Creating your own IPFs

[BarryB]

I make most of my own IPF's with Disk-Utilities, it's a great utility for the common formats and some not so common ones too, plus a good way to authenticate your streams and dumps are good. But, as kaffer says, no new formats have been added for a quite a while as Flash Floppy is now full steam ahead

[chip]

Thanks for the info DamienD

I really hope you will remain in this forum

Now i can use both IPFs and RAWs files

Good, searching is began

[chunky_tesco]

Can someone post ipflib42_linux-x86_64.tar.gz to the zone? the softpres download seems to be corrupted when I download and try to run the tar command.

[Retroplay]

Yeah the files are corrupted.
Try the files I've put in the zone.

Thanks for that, seems to work now. Managed to create an ipf for the Uridium 2 Demo on Amiga Format 54b!

[Retroplay]

Excellent.

By the way, the SPS library is only used for reading IPFs, as it does not support creating new IPFs. Hence that feature is implemented wholly within the analyser library with no external library dependency.

[BarryB]

The 'probe_all' feature was useful, it identified Gazza II protection and Star Goose! format as being the same format as Apprentice, Denis says it's the CHW family, so that's 2 more crossed off

[Retroplay]

Yeah I managed to produce an ipf of Night Walk this way (I know, crappy game).

"Night Walk"
    0 amigados
    1 ignore
    2-6 eye_of_horus
    7-84 amigados
    85-159 eye_of_horus
    * ignore

Unfortunately some streams (Domination) have unidentified sectors, ST longtracks perhaps ?

[BarryB]

Yeah, not all formats are supported! I have a few with ST type sectors of 256 bytes for the protection! You can try raw_dd on those tracks and see if that works, while it's just a raw format it does actually work on some unidentified formats!!

You could also try:

"Night Walk"
    * amigados eye_of_horus

Anybody else have problems compiling Disk-Utilities with GCC 8.1.0 ?

Looks like a code bug. This sizeof thing can backfire if it is a pointer. Gcc 8 just happened to detect it and issue a warning tgat became an error. It doesnt seem safe to ignore it. Where can i download and have a look?

[Retroplay]

It's on Github.

I raised a support ticket at SPS, issue fixed.

It's a harmless idiom. Looks like need a cc-option-add line in Rules.mk to disable this new warning. I might have to install GCC8 and fix this I guess, unless someone wants to make a patch and issue a pull request.

Now fixed.

Thanks. .

A few more formats have now been added to Disk-Utilities.

Courtesy of Abaddon, he has now supported the following formats in his branch of Disk-Utilities:

Ninja Warriors (ninja_warriors)
Saint Dragon (sales_curve)
SWIV (sales_curve)
Turrican 3 (turrican_3a, turrican_3b, turrican_3c) turrican_3c holds the format for the saved scores/options!

Currently pulled from: https://github.com/kkrellwitz/Disk-Utilities.git

kaffer has also merged ninja_warriors, sales_curve & turrican3 into his master: https://github.com/keirf/Disk-Utilities.git

He's also supported Ben Herndons HLS protection on TV Sports Football/Kings Quest series and updated the rnc_hidden format!

Really great tool, first time i see it: can extract files from NDOS ADF, too?

No, Disk-Utilities is just for creating images of disks in formats like IPF, SCP & ADF, it's not a disk editor and to extract files from NDOS disks you would need to disassemble the loader I would guess!

Like i suppose, it's a work for hard amiga coders only!
