The topic for discussion of the console, modifications, assistance in solving problems in the operation of this console



The history of the console Sega Dreamcast
Sega Dreamcast was the first 128-bit console in the console market. For the first time information on the new console from Sega was leaked to the internet March 12, 1997, with initially appeared the rumor that Sega Saturn was going to upgrade their level to 128 bits. Today it sounds ridiculous, but then many gamers really believed that it will be so, and the true fans were waiting for us, that now a Sega his chance and did not miss the show finally, what it can do. But by 31 March of the same year the situation is cleared up, and the whole world learned that Sega began development of an entirely new console. By June 1997 it became known that Sega is considering two technical project, which, in principle, not so radically different from each other. One project was named Black Belt, second - Dural. Black Belt had the IBM / Motorola Power PC 603 processor with E graphics chipset 3Dfx Voodoo 2. Dural also includes Hitachi SH4 processor with a chipset NEC / Videologic PowerVR 2. Both projects were in their good, but time went by and it was necessary to dwell on one of them. As a result, the project was selected Dural, although the American branch of Sega until recently insisted on the Black Belt. Future console was given the working title of KATANA. Sega also enlisted the support of independent game developers, who gladly agreed to develop games for the new console. Fortunately, the architecture of the new consoles was much easier than that of Saturn. In the development of set-top boxes it involved a large number of world-famous companies, including Microsoft, Hitachi, Nec, Video logic and Yamaha. The console runs on Microsoft software, and it is running Windows CE. The console has been built on a 56k modem, allowing you to play on the network, or just "climb" over the Internet, using the connect additional keyboard and mouse. The prefix 12 regular-speed GD-ROM has been inserted. Dreamcast could handle up to 3 million polygons per sekundu.Pristavka was first presented to the public September 7, 1997 under the name of the Katana, but a year later, at the time of the official release of consoles, the name changed again to all of us familiar Dreamcast. Release consoles repeatedly postponed and has come, finally, November 25, 1998. All 150 000 consoles, produced at that time, were sold on the first day, and the deficit remained on it until mid-December, has not yet arrived next batch of consoles.

The start in America was scheduled for a mystical date; judge for yourself - 09.09.99. The price was set at $ 199. I must say that it met the expectations of the company's management - the prefix was very successfully sold. Sales in Europe began on October 14, 1999, and were also successful. And only in Australia the launch of the console, scheduled for November 30, 1999 was a failure, and even that was mainly due to the terrible shortage of the consoles themselves.

By October 1999, the Sega US branch sold 518,000 consoles in America, by November this figure had grown to 750,000, and by the end of the year it was possible to reach a figure of one million. This pace of sales encouraged the company. It seemed that the second million would not be long in coming.

But happiness could not last forever. Sony, of course, could not calmly watch the success of its competitor and in every way added fuel to the fire, promising that its new console - Playstation 2 - would be an order of magnitude superior to Dreamcast. Sony even lowered the estimated price for its new set-top box, thereby trapping Sega. After all, Sega could not do the same; the cost of the console was too high.

Another alarming bell for Sega rang when many gamers began to show dissatisfaction with the constant delay in launching online games. This was because the project has not yet been fully developed. But still, by January 2000, Sega Net was launched, and 30% of the Japanese were able to enjoy the game on the network. By February 17, this figure has grown to 50%. 300,000 people used the network in America, and 200,000 in Europe.

But, whatever one may say, and since the release of Playstation 2, Dreamcast sales began to fall steadily, and this despite the fact that Sega lowered the price of the console. People still preferred to overpay and buy a better product from Sony. Dreamcast sales continued to fall until the end of 2000, and in February 2001 it was decided to permanently stop its release, and the remaining consoles should be sold at an insanely low price of $ 49.

After that, Sega decided to no longer produce consoles, and concentrated on developing games, becoming an independent developer.

What is a DreamShell?
DreamShell is a Unix-like operating system designed for the Sega Dreamcast game console. Based on the KallistiOS libraries. Originally it was a command line interface, with the ability to run your own applications. In other words, an alternative OS that allows you to run games and applications from your hard drive or from SD to the Dreamcast console.


Console Modifications
G1-ATA (IDE) Connecting HDD to Dreamcast
1 Option The cheapest and easiest, but you need to be able to solder. Open the prefix and solder the cable to the motherboard to which through the optional power supply connect the HDD. You will have both a drive and an HDD.
Option 2 Buy or solder the OzOnE PCB board yourself. You will have both a drive and an HDD, only without a cover.
Option 3 Buy a USB-GDROM Controller board from MNEMO Dreamcast drive emulator. There will be only HDD.
Option 4 Buy a GDemu board Dreamcast drive emulator. There will be only SD.

Comparison:
With almost all GDEmu simply plugged instead of drive it and promptly inserted in the SD card games. Compatibility can be said complete. With regions and selection of games is another story, but like all the inconveniences already more or less flattened inquisitive users. But one minus the fat still remains - is the price. At the current rate it is worth in the region of 8,500 rubles, which seems a little ridiculous. In this case, the SD card is still severely limited in size, and large-capacity flash drives are not cheap, especially good quality, which in general is needed.
Almost the same goes for the adapter from MNEMO, its main difference is that it has USB, not SD, which reduces the cost of a gigabyte. There are still nuances with the format of images and a change of disk for this adapter, but not very critical. The price is somewhat cheaper, but still the order is about the same.

Pros:
1) Compatibility about 100%
2) No installation problems, set instead of the drive and that's it
3) High download speed for GDEmu and normal for MNEMO

Minuses:
1) Very expensive
2) Does not start games in other regions without shamanism (GDEmu)
3) Expensive large amounts of memory (GDEmu)
4) Only supports GDI and ISO (MNEMO)
5) Overhead of interface pairing reduces speed (MNEMO)

With DreamShell, the picture is completely different. Compatibility is certainly not at that level, but it may turn out to be quite enough for a specific person, the main thing is to understand what games are in principle needed. True, to boot without a drive, you need a BIOS mod and this is of course a minus, But this is not a problem if you know how to solder. But there are undeniable advantages.

Pros:
1) It's free
2) A gigabyte of space is much cheaper (or even free, because you can find old IDE HDDs, in principle, for free). You can hook SATA through the adapter.
3) No problems with regions and VGA forcing (where it is generally supported)
4) The download speed of games is equivalent to GDEmu
5) There is a chance)) get extra. functionality that cannot be implemented using iron emulators

Minuses:
1) Compatibility more than 80%
2) You need to be able to hold a soldering iron in your hands to solder a dozen wires
3) If there is no drive, you need a BIOS mod (basically equal to the second point)

More to the advantages of DreamShell.

With the boards of the aforementioned comrades (GDEmu, MNEMO), the console is fenced off, losing its native drive, and after all, many people still have stamping / license collections, to this day people continue to collect.

With DreamShell, it’s just the opposite, when installing HDD, SD-Card, Bios Flash,
the console retains everything that was originally in it, plus acquires new
functions, and these are just the pros in hardware, not to mention the functionality of DreamShell.

In general, if everything is averaged and rounded, it turns out that the difference in money is in fact. A paid solution is simpler and works better, a free solution is more complicated and it still does not work as well as iron emulators, that’s the whole difference ...

At the same time, you get a full-fledged console, instead of one emulator board, which without a console is generally useless.
The main thing here is to understand how critical 100% compatibility is, whether it is worth the money in your case. For some, this may be the main argument in the decision, and if there is extra money, then why not simplify your life And some have both at the same time.

Useful topic, I will attend. I am going to do bios-mod and ide-mod (board from old-console) to my drive. Only now the hands do not reach yet.

* fant29rus,
I have such a BIOS and hdd mod prefix. It’s a chore to do everything, but it's worth it;)

Is power supply on the hard one from the very movie? Also do not seem to recommend?



Rep: (160)
* fant29rus,
This is for short-term tests, and yes, I apply separate power to the hard one. By the way, I saw a modification in YouTube, where after Bios the mod is removed from the main, and instead they put a hard one from the laptop, which is powered from the 5th century. Such food can also be taken from the dream unit.

it is clear, but where do you feed the hard? With comp. BP? I also saw a video ... And on the switch, the question is, which one is needed, how is it in your picture? He was also used for BIOS firmware?

What do you think, move this topic to Other game consoles?

the topic is not lost?



Rep: (160)
* Dyuss,
It would be nice next to Sony and Nintendo: blush:



Rep: (1548)
* pacanko ,
Yeah, even Microsoft has no place next to Sony and Nintendo. The topic is narrowly popular. Or if you want, it might hang here for now.



Rep: (62)
* Dyuss , better section "SEGA". There may be other consoles discuss over time.



Rep: (1548)
* Narcosis-doom
It's too early for such a section.

Drives released later could only play CDs after overwriting the BIOS


the drive is essentially a drum to read, just on the late dreams with the VA2.1 motherboard the BIOS was able to launch the MIL-CD, and on the earliest dreams of the Japanese region with the BIOS 0.74 this possibility was not added yet



Rep: (105)
A very necessary topic! Dream has an honorable right to do this, and in conjunction with Dreamshell + ide mod double: wink_kind:



Rep: (160)
* Dyuss,
Place at your discretion, but so that b, when you drive into the search engine "sega dreamcastsavagemessiahzine.com", it was available in the search results.
By the way, in the other console section there is mega-drive. Maybe all the same 2 is enough for the Sega section?
