In SVI-728 there was one special feature, that has been bothering me many years now. There was some pretty simple (software) trick to switch green color from color pallette to brown! IIRC it was precisely color 12. I remember that this was really cool as other MSX computers didn't have a brown color. Smile

Does anyone have idea, what the command(s) was??? How does this work in hardware vice? Could it be possible that it was done by using VDP under recommended voltage or some other similar kind of trick?

Ps. I really mean 728 not 738 and I've seen it with my own eyes!

I remember it too, something like:


.. and then stand away 3 yards from your screen Tongue
This probably works better on an old tv. Other colour combinations are also possible.

I know that this sounds stupid, but it is definately there... I remember I had just got a new cool game: BMX-simulator from local store and using this trick, you could change the sand color to quite right! Smile

Bit 0 of VDP R#0 (external video input) selects the better looking colors on SVI-728. Smile

Ah, yes! That must be it! Thank you!!! I was already starting to doubt working of my own head!

??? BMX-Simulator was a cassette game and it was actually not that cool...
