| First off, I'd like to say that I have no experience with ROM hacking, programming (except for PHP, HTML etc.), and I do not own a Satellaview. I've just been thinking a bit.
When St. GIGA stopped broadcasting for the Satellaview, the unit got pretty useless. Now what I've been thinking about is, if it would be possible to somehow make an interface between the Internet and the Satellaview. I mean, originally (from what I know), it got its data from a satellite reciever that was connected to St. GIGA. If we could somehow find out what data it sends and which responses it looks for, would it be possible to "emulate" the satellite by connecting to a server through the Internet? Accomplishing this opens up tons of new possabilities like broadcasting ROM hacks and ROM hacking news. Maybe it would even be possible to make the games send and recieve data over the internet. So, what do you think? How hard would this be to do? |

| That would be quite a specialized project and I don't see the point really. You're basically saying you want an emulator that can download roms itself. Or something to do netplay with, which is already in emulators. | |||

| Nonono... Just somehow provide the same features as St. GIGA. Like audio streaming, getting updates, news, downloading new games and such. And yes, of course we have the computer. But it would still be something else to have this running on a SNES. | |||

| Ehn, Yoronosuku has one of those Satellaview units lying around somewhere. I remember we played with it a little bit but as far as I know nothing useful ever came from it. Go on and ask her though, she might have done something with it since then. (edited by Keitaro on 05-06-06 12:16 PM) |

....wow, what the hell kind of typo. Um, I meant nothing useful came from IT. Not you  yeah. Sorry about that. |

No problem.  It just made me lift an eyebrow. |

Well...I have the unit, and I'm trying to find how to interact with it. . .if I can get function, I would love to see if the American model SNES is capable of running it. Does anyone have any technical specifications or documentation on the unit that I could look over? It would be a very big help  |

| Wikipedia has a small description of how it works, but it's not much. What about checking out the ROM?

| That sounds like it is just information on any given peice of software transmitted over the unit, not much help to someone trying to work the unit themself unless they were sending software to it (which I cannot). I think reviving it is sort of impractical, anyway. . . not many people outside of Japan (and at this point not many people IN Japan) are going to have the unit, and you would be better off emulating a similar function rather than designing something very difficult that is never going to see its full useages potential.
My only reason for fooling with the BSX was the prospect of loading custom software on a host unit. I've sort of given up hope/interest on it but at this point that sounds like the only practical use for it.. |

Originally posted by Boom.dk your idea sounds nice, but im afraid it has little practical value. Originally posted by Boom.dk what would be the advantage of downloading hacks and news to the satellaview as opposed to a computer, the internet and a backup unit? exactly, there is none! actually, the satellaview method would be absolutely inferior. first, the so-called satellaview modem isnt a real modem. the term modem is derived from modulator-demodulator, implying the ability to send and receive data. the satellaview however can only receive, not send data. this is a limitation imposed upon the system by the satellite uplink technology, obviously. the satellaview has an expansion slot most likely meant to host a phone line modem, but to my knowledge, it wasnt released and i've yet to see any satellaview games that'd take advantage of it. that means the user would have no means to control what content he'd be downloading and he must switch the unit on at the right time to be able to download anything at all. second, the capacity of the flash carts is 8mbits. add in the 4mbit psram and you have an absolute maximum of 12mbits. that cancels out most newer games and most expanded rom hacks. also, many hacks were never tested on a real snes and wont run on anything but emulators. third, consider the userbase. yoronosuku has one. i have one. maybe there are 2 or 3 other people around here that own a satellaview aswell. youre probably looking at a userbase of less than 10 people worldwide. i bought mine minty in box for $30 on JY a few years ago, but even in japan, youre paying at least $100 for a complete system nowadays, so its not like everybody who wanted one could get their hands on it easily. Originally posted by Boom.dk even if you'd be able to send data to the satellaview, where would you pull data like the audio stream or the missing dungeon data for the zelda kodai no sekiban series from? right, its lost forever unless someone breaks into the nintendo of japan HQ. the games that dont run because of incorrect emulation of the bs-x bios cart would be playable on real hardware, of course, but you dont need the satellite uplink for that. you dont even need the base unit. just the game on a flashcart and the bsx bios cart. i've been researching the satellaview quite a bit in the last month and was able to reverse-engineer the various protections related to booting programs from the flashcart and parts of the base modem registers and inner workings, although im not completely done yet with the latter. just for the record, some of the flashcart/checksum info and almost all of the base unit information available on the net is flawed.

Originally posted by Boom.dk didnt mean to. in fact, i had very similar ideas when i started out with the satellaview. i pointed these things out because thats just the way it is. i'd find it quite amusing if somebody was able to establish a communication to the modem through the bs-digital input, in a proof-of-concept way. i just dont think that you could do anything useful with it nowadays. havent looked up how that bs-digital stuff works, either. there should be plenty of information available, though, the format exists since 1984 or so and appearantly, many japanese satellite receivers have that digital data output. from what i've heard, there are several channels multiplexed into one bitstream, but i might be wrong. after having a look at the components that handle that data line in the modem, i'm guessing that its actually no simple binary bitstream. i'm not educated on that, though. at any rate, it wont be as easy as just connecting it to some pc port and throwing random data at it. |

| Okok, so maybe it's not as useful and I may have thought. I still think it would be interesting, though.
