I'll give those a shot. Also, Brad Taylor, the author, just got back to me on this and said:
"for acquiring the contents of a FDS disk from the drive, you may either:
1) create the 16-byte header file. you probably won't need to do this.
2) specify a existing FDS image that matches the # of sides of which the FDS disk game being acquired has. the FDS file's contents will then be overwritten with the newly acquired data. don't forget to hit F2 on exit to update the specified FDS file with the new disk contents.
Creating the 16-byte header has to be done in some sort of low-level hex editor application, but this would only be neccessary if you needed to acqiure an amount of disk side images into a single FDS file that exceeded the amount of other common ones (usually these have just one or two disk side images, with each side equivelant to approximately 64K bytes of data).
The DOS EDIT program can be used to create a 16-byte image, if you enable binary mode on the file open window. Though this will only allow you to use ASCII codes to create the header (rather than hexadecimal digits), you can hold down the ALT key while typing a base-10 number to access most 8-bit ASCII codes. information on how the 16-byte FDS header works can be found at nesdev.parodius.com (look for the "Famicom Disk System" doc by Nori, translated by Ki, under the "1.2. FDS Format" section). "
I actually tried overwriting a Doki Doki Panic image, but It didn't seem to work...actually, the file was corrupted (err 22 when loading it to the Ram Adapter), but it did seem to dump something...
I noticed Brad mentioned to hit F2 on exiting, but I think the docs say to hit F4...that's probably what he meant but I will ask him.
