Tunerpro bin stacking

[kelvin]

I'm trying to put a VN bin on a 27c256 using the Tunerpro binstacker. I may have a misunderstanding with bits and bytes.
The way I see it is the VN bin is 16kb (bytes) or 128k bits. The 27c257 is 258k bits. So I need to stack it on top of it self once.
In the parameters for the bin stacker I selected 16KB as the bin size, 256KB as the chip size and 128KB as the block size. When I press the 'stack' button, it comes up "Could not create output file". Have I missed something else?
And if I finally get it working do I then just save the file using 'save as'. Which I assume would then be a 32k file.

ok forget about bits, the stacking tool is entirely in bytes.
you want to set 16k bin size 32k chip size 16k block size. hit the 3 dots to the right of the output file and name the output file, then choose the same bin for both input files and click stack, it should work.

Thanks heaps for that. It works, but stay tuned, I'm sure I'll be back.
