Although the initial version of FD disk emulator had
read out data from the SD card by the Nios II processor for each track and developed it to the track image, the Nioss II processor seems to have been
running out due to timeout etc. because it is slow.
For the second version, the Nios II processor reads data from the SD card for each track, but
it has been speeded up by developing it to track image with hardware.
However, it seems that timeout has occurred rarely yet.
Since Nios II seems to have limitations in expanding track-by-track images, in this version,
changed the method of deploying disk images to the whole SDRAM when FD files were selected .
So it will wait for the conversion time when selecting the file,
but it seems that the error has almost disappeared because the load can now operate at the same speed as the actual FDD .
When writing to FD, write back to the SD card at the time of writing is done.
do not unplug the SD card or turn off the power while the emulator BUSY (the rightmost LED) is blinking .
If you switch to another file, you will write back the unsaved image.
At the same time, since the SASI emulator ignored the reset signal, we changed it so that it responds.
For PC88, because the SD card access method is different, the emulator itself is
designed to be compatible, but transplanting is still not done. Moreover, we can not confirm with other than 2HD.
We know that the behavior in single density (FM format) is not accurate.
(Since the track length is doubled, the time it takes for one disk revolution
has been doubled )

May be some one can contact the author and he will start to develop directly on MiSTer?

Are there any Japanese speakers that maybe want to try to figure out how to contact the author and reach out to this person to see if they can convince them of the merits of MiSTer?

As far as i know, the author is a single person, and he can be easily reached on the link posted above. You can write comment in that blog in English. He will reply.
