Do you have problem with some particular games/disk? While the most delicate components of the amiga (after the disk drive) are the cia chips who manage external peripherals (like joysticks, mouse, serial port,parallel port, and disk drive), if your floppy drives works good, the interface should do the same. So for instance a long game name like "Fiendish Freddy's Big Top 'O' Fun Disk 1' fits without problems.ĭuring the development I tested with more than 3500 games without issues. Anyway it should not be a limit in a normal usage (I mean if you don't put others info on the filename like year released, company etc.). so it really depends on the text, if text size is too long it will be crunched preserving the head and the tail (it usually contains the disk number).
You have done a great job with this, now all we need to do is use the Pi to become an Amiga HardDrive unit :o) Rispondi Eliminaįor the menu the file name length it's not fixed because the font is proportional. do you know if the external drive can have more power than the internal one?

More disks/External Drive - I found that with games like Indiana Jones/Flight of the Amazon Queen/Monkey Island, the Games have 11 disks and you can only apply 4 disks per drive? You mentioned that when used internally you can only use 2 of the 4 drives is there a way round this? Do you have info on how to make the device external? I know with Kickstart rom 2 and above its possible to set the Amiga to boot from external drives first meaning you could have the device using all 4 drives. I have been using ADF files (as most of what I downloaded is adf as standard) Reliability - I'm not sure if my Amiga is just a bit more flakey due to its age, or maybe if its drive timings but it seemed to crash a fair bit. I have found a few minor issue though:įile name length - it seems that theres a limit to the filename length for the menu I wondered if you knew how long this might be? Really good work on this, I copied how you instructed and built an interface, which after several weekends of soldering works (with a model B Pi on external power for the interface).

If you have a lot of disks to rip, I suggest to put the SD in a PC and make all the adf files named as you like (you just make an empty file copy it and rename it), so in start up program instead to choose "Empty Disk" you can choose the right one. if the name is "illegal" because no standard AmigaDOS disk, you have to quickformat the "Empty Disk" giving it the right nameĦ- in copy select "DOSCOPY+", X-Copy will start copying the floppy contentħ- push "Write to SD" button so save all the work The Adf file we are going to make will have this name. These are in detail the steps you need to follow:ġ- disable the second drive on interface using dip-switchģ- in the setup you put in first virtual drive X-copy and as much "Empty Disk" as you need, the original floppy in the external disk driveĤ- start the program and, when you are in X-Copy click the "change disk button", it will remove the X-Copy disk and put the "Empty Disk" in the first driveĥ- select "NAME" to see the name of the original disk.

You can get the content of floppies with the software X-Copy you find in the software package (see above the software section, there is a video too).
To know more about MFM coding anyway and other useful stuff here there are lot of infos.
So if between 2 zeros there are 4 us, the system recognizes a '10' sequence (the line is inverted), if there are 6 us the system recognizes a '100' sequence and if there are 8 us the system recognize '1000', as it's the MFM coding. The approach in this case was to take the times between the 0 cells (on the falling edge) and use these to obtain the data stream. For the data in input, the DKWD line, indeed it was not possible to use SDI because without a clock or a PLL, errors will appear soon. In order to have a better shape for the DKRD line, the signal should stay low for less than 2 us (400ns should be good) so the signal was 'reshaped' by the resistor R15, the capacitor C3 and the diode D6, improving the compatibility with the Amiga software (really only few games are sensible to this timing).

In order to manage the DKRD line (disk read) and have a full stream of data with exact timing (2us per cell) sent without any interruptions,holes or delays, the software uses the SPI interface in continuous mode: all the MFM data goes through the SDO pin while other SPI pins are not used and they are configured and treated as standard GPIO.
