Floppy emulator (user interface)
Floppy emulator (user interface)

Description: Emulator allows to choose an ADF image from the flash media (SD/MMC card), then loads it into memory (legacy 4MB SIMM), converts it into MFM tracks and deliver these to Amiga's floppy bus. Amiga senses it as drive DF1:. I was able to perform DISKCOPY from DF1: to DF0: which gave me perfect Amiga floppy :-)

Sorry, haven't seen your reply in my mailbox. Could you please resend it again?

And what is that IPF format?

UPDATE. Silly me, should've checked all private messages first :-)

...as I also emailed to you: reading IPF images could resurrect hundreds of deceased games... :)

Definitely. I thought of hacking a simple utility to convert 512-byted sectors from .ADF into some form of .MFM file on PC. Resulting file would be 1.8Megs, or roughly twice as big as .ADF. Shouldn't be a problem since MMC storage is quite cheap these days.

Now it takes MCU good 1m45s to convert ADF into MFM, and 1.8M should load in less then one minute.

wow, a perfect replacement for DF0:

would it be faster if the floppy images were stored in some other format than adf so that you don't need that conversion?

Right away :-)

WOW ! Now that's what I call an alternative to WHDLoad ! Can you post details ? It really deserves an article on it's own !!
