[Trident]

I've done a lot of flashing and even used a few Kitchens (including Calkulin's) to make some ROMs, but I can't even get this one started.
I get the COMMAND window open. I get to the point where I select what type of ROM I want to make for my DIAMOND and then I get the error for all options. "Missing OS.nb.payload from ROM folder"
I extracted a file with that name and put it in the folder called .ROM, but that didn't change anything.

I'd also like to know how to be able to use different SYS files with the kitchen. I remember that in older kitchens, we just put the whole RARed file somewhere- but it looks like the SYS files that are there now are not compressed. And I don't know how to select one or another from within BuildOS. Or should there be only one in the folder.

Thanks for any helpful responses.
