with SEGA of Japan in September 1991, and then to Sega of America in the Spring of 1992. Sony didn’t modify the Hardware, they didn’t even USE any designs from the add on because they legally could not. They instead USED blueprints,Trade secrets and Documentation of Sega Jupiter provided to them by Sega of America. Sony is NOT innocent and it is a lie that they were interested in working with SEGA, they were Not. They had plans for their OWN Game System, being CD ROM based dating back to 1990 and exploited being an OEM to get it made. They stole Nintendo’s IP and Casing Mockups for Super Famicom CD to design PSX, and then STOLE Sega of America’s OWN designed Chipset for Jupiter by lying about being licensed to manufacturer Sega CD SKUs. fightclubhubs : @SegaUnited : In an interview with USgamer, Kalinske stats that Sony’s Olafsson and Schulhof came to him and SOA where he agreed on the endevour to team up on a new console. ““We had the Sony guys and our engineers in the United States come up with specs for what this next optical-based hardware system would be. And with these specs, Olafsson, Schulhof and I went to Japan, and we met with Sony’s Ken Kutaragi. He said it was a great idea, and as we all lose money on hardware, let’s jointly market a single system – the Sega/Sony hardware system – and whatever loss we make, we split that loss.”” After that, Tom went to Nakayama who said no, calling it stupid and that Sony had no idea how to make a game console. There were no stolen plans, Everything was a joint venture until the Board of Directors from SOJ ended it. Sega United : @FightClubHuBBs : Tom Never went to Nakayama regarding Sony and Jupiter, SOA and SOJ RARELY shared information with each other regarding OEM prospects and actual internal R&D, especially with the Large Culture Barriers at the time. SOJ did not find out about this planned pitch prospect until Early 1993, they had already REJECTED doing ANY business with Sony long before that. Kalinske was referring to what “Sony told us in 1992 regarding their idea for a CD based Jupiter Chipset”. His accounts are from 1992. Again, Sony FIRST met with SEGA of Japan in September 1991 BEFORE they came to Sega of America in '92. Kalinske confirmed this with AG last year. SOA thought that Sony wanted to provide a CD ROM based Jupiter design and was scheduled to meet with SOA in the Early Spring of '93, Sony NEVER fulfilled their end of the bargain, they instead threw together a design based ENTIRELY on PC components using Jupiter Documentation,designs and proposed Specs, and again NEVER returned SOA’s Calls and Fax Messages. Before SOA could even meet with Sony, they finally discovered that SEGA of Japan had already previously met with Sony, had rejected any plans for partnerships with them, and also that Sony was ILLEGALLY manufacturing Sega CD units. JVC then filed a “OEM Infringement” Lawsuit against Sony, as a result, Model 1 Sega CDs were abruptly pulled from the Market. Sony NEVER,EVER fulfilled their obligations to Sega of America, they pretended that they had interest as a 2nd Party Partner for Jupiter, promised them a CD ROM Chipset build, but instead of allowing them to use it, RAN off with it and locked it down. There’s a Reason why Aurora/SATURN was kept Top Secret and why SOA was left in the dark about it: When SEGA of Japan found out about Sega of America meeting with Sony for the Jupiter and had shared Top Secret Information on JUPITER to Sony, SEGA was Stymied and had to Retool the ENTIRE Jupiter Project. I don’t think you understand how much this affected SEGA’s R&D, the Saturn design ended up being thrown together hastily in Mid '93, because Sega Away ultimately had to scrap Jupiter altogether after Model 1 had a very POOR showing and debut at JAMMA/JAEPO in the Summer of 1993. Hideki Sato,Hideki Okamura and Yu Suzuki had all started work on a planned Full fledged Model 2 based Console codenamed “Aurora” in February 1993, AM3 was working on AURORA, while Sega Away 27 and AM4 were working on what was called “Project Jupiter Phase 2” Which basically was going to be “System 32 with Model 2 3D technology”. The Reason why JUPITER got scrapped is because Sony basically lifted and STOLE all of its designs,specs,documentation and blueprints. If they were so innocent and what you claim is true, then they wouldn’t have had a Prototype already by the End of 1993. Before Scrapping Jupiter, SEGA decided on a compromise: Instead of Abandoning Jupiter P2 and instead of moving forward with the Ambitiously costly 64-bit Aurora Project, Nakayama decided that it was just be practical to combine both Projects together into One and thus it was christened “SATURN” from Jupiter to Saturn, The Next Logical Step. Saturn is ACTUALLY a 64-bit Console at heart. Pseudo 64 bit to be exact. Okawa forced its Beta Design to be rushed into production and cut off the proper 4 month taping it needed in order to be properly documented and designed. FYI, Saturn was also Cartridge Based much like Jupiter, CD ROM RISC or CDR was added as an Afterthought to the Design. Saturn itself was released as an 80% Compete product. Its actual core design was incomplete. fightclubhubbs : Can I see your sources please? There is no info I can find about Project Jupiter being shut down because of allegedly plans being stolen but because it wasn’t cost effective to have a cartridge/cd hybrid 32bit system. And that the plan was scrapped in mid 1994. I also can’t find any info about this lawsuit from jvc against Sony, or evidence of illegal sega cd manufacturing.
