Amiga Gurstnibbler for PC

DOS, BAM, DEEP...

Supported Controllers:
Greaseweazle, ADF-Drive, DrawBridge aka Arduino Amiga Floppy Disk Reader/Writer

Update: 01.04.2026
Ver. 0.1

Hello Amiga friends...
A new copy program is ready for testing.

Many...many thanks to Martin Zimmer for his great program on the Amiga

GURSTNIBBLER

Working functions are:

Greaseweazle and ADF-Drive:
DOS -> ADF file>floppy disk and floppy disk>ADF file,
BAM -> ADF file>floppy disk and floppy disk>ADF file (only data from bitmap; much faster),
DEEP -> SCP file>Diskette and floppy disk>SCP file (incl. copy protection),
- Sorry but writing SCP to Disk is not supported by ADF-Drive,
DMS2Disk -> DMS file>floppy disk,
DMS2ADF -> DMS file>ADF file
IPF2Disk -> IPF file>floppy disk,
QFRMT -> quick formatting the disk writing X-Copy-Bootblock and a bitmap,
ERASE -> erasing the disk,
Selection of the floppy disk drive:
- IBM A or B
- Shugart 0 or 1 or 2
Copy IPF-file -> floppy disk...
- SORRY but writing SCP to Disk is NOT SUPPORTED by ADF-Drive Controller
Until now you can copy whole disks.
If you use beginning-end (say track 10-20), only the data of these tracks will be copied. (file will be smaller than 880 kb).

You can write to multiple destinations

DrawBridge aka Arduino Amiga Floppy Disk Reader/Writer:
Detecting DrawBridge works...
Erasing disk works...
Reading/writing up to come...

Left click on PC-VERSION by Arne Urbaniak plays and stops music

Note:
So far, copying with 2 Graeseweazle devices only works when both have twisted cables and the drive selection is set to IBMPC: A !
I don't know why yet.
I'm working on it.

Happy copying...

I would be glad about feedbacks and improvement suggestions from you.
Sometimes i can't see the forest for the trees.
