writing an IPF to floppy disk
« on: October 14, 2008, 09:44:43 PM »
Any chance to write an IPF to floppy on an 68000? WWARP needs at least a 020.

99% of the time it is not currently possible to write IPF images to disks no matter what CPU you have.

Neither the software nor the hardware exists to do it.

However some IPF images can be converted (using UAE) to ADF or Extended ADF and then written back to disks but not many.

P.S. What has WWarp got to do with IPF images?

Um... what's the use of it then?

I found a script on EAB that uses wwarp to convert ipf to adf.

None for the real Amigas. You can load up ipf's in winuae with a library, but nothing more.

hm, I heard some use it to fool whdload in UAE..

It depends on type of used copy protection whether you can write them to real floppies ATM. If you got the original disks that are slightly damaged maybe you can copy those (not copyprotected) tracks from .ipf to it with that adf conversion already mentioned. (IIRC they sometimes protected only bootblocks with loaders)

BTW, I would love to have a way to backup&restore originals that I have but none of those utils (mfmwrap and similar) could do it.

Basically I wanted to check out some of the Amiga games that weren't that are available in IPF format.

What games is it you want? If it has a WHDload install that makes a full 880 disk image you should be able to write it back to disc. I havent check if these games even have any copyprotection.

Edit:If its Snow Bros there is an ADF.

hm, maybe that "flash card floppy drive emulator" project would one day work with .ipf (besides .adf that work now) on real Amiga

Emulation. Use with WHDload to make HD installs.

How?

You fire up WinUAE, boot from your emulated hard drive to workbench, insert your IPF image into DF0: and use one of the hundreds of ADF programs. I tend to use ADF Blitzer

Not sure if it is included with the WinUAE install so you might need to download the SPS user library from http://www.softpres.org to enable IPF support in WinUAE

The HxC Floppy emulator project supports ipf files (and Pasti/STX file):

You should point out that to do so it uses the PaSTi and SPS plugins and most of the credit should go to those guys.

Still very cool though. Forward thinking to add plugin support to your server.

When you can support PaSTi and IPF stand alone then it will be cool!

Sorry but i didn't use the PaSTi plugin (ijor didn't release anything about the specs of his file format and his  plugin dll !!). I had to reverse engineer his format and make mine own loader.

Regarding the ipf format (and pasti), the standalone version already support it !
And Alexh the variable bitrate in track mode is not a trivial problem, so i think i deserve the credit ;-).

wow, it has support for so many computers, Jeff_HxC can you add "ZX Spectrum +3" and its .dsk?

wait, I just saw "Amstrad CPC6128", so it would work on +3, right?

do you sell DIY kits?

And if what you're saying is true then you'll get said credit.

If you understand how IPF works, can you document it? There are many ports of UAE to embedded platforms with no IPF user library. Xbox, Wii, PSP etc. You should be able to explain it so that we can create our own open source IPF plugin for other platforms.

You don't understand : i didn't hack the ipf file format, i use the regular library to convert them to the standalone hxc floppy emulator file format. ( it's the same process for other file format : ADF,DMS,MSA,ST,etc).

Have a look to the software. (just drag&drop any floppy image to the app window, or use the command line version to convert an entire folder)

@orange: yes it should already support the zx spectrum, but nobody had test with it as far i know.
