dc早期的游戏引导区没加入vga代码,因而不支持vga,所以不可能有支持全部游戏的vgabox,当然d版除外因为可以手工加入vga代码后再重新制作。
至于扫描线功能,国外早有成熟产品,并且是开源的,线路图随便下,可以自己diy,嫌麻烦可以买别人做好的。

官方的说明是,这个vga box有一个开关,可以跳过dc检测,就是一个15  31khz的开关,进而可以所有游戏vga输出,而且在此基础上再使用可以调整粗细的扫描线功能,楼***应该查看一下我说的是否有夸张??

请直接看5.6,官方说明
1. Who is Hanzo?

Hanzo was a legendary Samurai in the Sengoku era of Japan. You can recall him from the Kill Bill movie series and some fighting games too.

2. I meant "What is Hanzo?"

HANZO is a Dreamcast VGA box with built-in scanline generator. A few months ago, when we first started we built these boxes and gave a small run.
www.assemblergames.com/forums/sh ... ewfull=1#post639703
However it took too long to build one, because of drilling and soldering works. So we decided to design a PCB to make it more robust and durable also easier & faster to build.

3. What are the benefits of a VGA box?

Dreamcast natively supports VGA output mode however you need a special cable to enable this mode. So you can play your favourite arcade games in higher (480p) resolution on VGA monitors, modern displays like plasma and lcd screens.

4. I am happy with my RGB Scart cable. Is it worth the upgrade?

RGB Scart cable can support up to 480i, which is interlaced and not progressive as a VGA box. RGB Scart gives only 15khz, however VGA is 31khz, which enables clearer, sharper and more detailed images that you can't get with an ordinary composite, S-video or Scart cable.

5. I heard that some games don't support this VGA mode, is it true?

Yeah, it's true, some games don't support the VGA (31khz) mode. Dreamcast checks the type of cable plugged while booting and it refuses to boot if the game doesn't support the VGA box.

6. So how can I play these games with this VGA box?

It's possible to trick the console to pass this limitation on those games. Our DC VGA boxes includes a switch to let you change between the 15khz and 31khz modes to alter this check.

7. What about audio?
It has RCA Stereo audio jacks to let you plug your console to an amplifier or a stereo system or simply your TV.

8. I heard about scanlines but I am not sure if I need them. Do I really need them?
Modern displays don't give the feel of our old CRT TVs. Old games look better on old TVs,
however your new hi-tech screen gives edgy, pixelated graphics which decreases your gaming appetite. This is because CRTs have scanlines and games were designed for these displays. If you are an enthusiast of 2D fighting games or shoot 'em ups, you will notice it's even worse in VGA mode because of the higher details. Scanliner (what I call for our scanline generator) eliminates this problem by enabling scanlines in VGA mode. So you can play your Street Fighter 3 game in full glory even better than before. To be honest, Dreamcast was never my system of choice for playing those fighting games until I discovered scanlines. I was missing the old days with my Sony CRT. Now I can’t stop playing them on my plasma monitor.
You can find more technical info here: scanlines.hazard-city.de

9. What other features does Hanzo have?
You can turn off Scanlines easily with a switch, you can select even or odd scanlines, you can change the width of the scanlines, thin or thick for a resolution like 1024x768.
It's also possible to use Hanzo as a standalone Scanliner for other consoles/PC with VGA output if you use the extra Scanliner cable, no need for any other Scanline Generators.

10. Is that all ?
We use high quality shielded video cable for better picture quality on our boxes. It has a blue power light. Hanzo name is laser etched on top.

11. How much does it cost?
Hanzo costs $60 excluding shipping. Airmail shipping is $5. Each additional item is $2 more.

12. What method do you use for shipping?
Regular Airmail with tracking number and signature upon delivery.

13. How long does it take to arrive?
About two weeks, sometimes shorter, sometimes longer. It may even arrive in 4 days, if you are lucky or 4 weeks if it’s season.

14. Where are you located?
Istanbul, Turkey.

15. Do you have them in stock?
Please ask for availability.

16. Do you offer any warranty on your products?
Yes, it’s a 1 year warranty. In case of any failures or damages on the product, it can be replaced or fixed if you return it.

17. Does it include any manuals?
Yes, it includes a downloadable PDF instruction manual to make it easier to operate.

18. Do you have a website or blog?
Yeah, we are building one and will launch it soon.

19. What about Kuro?
Kuro was a regular DC VGA Box with headphones jack for audio output and a 15khz/31khz switch. It’s discontinued because of the same reasons above.

20. Will you release it again?
Yeah, it will be build on the same design, it costs $40 + $5 shipping. It has RCA jacks instead of the 3.5mm headphones jack. Photos soon...

21. What about the Scanliner?
Again, same design. VGA(HD15) MALE pigtail cable to VGA FEMALE. Includes On/Off, Even/Odd Select, Width Select switches. It costs $35 + $5 shipping (as above).

22. How can I place an order?
Please reply in this thread to place your order and I will PM you for payment details...

23. How big is it?
It's very small, about 2.3x2.3x0.59 inches or 5.8x5.8x1.5cms

vga部分没有缓冲芯片,那2个集成块是制作扫描线用的,其余部分和国内那种vga线一个路数,不过多加了3个电容1个二极管几个电阻。
至于那种强制vga输出的办法,在vgabox时代就有人用过了,还是有不能玩的游戏。

不清楚。我用的是treamcast牌的vgabox+自制的扫描线发生器。

DC GDEMU光驱板本身可以开启强制VGA输出。

原生480I游戏可能动画黑屏,游戏正常(恐龙危机),黑屏的原因不排除动画是低解分辨率或其他。

原生240P低解游戏强制VGA绝大部分显示器是不支持这个分辨率的,所以黑屏。

另,修改使低解游戏以VGA模式显示我见过一例WORLD NEVERLAND PLUS,画面缩在中间很小一块。

不得不说DC在输出兼容性上真的是台烂透了的主机。
