Title: fat95/adfblitzer
Post by: TurboG16 on January 22, 2006, 03:36:20 AM
I heard there is a way to get download .ADF game files working on a real A-500 But im confused do i need to use the ADFblitzer or is it this Fat95 thing

The .ADF file extension is in fact an image of an AMIGA DISK...

No FAT95 involved...

Basically, what you would need to do is recopy the .ADF to a FLOPPY using the A500, this can not be done on an IBM COMPATIBLE due to Hardware limitations...

Progs to use, ie. ADF Blitzer, check AmiNet

If you downloaded your .ADF files with your A500 then you only need ADF Blitzer (http://de4.aminet.net/disk/misc/adfblitzer.lha).  You'll only need FAT95 if the .ADF file is on a PC and you need to transfer it to an Amiga so that you can use ADF Blitzer on it.

Can you post the specifications of your A-500?
Does it have a Hard Drive?  Do you have more than
one Floppy Drive?  What OS are you running?  Most importantly do you have crossdos working so the system
will recognize PC Dos disks?

A listing above asked if you downloaded the file with
your A-500 but I suspect that you don't have your A-500
on-line / networked.  That would be quite an A-500 !  Certainly not impossible but it would clearly need to have been expanded (like my waistline) to have that machine
on-line. Like an accelerator, HD expansion, ram expansion, etc.  

Anyway, if your A-500 is running workbench 2.5 (??) or higher I believe that CrossDos is built in.  You need to drag the PC0 or PC1 icon from storage into Devices/Dos folder (I think ). That way you can put a low density PC formatted disk 880K into your Amiga and have it read it.

Sooo . . take an 880K amiga disk (I assume you have one that you can sacrifice) format it in your PC and move the adf file to this disk.  Take the disk from your PC and put it into your Amiga 500 and hopefully you will be able to see it.  Run ADFBlitzer and write the file (hopefully) to your 2nd floppy drive.  I'm sure there is a way if you only have one FD, or if you only have one FD and a HD you can move the ADF file to your HD and then use ADFBlitzer to write to your FD.

Good luck - certainly a fun project.  Also if you want to get facny you can get Amiga Forever 2005 a nice emulator for your PC.  You basically convince the PC that its an Amiga (configured any way you want  . . like a basic A500 or a top end machine).  The emulator reads/loads ADF files as a part of the set-up so it is quite easy to run all the old games and programs.  Not quite the same as having it run on a REAL A500 on a 1084S or TV monitor.

I always thought that PC's couldn't read and format
Amiga 880K DD disks...:roll:On the other hand, it's
possible that Amiga's could read and format PC disks though...Someone correct me if I'm wrong.

The PC can NOT read the Amiga format disk.
However with CrossDos running the Amiga CAN
read a properly formatted PC disk. You just have
to be mindful what kind of Amiga drive you have ->
Low Density or High Density Drive, and format the
disk accordingly.

Anyway . . .
You take an old Amiga 880 disk and stuff it into your PC. From My Computer you can right click the disk (sometimes when an un-readable disk is inserted the box opens automatically asking "do you want to format the disk")  There are options for high density and low density floppy format.  Just use the drop down and you can blow away the amiga format and make the disk a PC low density disk.

Since I can see you are an Amiga 4000 man you can actually read a regular High Density PC disk in the High Density A4K floppy drive . . . asumming you have CrossDOS running.

Bye bye

Yes, I know that I can use HD PC disks with my A4000
& even with my A630 with original Chinon 1,76MB HD FDD.
But I never needed CrossDos to run though...
I think you mean that if the PC disk is PC formatted,
then I would have to run CrossDos in the background?
OK, but I never use the FDD for file transfer between
PC and Amiga. For that purpose I use cd-roms or compact-flash cards with the PCMCIA2CF adapter...

after all in the pc the dd disks are 720kb and if you have winxp you can't format a dd disk anymore... you do it in the amiga (!) and then you use it in pc. :lol:


-edit-
@Amidude: is it easy for someone to find one of this pcmcia cards? i didn't even know that exist... :roll:

720kb...That's too little capacity for any serious
file-transfer! :lol:

You can find PCMCIA to CompactFlash adapters in many
electronics or computer shops. They're also frequently
for sale on eBay.

You can do it, but not from the formatting GUI.

Open a command shell (a.k.a DOS prompt) and type the following:
format a: /t:80 /n:9

This will format a 720Kb disk of 80 tracks and nine sectors per track.

Oops that is correct.  It is only 720kb on the PC. I believe that Windows 2000 still allows the low density format from the GUI but WinXP does not (I just checked).  Otherwise the PC DOS command shell is needed as amije says above.  With the crossdos running you can indeed format the disk PC style on your Amiga straight away.

Wow an Amiga 630 with a HD drive.  That is cool ! The one I had only came with the LD drive.  

 >>> Keep in mind, though, our "curious" friend that started the thread has some sort of A500 and is probably limited with the periphials that he/she can connect with.  
ie No PCMCIA card or CD Rom. No specifications listed.  If they had a SCSI sidecar HD with passthrough they could add a SCSI ZIP drive and transfer large files that way.
They just want to transfer over an ADF file probably for a self booting game or something.  Hey "curious" you still out there? :-P

I believe you're referring to TurboG16!

I had a discussion with him in another thread - seems he's got a stock A500 with no Workbench disk, and therefore no easy way of getting stuff to/from Amiga disks.

Yup - TurboG16 the "merely curious" person.  I figured he would have a challenge with the task at hand.  Hopefully you gave him some good tips.  Getting a set of Workbench disks and a spare floppy drive would probably get him going.

Hi TurboG16, in short, it's possible, but you are always going to be running into the same problems with transfering files from your PC to your Amiga.  It would seem you haven't yet solved this problem.  As mentioned above, the .adf file can be transferred to a real Amiga disk, but this can't be done with only a PC.  The file has to be written to an Amiga floppy disk, residing in an Amiga floppy drive (assuming you don't have a catweasle).  If you need more help with this problem, let us know.  My advise is to go back to the person you bought the computer from, and ask for some help.
