A bug in FPGApple MMC was reported by Dirk Verwiebe:
-----------
I made a fresh format and saved one file to the sd card. This was loaded
without problems in the apple/zx core.
Then i saved a second file to the memory card. This file was not loaded
correctly.
But when i saved a third file to the card, selected it in the mmc menu
then the second file was loaded.
Same for 4th and 5th file.Selecting 5th file loads 4th file.
------------
I have just confirmed it with a 512MB card. I was normally using 128MB
SD cards I bought for PseudoDisk use.
Looks like the problem is a bigger cluster size or at lease a different
sector mapping. Should be easy to fix in the "C" code.
The source is on-line. If anyone decides to play with it and fixes it
before I do, please let me know.
