Aren't 3.5" floppies are about to disappear for good? Why develop something for a to be dead medium?

[IFW]

Yes, they are.

Because it is useful since the technology is not obsolete for your needs.

Will a person with 10,000 rare records toss them away if his record player breaks?

He would transfer them to IPF format

[fiath]

Hehe - Actually very possible, but I don't think we want to branch into music any time soon - our scope is big enough!

[wlcina]

Everything what is readable is writable ;-)

what about medium (cf card or USBkey or something like that) with interface (some chips processors or whatever (i dont know)) connected directly to amiga fdd connector. You can write IPF image to card , interface read them and send data to floppy connector like normal floppy drive. maybe this is my dream only :-)

[IFW]

...just you may need specialized equipment to write it
As for the other may not be just a dream.

I have not yet, just need a new cartridge for my Kenwood Turntable

Kenwood? All the true record fanatics use Technics turntables (except the rich suckers who have turntables with granite bases)!

I never invested a dime into records, spent quite a few on tapes (long term waste of money) and also purchased quite a few cds.

I did have a technics, direct driver instead of belt driven but like a fool I needed some cash and sold it

When I purchased an all-in-one system I went with a mid-range Kenwood system

Oh how many friends I had that purchased bling bling one week only to sell it at pennies on the dollar the next

Kris Kaspersky has written "CD Cracking Uncovered: Protection Against Unsanctioned CD Copying", published by A-LIST.

I hope not being off-topic here:

I think a software solution to write back some IPF images back to disk exists right now on a real amiga, by using Psygore MFM2WWarp tool.

This tool supports capsimage.device and is able to "convert" IPF files to WWarp files (a format that Wepl invented for his warper, and which has been greatly enhanced to support some widely used MFM format).

Stupid example: suppose you dump a standard DOS game. MFM2WWarp converts IPF image to WWP file. To write it back to disk, use the WRITE command of WWarp
(maybe a FORCE DECODE command should be done on the WWP file)

Less stupid example: take Leander, Red Zone (a working dump!), Prime Mover, Alien Breed II AGA, Body Blows Galactic IPF files and convert them to WWarp. WWarp can write those known format (Psygnosis MFM 1, 2, ..., Rob Northen MFM, Rainbow Arts Turrican format, and some others) back to disk and the copied disks boot on a A500! Better: copies are copiable with XCopy unlike the original disks (no more '7' longtrack error).

Ok this is not a 1:1 copy but the game MFM loader cannot see the difference.

I heard that RN protection tracks can be written back to disk using MFMWarp (someone told me he copied RN track from Cool Spot), but not with WWarp, so that's still to be done...

[dlfrsilver]

hello JOTD !

So what do we have to write as command line under cli to write back?

thanks for your reply, i think it will greatly help some people here.

What percentage of games do you suppose could be 'remastered' this way?

Also, what benefit do you get from using disks written this way instead of simply writing back ADFs?

That's not true.

Whilst Technic's 1210's are the best record decks for DJ's let me repeat that: The best for DJ's.

For the same money you can get a better sounding record player for listening to music at home. Yes, for losts of money you can get even better ones with granite bases.

With Technics you are paying more for the mixing abilities and workhorse night-after-night reliability rather than the actual sound they produce.

[IFW]

Leander is a bad example each disk holds a Protec track that requires extra hardware to master, that track really must be long as it is the protection track, the rest will be ok.
Most Psygnosis stuff has at least one Protec track that the game checks sooner or later and misbehaves if missing. Exception is afair Walker and Lemmings titles, they used Copylock instead of Protec.

btw...
Red Zone: who has a good disk? Do you know exactly which version does not have the mastering error?
Finding a good Carthage took a few years, maybe it would be easier with Red Zone if we knew what we are looking for exactly...

[alexh]

I provided the NTSC version and that had the manufacturing flaw too didnt it?

[fiath]

Yes, I think so.
