Nope, I've never been able to find an image of any of the GFX9K companion disks. Mine broke long time ago, in fact half of the disks arrived to me faulty
In the Sunrise's download page there're some LZH archives; but although I've tried to rebuild the disks I'm not totally sure of what's going on, most of the BASIC programs I try don't work.
COPY, BLOAD, LINE, SET PAGE etc. works like in normal MSX2 BASIC there are just more videopages available. There are some differences in MSX1 screenmodes. Check out MSX-FAQ: http://www.faq.msxnet.org/gfx9000.html
There was also some other BASIC implementation, that had custom commands for GFX9000, but I don't remember the name anymore.
Anyone?
That would be a GREAT idea!. Some time ago, soon after receive my unit I emailed Sunrise about the faulty disks set; but never received an answer....
Oh, and the supplied RGB cable was faulty too, the red line seems that it's partially loose and sometimes I lost the red channel....bad luck all in all
Done, I've resent them my old email to sunhisan(A-T)euronet(D-O-T)nl. I've also asked about the copyright of the images and if they can be uploaded to MRC. Let's see...
