Hi, I am new to 7800 dev, but have done lots of 2600 development. I was trying to assemble Dan B's sprite demo (the one on his website) using the same command line as I use for 2600 programs (dasm name.asm -f3 -v5 -oname.bin) and I got a file that was 0kb How am I to assemble 7800 programs? Also, How do I sign them with a78sign?

I never used the -v option in DASM.
For a78sign use:
a78sign -f game.a78
If it's not a bankswitched game you can use a bin file instead of an a78 file if you prefer.

How am I to assemble 7800 programs? Also, How do I sign them with a78sign?Your command line is correct, it's my code that is wrong!
Replace this line:
SEG.U code
with this
SEG code
The .U tells is not to generate anything in the output file. I am not sure how I managed to compile this in the past.

I found another problem in the code that would prevent it from working. I am not sure what I was doing when I put that code together!
I have put the updated version on my web page:
