Has anyone tryed to do something on the Vectrex bios ROM?
It would be nice to use some other game in it or even multicart...
Or could the bios be updated with some new commands to make more complex games on it?

Why not? I dont say that it would be common, but i have fully modded all my other consoles too (all Segas, Nintendos, Playstations, Xbox..) And some reguire alternative BIOS to play other regions. Its not hard to add one chip holder there. So i suppose it might be possible to create "multicart" with switch in the console? Or just to replace the built in Mine storm with some other same size game.

Would this make it possible to make a simple program that reacts to sound too? I would like to see my Vectrex making some lines to the rythm of my music...

Why would you want to change the ROM, when you can boot anything from a cartridge anyway?
I suppose a rythm game isn't out of the question. Each joystick port has two analogue inputs for the potentiometer inputs, so I suppose you could feed sound into there. It would need some sort of regulation though, you don't want to blow anything! But, yeah, once its there it can pretty much be treated as analogue joystick input... I think the vectrex should be capable of a Vib Ribbon type game, if that's what you had in mind.

I just want a different built in game than mine storm  And maby some new features and different opening text. Why is it so hard to get? If i had multicart built in i wouldnt ever need to put another cartridge in to the machine. And i could have rom holder built in there. Also i would want a "screen saver" that can show music, i suppoce cartridge port could be used as input for the sound signal? Im thinking something like this: www.youtube.com/watch?v=fFiQ4bTW8IMAnd im going to make my Vectrex look something like this: www.youtube.com/watch?v=ZhKsjEiG86wBut that Vic Ribbon also seems cool Havent seen that before. |

IMHO it would be better to replace the BIOS ROM with NVRAM. That way you can re-flash at will.
Also, if I were to modify my Vectrex I would increase the RAM size as well.
As for the music I'm not sure the Vec could handle the A/D conversion fast enough to produce sine waves with complex harmonics.
