  1. I think it would be cool to port "Mugen" to the Jag some kind of way. The Jag is definetly able handle the graphics; it think it's just a matter of taking a look at how Neo Geo were able to push their system graphically especially around the end of the system life span. If I recall the Neo Geo didn't have as much RAM as the Jag, they basically turned everything into sprites, including the backgrounds, because their sprite hardware could display faster if the background were divided into 8x8 or 16x16 bit blocks. Cinepak works similarly only it uses between 4 to 8 compressable vectors within the aspect ratio criteria of an 8x8 bit block so the Jag is very much well able to handle Street Fighter 3.

     

    The Neo Geo was an all sprite system, the entire games were rendered with sprites, the backgrounds scroll layers ets. Also, the cart version didn't have much RAM (140 kB iirc), but it was a ROM monster, it did pretty much evrything decompressed in ROM. (hence the large and expensive cartridges) The Neo CD had to be a RAM monster to compensate for this, with a total of 7 MB distributed to various areas.

     

    BTW are you also on sega-16? ("philiptwood" same avatar)

     

    Yea... philipj is the name I kept here for sometime since about maybe 2004...? I never changed after all of these year but I decided to let all of my avatars be the same. I tried using "ace" as my user name here and at sega-16 which is the same name I use at another forum but some has already used it.

     

    I guest the point I was trying to make is that the Jag is more then capable of handling Street Fighter 3 and I think most who know the system would certainly agree.

    Thought you guys would get a kick out of this:

    Came up in a thread over at sega-16 http://www.sega-16.com/forum/showthread.ph...7263&page=3

     

    :lol: We need a release date man. This is some great stuff.


  3. I was #157 and did NOT expect to get one, so I was very pleased that I got an email and gladly sent my payment. After buying 3 developer jags with Alpine boards and not ONE of them working properly, I am truly grateful for the work Tursi and Kskunk have done.

     

    I dunno...for some reason I felt compelled to write that.

     

    Good work.

     

    And to think I was actually going to dish out about $300 or $400 for one of those just so I could dev for the Jag. I'm glad I didn't.


  4. Same here. At first I didn't get a reservation e-mail. I was worried, so I asked and recieved the confirmation e-mail.

     

    While I can't speak for Tursi, and I don't know the whole situation, I do know what it means to release a product.

    I do believe Tursi and KSkunk set up the preorder page and the ordering system for a good reason.

    I think it is amazing how many orders they can process in such a short time.

    Keep in mind that they do it all as their HOBBY. Not as a fulltime job and not for a living.

     

    Reading that there are preorder numbers of over 160... Some maybe even with mutiple boards...

    It must be a LOAD of work to manage that in such a short time.

     

    I just recently sent my payment and can't wait to get my hands on the board to finally get some code done again.

    I had to switch to Project Tempest for a while, but it just doesn't replace a real Jag.

    It leaves a lot of work, due to the differences to the real hardware.

    So, can't wait :-D

     

    Keep up the good work, folks.

     

    It's whorth the wait... I just sent my payment in yesterday, but I also have the first Skunkboard he released. It's a solid product so the second boards should be even better then the first.


  5. I'd love something that worked on 7800 and emulated all of the 2600 cartridges as well ( like the Chimera cart ) - I bought a skunkboard for the jag - and something like that would be perfect :)

     

    Absolutely... When the CC2 was released both times, I didn't have the money to get it then, but now I got the money to get and their not making any more of them. :? That's messed up. ;)


  6. Interesting. This is what is on Wikipedia:

     

    I found the PDF from http://nesdev.parodius.com/ this website that's been around for some time now so I assumed they're knowledgable about the NES. The site claims that the PDF was composited by some individual(s) who created NES emulators. I haven't read the PDF all the way through, but I found out what I needed to know concerning the PPU in comparison to the 7800. The Maria moves roughly at about 7+megahertz which is slightly faster then the NES, which means the 7800 could've easily smoked the NES graphic wise under better circumstances if the hardware was designed a little better.

     

    I haven't played the CV much so I don't know a lot about it like I should. I just thought it to be interesting to know

     

    So there is only one 'thinker' in the 7800 where as opposed to a Genny that uses a 68k and a z-80, where

    the 68k is the CPU and the Z-80( which by its own right is a CPU) is but a mere sound support processor

    for genny games. I believe it also uses the z80 for backward compatibility with SMS games when using

    the power base converter? Someone?...At any rate......the z-80 may have also been used for other tasks

    but I cant say for sure.

     

    I think if the Genesis processors were to switch roles from a graphical stand-point, where the Z80 were to do the graphics and the 68K was to be free to be programmed to do other things, the speed of the Motorola leaves a little leverage for some extra processing activities beyond mediocore 2D graphics thus I wish it were possible for the 7800 where the Maria can function like a CPU and the Sally a graphics processor. Considering what the Z80 did for the Sinclair, in which I never really owned but have seen lots of graphic demos on youtube, the payoff would be in focusing the slowest processor to do the graphics and AI while the fastest processor be used to back-up the slow processors graphical capabilities with extra processing activities. Now that's what I call "Blast Processing." :grin:


  7. Nintendo graphics chip the "PPU or Picture Processing Unit" had 16kb of RAM to do all sorts of graphical stuff.

     

    You sure the NES has that much memory? I thought it was more like 2K ram + 2K video ram.

     

    I found this PDF the other day at a website address I can't recall at the moment, but according to what I remember reading is that the PPU use 16KB of memory exclusivly for video RAM divided in half, which implies that more seperate RAM is used for other purposes... 8KB for sprites and the other 8KB for background. If the 7800 had this feature available on the system with having the added to a cartridge, programmers would've had more flexibility becuase the temptation to pinch a penny/save a dollar is always there when it comes to making 7800 cartridges on a budget. Had the extra RAM, and Pokey, been there in the first place, then adding even more RAM to a cartridge would've been a bonus option for the 7800 programmers of that time then there would've been nothing to keep the 7800 from flurishing depending on the game maker.

     

    The 7800's TIA is a peripheral chip, not a processor.

     

    Man that's too bad... The Maria would've made an excellent processor as fast as it is. I see I still have a great deal of reading to do for the 7800.

  8. I think if Atari had gone back to the drawing boards with the 7800, especially with the Maria, the 7800 may have had a fighting chance. Nintendo graphics chip the "PPU or Picture Processing Unit" had 16kb of RAM to do all sorts of graphical stuff... That was the advantage the NES had over the 7800, however the Maria was/is much faster then the Nintendo PPU. Another thing was the difference between the 6502 chips for both systems; the NES CPU was the full 6502 processor in comparison to the 7800 TIA. I just found it pretty facinating to know that the 7800 was that close to being that much more graphically powerful over the NES. Don't mean to go off topic here... Just thought I'd throw it out there. :)


  9. Just think what the 7800 could do then, it wouldn't have to generate any backgrounds and only take care of the sprites and game logic. Think Space Invaders with a scrolling moon backdrop or Xevious with a real looking ground scrolling by or Joust with real looking lava pits...

    Think how exactly those sort of games crashed and burned in the marketplace.

     

    I remember Don Bluth once describing Dragon's Lair as a "Paticapatory Interactive Game" being that Dirk the daring couldn't be controled the way Pac Man could be in a video game. I think that had a little something to do with the market, plus the fact that the video game industry at that time suffered financial losses with the over satuation of Arcade games.

     

    I think Atari should've redesigned the 7800 after the release of the NES before they actual released the 7800. It would've cool to see a lazer disc player for the system.


  10. I wouldn't call it a problem, but when I saw this topic I certainly can relate to enthusiasm... The desire to want to see the 7800 continue beyond its retro status. It's a cool system with a Maria processor that probably didn't see its fullest potential realized in its short life span so I can certainly relate to wanting to see more from the 7800. That's just my personal opinion on the matter, but I do think it would be cool to see a CD ROM drive for the 7800. :)


  11. I personally never owned a Flashback or the Flashback 2, but on of them was suppose to have a couple of 7800 games on it. However the actual Flashback hardware wasn't really like the 7800 if I recall. Now I could be wrong about the Flashback; the point I'm trying to make is that I'd like to see a new 7800 with a CD unit. One with a cartridge slot and perhaps an extra Pokey or Speakjet.


  12. Not to get off topic here, but the Flashback 2 really didn't do the 7800 any justice... In my opinion if your going to make a CD ROM unit for the 7800 it's probably best to do what wasn't done for the Flashback 2 by including a cartridge conector and a CD ROM drive. And while you're at it include a USB port for homebrewing. :)


  13. I'd really like to see another cartridge game built for the Jag. CD are great, but the cartridge really is more universal then the CD unit... Any one who owns a Jag will have a cartridge connector to it. :cool:


  14. I have to agree... And I'm quite sure that the charity would agree as well. He could've just kept the money for himself but he didn't. He may have his ways, but his actions speak louder then words. Critisms come and go, but the measure of a person is defined by his or her deeds and not always a persons personalty. Just the fact that the auction ended the way it did implied to me that the game obviously had value to it if someone was willing to pay that kind of price for it. If anything it should excite people enough to want to make new and better games for the Jag... Doesn't the Atari community deserve it?


  15. Basically yes,

     

    Although I am not to familiar with the original dev.kit this is probably similar in basic functionality.

    Here is my page about the original 7800 dev kit. :)

    Has anyone ever successfully assembled a RAM card...? and if so, what was the results of it? :?:
