FDSloadr Software Not Working

[Ninjanick999]

I made a FDSloadr cable and I am having some problems with the FDSloadr software. I was having some trouble getting it to read FDS ROM files to load, because they did not have headers. I could not find any ROM files that had headers or converters to put headers on to ROM files. I used a hex editor to try to add the header to a ROM. It gets passed the header check, but when the program loads up the DOS screen turns blue, and the Famicom Disk System screen does nothing, as if no disk was inserted. I have tried using the program and multiple computers but none of them worked. Does anyone know what I need to do to get it to work, or any programs that can add headers to FDS ROM files?

Are you sure you added the header correctly? Remember that it's a sixteen byte header, and also contains the information for how many sides the disk has. So, if you set it so that the header says one side, and append it to a two sided image, fdsloadr won't see the second side of the disk.

The documentation on the header format is here:

It's very straight forward and simple.

I'm not sure what you mean about the screen going blue, I've never seen that happen. Are you attempting to run it from within Windows? You should really run it from DOS directly. Also, it needs real hardware to work correctly, the parallel ports on most laptop computers suck, the voltage levels aren't correct. You can either build a buffer board, or use a real computer with a built in parallel port.

Thanks for the help. I got it working. There was a problem with the header.
