For some years I was quite activ in the “vectrex-community”.
I was even in charge of the (than) only vectrex emulator.
Here is the last known version of that exact emulator – and the announcement message when it was “delivered”:
I finally came around and packaged the last known DVE version in a nice bundle. There might be some files that are not strictly speaking “free” – but right now I don’t see any commercial harm. If someone wants me to remove files – please contact me, I will do so willingly.
The “creme pie” is, that it is not only the last version, but I actually got my act together and it comes with the complete full source!
I know it is complete and full und sourcy, because I just did a fresh compile :-)!
The whole package comes as a DosBox setup. Just start DVE.bat – or if you are more in the Mac world (like me nowadays) double-click the “VectrexDev.app” – and my (more or less) old development environment from the good old days pops up :-).
If you than enter Vertex.exe – the emulator boots up.
If you enter “compile.bat” the emulator is compiled. (well now there are no changes, so only a quick link will be done)
The source is in the aptly named “Source” directory.
Paths and compiler and so on are all setup!
I did not put much new effort in documentation, so the docs are scrambled. Be sure to read every scrap you can see in those dirs.
The echos before start read:
Welcome to DVE!
Dispite its age I believe DVE to be a very good emulator with many
capabilities! They are although hard to discover!
Be sure to read thru all documents you find alongside with it.
You will discover many hidden gems (keyboard shortcuts help on click etc)
For example if you start in gui mode (default) and press
the little config button (upper left, like a screwdriver)
the small text “create…” gives you a disassambled cartridge
view, with single step, breakpoint watch windows for signals etc.
The “edit cnt” file (look at the doc) can import symbols from
your assembler. In the monitor window (alt M) you can then
e.g. type: “watch x_step” (if that is one of your variables) and
a watch window will be created. You can also set breakpoints that way!
This is the most complete version of DVE you will ever get!
You can even change and build a new version of the emulator,
sources are included. To compile just start the “compile.bat”.
(to remove this message, edit autoexec.bat)
You can download the file for Windows: VectrexDVE.zip
You can download the file for Mac: VectrexDVE.dmg
Have fun with it.
