You can see when two vertical lines are close to each other, blue and yellow colors appear. I wrote a small Basic program to show you: When TV has to show two black vertical lines on white backgroundĭistant only 2 or 3 pixels, some unwanted colors can appear. I attached a picture from TV (left) and ZX-VGA-JOY(right)
On TV look like there are some colors but actually that is an only TV signal It is black and white on TV and on ZX-VGA-JOY. The multicolor effect in the gameplay at all. I don’t know if there any other version of the game, but this one has no I had trouble to loading it but I found the way, I purchased DivMMC Pro one (nice product). Version v1.03 will be replaced with v1.03a due to a problem with the booting!.
#Sinclair zx spectrum graphics funny update
micro USB connector (under top cover) for firmware update.Compatibile with all Sinclair and Amstrad models.Kempston Joystick interface (can be disabled/enabled).
It is not necessary to do any modification on the original computer as long as the expansion port is functional on pins used by ZX-VGA-JOY.Ħ40×480 50Hz, 640×480 60Hz, 640×480 75Hz, 640×480 85Hz and 800×600 60Hz with 3 different zooms ZX-VGA-JOY is compatible with all Sinclair and Amstrad ZX Spectrum models and probably with a number of clones. This interface is not signal converter, it works in parallel with internal graphics IC(ULA) taking video data directly from CPU and provides crystal clear picture on VGA monitors.Īlso, the picture on VGA monitor is precisely synchronized with PAL signal generated from ULA, so games that are relying on ULA timing looks as they should. ZX-VGA-JOY is ZX Spectrum interface for connecting any kind of VGA monitors, Kempston joystick and computer reset.
