What is GFX9000?
GFX9000 is a cartridge for the MSX computers and it has a V9990 Video Display Processor as heart. The V9990 is based on the never released V9978 VDP, which was supposed to be in the MSX3. Instead, the MSX turboR was released with a V9958. After the failed project, the compatibility features were stripped off the IC and the result is the V9990, see also the MSX turbo R section. So, in 1994 Sunrise decided to make this cartridge with the new VDP in it. It has a seperate video-(RGB)-output connector. Henrik Gilvad even wrote a special BASIC for it, called PowerBASIC (for MSX turbo R). It enables you to use the capacities of the GFX9000 in your own BASIC programs. An alternative is G-BASIC, written by Koen van Hartingsveldt, which also supports Video9000 (see below) and runs on MSX2 and higher.
GFX9000 is delivered with the following software:
What resolutions, colours and other specs does it have?
(Stefan Boer, Sunrise, Marcel Delorme, me)
The V9990 supports the following resolutions:
|P1||256×212(424)||dualplane patternmode (2 independent planes)|
|B0||192×240(480)||undocumented overscan mode (no borders)|
|B2||384×240(480)||overscan (no borders)|
|B4||768×240(480)||overscan (no borders)|
|B6||640×480||needs a 25.2MHz oscillator|
Resolutions between brackets () are in interlacing mode. Note that overscan modes have 50 lines extra for non-interlace and 100 lines extra for interlace modes when they are used in PAL 50Hz mode. So, in 50Hz, the B4 mode can be 768×290 (non-interlaced) or 768×580 (interlaced).
These resolutions can be combined with the palette systems below, so a lot of different types of screen modes are possible. Systems using 8 or 16 bits per pixel are not possible for B4..B6, P1 and P2 only work with 4 bits per pixel.
|8||64||out of a palette of 32768|
|256||like SCREEN 8 (fixed palette)|
|19268||like SCREEN 12 (YJK)|
|4||16||out of a palette of 32768|
|2||4||out of a palette of 32768|
The modes with 19268 colours are optimized to display digitized pictures with a minimum of memory and no remarkable loss of picture-information (JPG and PCD use similar methods).

What is supported by PowerBASIC?
I don't know if it's changed, but from Stefan's article, I cite the
Screenmodes supported in PowerBASIC:
|0||64 column textmode|
|1||will be 32 column textmode|
|2||P1 mode (256×212 dualplane patternmode)|
|3||P2 mode (512×212 patternmode)|
|4||identical to SCREEN 2|
|5..12||identical to MSX2/2+ except the sprites,|
only 2 sprites in one colour are possible
(this is the cursor-sprites of the B-modes...)
Further, PowerBASIC supports the following BASIC commands for the GFX9000:
What software is made for GFX9000?
Here is a list of most of the software that has been released or is being made for GFX9000:
What is the Video9000?
The Video9000 is an add-on board for the GFX9000, that allows you to digitize/superimpose on MSX2/2+/Turbo-R in the high-resolution of the GFX9000 video-modes. It is developed by Koen van Hartingsveldt of Sunrise.
As said, Video9000 is an add-on board for the GFX9000. So if you want to order it, you'll have to send your GFX9000 to Sunrise, where they will solder the board on the GFX9000. The new card (including Video9000) will then be placed into a new box that includes the connectors and colour/contrast regulators. This new cartridge has to be connected to the MSX via a primary slot then.
What can I do with a Video9000?
With this digitizer you can grab pictures from a video in 32768 colours, superimpose parts of it with animations and titles upon video images, mix your own creations with these video images, etc. Furthermore you can switch from the MSX2/2+/turboR screen to the GFX9000 screeen and viceversa just by one simple command. Besides, you can save directly (without graphic conversion programs) your images in several formats (now Koen is working in more image formats), like: BMP, the known PC format, PIC or VGF (that can be showed with any Graphics 9000). And all this in several resolutions (all in 32768 colours): 512x424 interlaced, 384x290 overscan, etc. The Video9000 board includes a lot of connectors (inputs and outputs). It is possible to digitize images from a RGB source (for example, a MSX computer or a VCR with RGB output), CVBS (from a VCR, videocamera, computer, ...) and S-VHS (from some videocameras). The output is RGB.
