You hit the nail on the head.VGA is a joke. They have no credentials
whatsoever to be grading video games. There is a very well known
authentication company launching their video game grading dept in 2013. On
staff they have two former Nintendo employees,and individuals who have
worked in manufacturing, packing,and shipping video games. Their name alone
will put VGA to rest. Time to get rid on those VGA graded games folks!

Trust me , people will be breaking those cases open to be regraded. This
company has a huge name here in the states. They will be offering a more
qualified system as well as more affordable prices.

@ Frank Flow , It is way too late for another grading company to take
over VGA … Most of the grails / retro gems are already graded by VGA.

@dontblush33 The cable is an adapter which switches your Dreamcast's A/V
input from a composite to a VGA input, whereas the box is an adapter that
switches your Dreamcast's A/V input from just a composite to a
composite/VGA/S-Video input, where you can switch between the three. Keep
in mind you still need the actual cable (this is where it gets confusing)
because the VGA cable shown in my video is just an adapter, so you still
need an actual VGA cable to go from the adapter to the TV/Monitor.
You interact with the game via the controller. As each specific part of the
game is requested, the application code and hardware-render geometry are
loaded into RAM, while the video and audio portions are usually streamed
directly from the CD. The PowerVR chip coordinates everything. In addition
to processing graphics, it receives the input from the controller, pulls
the data from RAM, sends it to the CPU and directs the use of the audio
processor. You are beaten by the game and turn it off.

@mook5555 Hmmm, I've never used a 3.5mm-to-RCA cable, but I think it should
work. I'm not 100% certain, but I suppose as long as the TV/Monitor
recognizes the RCA cables and plays the audio from them while on VGA
display, it should be fine. Try switching into VGA mode(if TV) while having
something plugged in via RCA cables and check that you still hear audio.
Component works that way, but I've never really given it much thought. I've
just been using headphones with my DC lately.

Yeah, some of them won't boot up with VGA. Off the top of my head, I can't
remember how many, but I know some good ones won't. I would recommend
getting the box version, that says it has RCA/Composite, S-video, and VGA
options all in one box. That way you can just switch over to S-Video or
Composite for any games that don't work. It's more expensive than just a
VGA cable, but seems like a better choice for someone focusing in on
Dreamcast collecting.
o lower production costs, the graphics processor is combined with circuitry
to control the system through a single application specific integrated
circuit (ASIC). Simply put, this means that a custom chip is created to
manage all of the necessary components that would normally be handled by
separate chips. The Dreamcast sound processor is another ASIC; it combines
a 45 MHz ARM7 CPU and a Yamaha digital signal processor (DSP).
The ARM7 is a 32-bit RISC chip that handles all processing of the
compressed adaptive differential pulse code modulation (ADPCM) audio
information in real time. ADPCM is used to sample analog information,
compress it at a ratio of 4:1 and store it in digital format. The Dreamcast
has several hardware effects that are handled by the PowerVR chip. They
include alpha blending, perspective correction and mip mapping.
The Dreamcast is the first console that has a built-in 56 Kbps modem. It
was added to enable online play over a phone line, allowing users to play
games against each other across long distances. In addition to the built-in
modem, Sega is working on a cable or DSL external modem. Broadband networks
are being developed that will take advantage of such a modem and enable
fast online games for the Dreamcast.
Another 8 bits are used to create a gray-scale mask that acts as a separate
layer for representing levels of object transparency. How transparent an
object will be is determined by how dark the gray in the alpha channel is.
By making an area of the mask dark gray, you can make an object appear to
be very transparent; by making it light gray, you can create special fog or
water effects.

I think there's only like 8 games world wide that won't work on it. I don't
remember them all but I do know that they all sucked anyway and 99% of
people wouldn't have played them anyway, except for Skies of Arcadia, that
one is good but won't play on it. Also, a lot of early games like Sonic
Adventure DO support VGA, even though the case doesn't mention any
compatibility.
Mip mapping is a cool process. It is a form of texture mapping in which
different sizes of each texture map are made. In essence, the processor
replaces the appearance of an object with a more detailed image as you move
closer to the object in the game. Let's take a look at how Dreamcast uses
these maps in trilinear mip mapping:

i really want to do this but i heard that some games wont boot up with vga.
A shame really, i have over 65 dreamcast games all originals and a couple
of imports and a boot disc...is there any way to byass this so i can play
all my games? Because if there isnt a way then it aint worth it. i'll just
stick with my s-video...
Like the N64 and the PlayStation, the CPU in the Dreamcast is a RISC
processor. RISC stands for reduced instruction set computer, and means that
the instructions and computations performed by the processor are simpler
and fewer. Also, RISC chips are superscalar -- they can perform multiple
instructions simultaneously.
The system calculates the distance from your viewpoint to an object in the
game. The system loads the texture maps for the object. Our three maps will
be 64x64 (large), 32x32 (medium), and 8x8 (small).The system determines the
exact size that the image map needs to be. Let's say 16x16 for our example
here.
Alpha blending uses the alpha channel to add transparency effects to an
object. This is a special graphics mode used by digital video, animation
and video games to achieve certain looks. Essentially, 24 bits are used to
define the red, green and blue amounts, 8 bits each, needed to create a
specific color.
Based on the size, it decides which two texture maps to use. For our
example, it will choose the medium and small texture maps.It will then
interpolate (average) between the two texture maps, creating a custom
texture map that is 16x16, which it then applies it to the object.

@GamingThroughTheAges thanks for the reply. i hooked my dreamcast up to the
composite/RCA ports & switched into VGA ("PC") mode but I couldn't hear
anything... my TV said "no PC detected"... I think that the sound might
work if I had something plugged into the VGA/PC port.
When a game is put in the console, the following happens: You turn the
power on. The disc spins up to speed. While the disc is spinning up, the
console loads portions of the operating system from ROM into RAM. The game
initialization sequence is loaded into RAM.
This combination of capabilities, performing more instructions
simultaneously and completing each instruction faster because it is
simpler, allows the CPU to perform better than many chips with a much
faster clock speed.

i do not think i would find one vga box in my country,im sad i bought a tv
without vga cable support,will a composite to hdmi upscallers do the job as
good as a vga box?

@tytarian Dreamcast on a 58" plasma! Dayum. That's awesome, but I bet the
pixels must be freaking huge, and especially noticeable if you don't turn
down the sharpness.

@GamingThroughTheAges So if I were to get the VGA adapter, along with the
actual VGA cable, and a 3.5mm-to-RCA cable for audio, I would good to go?

@mook5555 Yeah, I think it might as well, but it's hard for me to say
without actually trying it out unfortunately.
