  1. I'll probably regret this, but I'm in a good mood. So let's assume than the original poster is serious and rational, unlike the many people who have floated similar ideas before. To sum it up, as someone with more than ten years experience in developing that sort of stuff (both in hobby and professional contexts): - don't trust magazine articles ; lots of them are somewhere between "partly wrong" to "complete fantasy". Even with the bugs fixed, the Jaguar would be significantly less powerful than the PSX. - removing the 68k means that your Jaguar 1.5 would be incompatible with 100% of the existing games. - as CyranoJ mentioned, the community is small already. We don't need more fragmentation. - games with the level of quality you're expecting require professional development teams, with matching salaries. - and the elephant in the room: like others before you, you're not realizing how huge and complex the technical part of this project would be. Compared to this, the business part is easy. If you still want to go ahead, I only have one piece of advice: Forget about the business for now. Find someone: - with experience in developing similar projects (ask for proof of actual custom-designed hardware and firmware of similar complexity) - with experience in low-level retrogaming technology in general, and the Jaguar in particular (again, ask for proof. Putting an emulator on a Raspberry Pi doesn't qualify) - who's interested in the project - whose prices are compatible with your expected budget If (not when -- if) you find someone matching all of these criteria... then you can start thinking about market research, fund raising, etc. Not the other way around. Otherwise, your project is doomed from the start, like its predecessors.
  2. Just FYI, there has been no formal scientific proof that every post in this thread is entirely factual and/or serious.
  3. That's just a fancy way to say "I have 3 small, empty cardboard boxes".
  4. It doesn't even include such classics as Checkered Flag or Supercross 3D. What a rip-off.
  5. Let's say that there are already ways to detect emulators without the need for patches, and CJ is aware of them
  6. You know, the first step to healing is acceptance... We promise we're not going to judge you.
  7. And if you still have troubles with the controls, don't worry. I'm sure CyranoJ will soon release a steering patch, just like he did for Checkered Flag. *ducks*
  8. So it means they used both 6P6C and 6P4C connectors on the JagLink II, depending on the production run. If it's by design, that's strange ; maybe they just used whatever was in stock at the time? Since there are two RJ11 ports, you connect either of them to the previous console in the chain, and the other one to the next console.
  9. I don't know if it will be useful to anyone else (I think that most of the Lynx developers in 2021 use a flash cart...), but I've ported @42bs's BLL uploader to Windows: 📎 send_obj Win32 version
  10. Since someone asked, here's my reverse-engineering of the JagLink II:
  11. The first sentence of the JagCD blurb in the first picture is funny in hindsight. It means "As it is manufactured by Philips USA, Atari is confident in the quality of its product!".
  12. Exactly. When you look at how badly Atari was managed, how little money they had, and how short-staffed they were compared to companies like Sega and Sony, it's already a miracle that the Jaguar actually got released and managed to survive for a few years. Including even a "dumb" CD-ROM drive requires additional and significant manpower, time and money ; luxuries than the 1993 Atari couldn't afford. Since both the Lynx and their computer business were winding down by then, and they were competing against many other console manufacturers, they had to release something.
  13. Interesting. Apparently it uses the RotSprite algorithm. Do you have some examples of pixel art that's been scaled down with this? I only found a single image ; it doesn't look bad, but it's hard to judge an algorithm on a single case:
  14. By the way: So it is important to offer a way to disable the Jaglink part, otherwise GameDrive users won't be able to use your product. Putting an on/off switch in series with signal UART_RXD (pin 3B on the DSP connector) should be enough.
  15. Doom uses 9600 bps. I'm not aware of the baudrates used by Battlesphere and Aircars (I don't own those games), but I'd be very surprised if they even approached 100 kbps. I don't remember any other JagLink compatible games. So this smaller and much cheaper part should work just as well as the original: https://www.digikey.com/en/products/detail/stmicroelectronics/ST202ECDR/686406 If you want to be extra sure, compare the detailed specs for both. EDIT: changed part number. The new one is cheaper in small quantities. EDIT 2: yet another change (ST232 -> ST202). Uses the same capacitor values as the original.
