There were two SDKs supplied with the Dreamcast Development platform. One was a stripped down version of Windows CE 2.1 that supported a custom implementation of DirectX 6.0. The other was a set of low-level libraries developed by Sega. The majority of games released for the console used the latter due to the increased memory footprint of the CE OS, running on a platform with only 16MB of system RAM.
* Windows CE for Dreamcast = " Dragon "
When various information are synthesized, WindowscCe " Dragon " for the Dreamcast, it is thought the package for development which includes description below. In sense of narrow sense, it probably is the small OS for the execution which is included in the GD-ROM of the Sega * rally 2. When the Sega * rally 2 is operational, the WindowscCe is operational in the part of the 1MB of 16MB memory! Even, so far, in a way, common library of the game machine manufacturer, as for the example where those like the OS are moving it was many, but generally known measure the OS and the OS っ ぽ it will be and as for the game machine which moves with the OS, this time probably may call the first time.
Such, being possible, may call one of feature in regard to the design where the WindowscCe Kernel is superior. Therefore, also it is possible to keep installing in the portable telephone and the FAX et cetera.

* It becomes " the Dragon " air, as for the efficiency?
Well, if generally, " you mention the Windows, it probably means that the impression that it is slow ", is strong. It is thought it is the user which from about Windows 3.1 knows the Windows, almost not to be wrong, it has this impression.
The PowercVr2 tip/chip which is loaded onto the Dreamcast, is said they are 300 ten thousand polygon /sec. But, when the Sega development department interview which is published to the ファミ and the like is read carefully, as for this numerical value, the Dreamcast Is not limiting value, it seems. If the number of polygons which can be utilized in the actually game, they probably are 300 ten thousand polygons, with thing, pulls out limited efficiency, as for 500 ten thousand polygons you say whether it is not to be able to go.
On one hand, in order to move the Sega * rally 2, is the number of some polygons probably necessary? As for the Sega * rally 2 of arcade edition, 100 ten thousand polygon /sec which are called Model 3 it was moving on the baseplate which can be put out. You do not understand whether or not in arcade edition, 100% it emptied out this baseplate, but in Dreamcast edition, in order to achieve the quality which almost is equal to the Sega * rally 2 of this arcade edition, it is visible.
However, you do not understand in the amateur eye, but when really you hear in the game developer of the Dreamcast and the people who have development experience, " (the Sega * rally 2) is rather painful, is, well. The frame falling is visible ", it seems. As for the same phenomenon as this, with the SONIC Adventure which utilizes " the Ninja " library of Sega there is a possibility efficiency about of half of the Dreamcast having been lost from the fact that it is not seen, after all, by " the Dragon ".
Furthermore, at the time of communication opposition, sound playback of part is lost, because (it has turned off completely, breaking off, you hear and the painful wind is seen and so on is not), degradation after all.
* It was hard labor? Dragon
By the way, sale day of the Sega * rally 2 was at the beginning 11/20, it was schedule of simultaneous sale with the Dreamcast.
Adjusting to the sale postponement of the Dreamcast, it was modified to November 27th in 10 ends of the month.
It made January 14th sale before the November, on year end, furthermore was postponed to January 28th, finally, this each time reached to sale.
Furthermore, the Dragon, it is thought the source cord/code and the like of the library is not open with the example of the Microsoft product. Because completely the lapping it is done by WindowscCe API, when the game moved well with this, the Windows98 There probably is a merit that it can be done also the transplantation to above and the like easily. But, shipment of the game software to be supreme proposition in present condition, the PC From the software house which does not expect many to the business game market excessively it cannot ship the game with bug of the すると and the library, how, it is outrageous situation.
* Summary
Because there is such problematical point, perhaps, the software house which with such as action system adopts the Dragon and the sport * simulation game where high speed is required it is little.
But, performance the most importance does not limit the game always. Besides the fact that while developing is rumored with " the Dragon " base " to the Hudson of the romantic love type simulation * game north " already, also " the ambitious Dreamcast of trust length " of the コーエー and so on, is imagined whether it is not to become " the Dragon " base. For the present, also the viewpoint that is possible, it is length of one day in " the Dragon ", at the time of network communicating, future development is the pleasure.
Well, with such, as for end of the WindowscCe based game software and the Sega * rally 2 review, we would like to round off with the communication opposition which becomes matter of concern.

2) ¿Qué repercusión tendría actualmente y me refiero al hecho legal ,, si decidiese usar un kit oficial con una Katana y sacar emuladores bajo WinCE y Libs oficiales ?
