WWARP support under winuae

[dlfrsilver]

There is one great thing to do, if you'd agree to correct that :
WWARP doesn't work in winuae because the tool tries to calibrate drive speed
via DMA.

Can you try to fix it ? (Since the track length can be specified, winuae should be able to calibrate onto the max length).

What details can i bring out to you toni to help ?

Example that works on real Amiga and does not work in emulation, including ALL required files.

Note that if this tries to play with motor speed tricks = forget it.

Ok let me explain it like this :

On real amiga, a drive has a max data writable length capacity.
When i launch wwarp, it determines that my drive can write up to $3182.

Since winuae support floppy_write_length, could it be possible to winuae believe
that when using wwarp, the floppy write length used is the value wwarp wants ?

It would simplify things, so that you should not need to emulate any motor speed tricks
like the one used on RNC disk for example.

Wwarp is mainly used to write back MFM protected games with longtracks.

Winuae in itself is not crashing, so i have no files to give you.

Why not just write non-Amiga program that simply creates extended adf file with correct data directly? You would get exactly the data you want.

I'm not a coder, and it would be so great to use wwarp under winuae

[Toni Wilen]

Ok but back to my original reply: you didn't post files, command line examples or anything at all. I am losing my interest quickly if I need to ask obvious things..

[dlfrsilver]

i use this command under CLI : wwarp nameofthesoft.wwp W

W stands here for writting. I tried lately with tony.wwp that is in the zone.

put tony.wwp in a folder, position on the folder, then type :

wwarp tony.wwp W

It tries to calibrate and fails.

[Toni Wilen]

Much better but wwarp is missing. I am going to be extremely lazy as I more or less promised

The wwarp programme?

[dlfrsilver]

Yes it's this, coded by our friend WEPL its program is very good and helpful ^^.

There Toni: http://www.whdload.de/whdload/WWarp128.lha

The wwarp source is included in the archive

[Toni Wilen]

wwarp tony.wwp W
writing track 0, format dosf
testing drive/dma speed at track 1, $317C.0 $317C.0 $317C.0 $317C.0 $317C.0, 
using writelen $3194.
writing track 1, $3020.0 bytes, success.
writing track 2, $3020.0 bytes, success.
writing track 3, $3020.0 bytes, success.
....
writing track 150, $3020.0 bytes, success.
writing track 151, $3020.0 bytes, success.

and game also works. Where exactly is the problem?

ADDED: after checking my crystal ball: you set "disk length" to bigger than ext adf has space reserved for tracks. You should have explained the situation (much) more clearly...

I've always converted directly wwarp file to extended adf when I needed it.
But Denis likes doing complicated things.

Hi Psygore,
how do you make the conversion?
Did you write a PC/DOS/WIN utility?

I've hacked my amiga program mfm2wwarp. Only to do some quick tests (ie. Ghost Battle).

[dlfrsilver]

OK, let me check

EDIT : Okkk, i wasn't aware of this. At least my question has brought out a solution Thanks toni and Psygore !

[Toni Wilen]

Larger floppy_write_length values should work but you need to create the extended adf after emulation has been started (or you will get standard size ext adf)
