Hi!!

I've created this small program. It's only for MSX Nextor by Konamiman.

Here you have a video demostration.

More Info and Download here.

I hope you like it!!

Very nice! This should become a standard part of Nextor.

Neato! How does it work? Can you provide source code? If you share then programs like VGMPlay and SofaRun may also gain support for it.

I once tried to implement this using _FFIRST / _FNEXT, they store a lot of the filename bytes in the various fields of the FIB, but a few are missing so I couldn’t make it work.

So I think you’re using sector access?

I would be good if Nextor gained some calls to support this natively.

The source code is in the SRC section of the same Github acount.

Yes. To read directory and FAT

Thank you Victor!

Does Nextor corrupts the FAT like DOS2 when deleting a long name file?

Cool! I should’ve looked better :).

What’s the license for this code? BSD or MIT? In other words, can I copy bits and pieces freely when needed?

You share everything you do... so, you can do what you want. If I can help you, just tell me.

Freaking awesome! Victor, do you have any idea of the code size just for the FAT parsing / etc... to retrieve the long file names (as I do not have too much memory left in SofaRun).

And... must say I still hope that this could be integrated into Nextor natively (with an extra new MSX-DOS 2 function to retrieve the long file name for a given file handler).

well the code of Long file name is not too long, but you need at last a buffer of 1024 bytes to read 2 directory sectors... but the code is really short...

That would fit with no problem in SofaRun.

Have you tried to contact Konamiman about what you've done ? Or maybe he's already reading us

Thinking about that, haven't the sources of Nextor been made public ?
