[Apple II/e] Most .po disk images fail to boot

[Newsdee]

The Aplle II FPGA core uses .nib internally to represent floppies.
This format is almost identical to .dsk except that it adds a volume label (so .nib is better for some multi disk games). Both formats are raw track data .

The files .po or .do indicate a ProDOS or DOS disk with data sectors stored in a certain order. So you can't just rename one into the other.

More on these and other formats here:

I'd love to see .woz support on the core but its a lot of work for marginal benefit.

Maybe so, but if in practice it makes a game work, I will take that

I'd love to see .woz support on the core but its a lot of work for marginal benefit.

There are over 1100 .woz files in my collection, many more online. Most games are covered by other disk formats, but I haven't tested them and it could be that sometimes .woz is superior and/or the only one working. And over a hundred Edu programs are .woz exclusive.

At the current state of the core, it would be possible to convert .woz to .nib on the fly via the ARM layer, which is a lossy process but will work as long as the disk does not have special copy protections.

Ideally speaking the FPGA code should natively understand the .woz format (and convert every floppy on the fly to that); but that's a much harder undertaking.

Can you not use the HXC software to do a btach conversion of your entire directory ?

Only took me less than a minute to convert all my Apple II images to what Mister needed.

Thanks...I've looked into .woz conversion before but never tried the HxC (not sure if it was available back then). It seems to work...sometimes. Out of my sample batch of about 10 games only 2 or 3 work. But maybe I'm doing something wrong.

I have a real Apple IIe, and I had to convert all my images to the format that an Apple IIe Gotek drive could read, and so I used this software to batch-convert the lot. So far, haven't found anything that the Gotek can't read. For my Mister, I converted all the .dsk, and .do images to .nib. So far, they all worked. But my collection isn't as big as your "Apple II - Play It By Year Collection", it's around 1700 images, and that includes the multi-disk games.

Maybe the Gotek firmware adds some translation layer and makes things better? These kind of things are above my pay grade thou.
