I just want to dev for the XM... How do I do that without a CC2 cart?

Its OK for legacy games. For implementing interesting tricks/quirks its a pain, so that sort of development I do on my CC2 and real hardware. It has no debugger so it's hard going in that respect too. What kind of hardware do you use to program the 7800?

Not too late. There's still 69 left! Make that 68 left... Can't wait to get mine.

It's not too late to order is it...? I now have the money to do so.

First off the Jag was released before the PS1 so Sony had a couple of years to get an advantage over the Jag. Secondly the PS1 doesn't sport a 64bit blitter processor; the only reason the Jag wasn't as successful as the PS1 is because the Jag was rushed out the door. Thirdly, the Jag CPU M68k hindered developers from taking advantage of the hardware most notebly the GPU and blitter because of the buggy nature of the system that hogged the bottleneck bus; for that reason, the Jag wasn't able to take full advantage of the GPU speed plus the GPU, until recently, wasn't able to gain access to main RAM. The tools Atari provided for the programmers were crap to say the least plus Atari didn't have the third party support the way other system did.

Here are some links for downloading the official development kit for the Playstation 1. You'll need to download from all of the links to get the full package. http://www.megaupload.com/?d=OUC77RVK http://www.megaupload.com/?d=ICDA8HBJ http://www.megaupload.com/?d=3GLWEU98 http://www.megaupload.com/?d=YFM3TJ2C/?d=YFM3TJ2C Here's the website I got the links from. http://www.snesorama.us/board/showthread.php?t=18779

hmmm.. too much weeks being the "next week", should be this one or at most the start of the next.. the problem is that I'm having fun adding things these are the previous links: http://www.atariage.com/forums/topic/148697-project-m-stage-1/ http://www.atariage.com/forums/topic/152979-pm-1-5/ Thanks a bunch.

Can you give me a link to the thread?

I know this is an old topic, but here's a nice youtube demo of some 3D this guy made using interrupts instead of raycasting.

Is there any particular way to program the XM? Do you need a special cartridge or anything like that to program it? I want to learn how to program this thing.

It's not too late to place an order is it? I might just have the money this week... Do you except paypal?

It was my impression that the GPU was meant to have been the CPU while the Motorola was only put there to have contact with the outside world, while at the same time attract more people to program Jag. My Jag has the same font and it looks like CPU when I first saw it... Then I looked again and the C looks more like the G... It's a little hard to tell.

YES YES YES... OPTION 2.

Are there any only tutorials on modding a 7800? I'd like to mod mine one day.

Version 2 sounds like a winner... Please let me know something so I can set asid the money to get it when it's released.

I hope you all are still considering the 2151 YM... That's still a cool little soundchip.

Any place name "Cologne" can't be all bad... SNIFF...! Aahhh... The sweet smell of success. I'm just funnin. LOL

I couple of weeks ago I was looking "Tiny BASIC," which seems to be more or less generic for porting to other systems. It seems to be a good starting point; it's small, uses 3K of memory according to wikipedia so you know it's going run supper fast on the Jag-RISC. Tiny BASIC Wikipedia

I've always wanted to use the Speakjets for more than just speach synthesis. Theoretically it can handle music as well, if not better, then the POKEY having a couple of more sound channels then the POKEY... I've yet to hear anyone make any music with it though. Will the 2151 be an additional sound chip to be added to the module? Now that would certainly bring the 7800 to an oldschool arcade machine like status provided you all use a Z80 as a sound controller. lol

the unit on display was not functional. I have a couple photos of it on my site, the 2nd and 3rd photo on page 5. That's pretty neat looking... I look foward to this thing being released... It's about time the 7800 got some props. Now all that's left to do is to make some nes style control pads for the system. I would suggest using a speakjet for a sound processor but those things run $24 a pop.

Curt is aiming for less than $100. However, you'll need to factor in the price of games too. How will a USB connector help homebrewers? It'll help by making provision of loading homebrew games on it. I'm not aware of such a document. The best place to start with the 7800 is the MARIA documents :- http://www.atarimuseum.com/ahs_archives/archives/pdf/videogames/7800/gcc1702b_maria_specs.pdf http://www.atarimuseum.com/ahs_archives/archives/pdf/videogames/7800/maria-2_handy_hints.pdf And to a lesser extent the Atari documentation (which has errors) :- http://www.atarimuseum.com/ahs_archives/archives/pdf/videogames/7800/7800_software.pdf Feel free to ask questions in the 7800 programmers section too. With the extra memory added, will it be possible for the 6502 to continue running from the expansion module memory without having to halt when maria is in use?

How much will this gizmo cost... I need to know so I can save money ahead of time and have ready when it's released. I think it would be a good idea to put a USB connector on it for homebrewing.

You know the 7800 needs a pokey or a speakjet sound chip like the one on the Atarivox for better sound quality. Why not add a sound processor to the module? Graphically the system is capable of some untapped stuff, but the sound is still 2600 quality stuff.
