Jens Schoenfeld says that a new CF adapter went into production, that clears the removeable-bit of all CF-cards, without the need of a software tool or PC.
If he's got the source code for the Buddha's driver (which I guess is in flash on the card as it is bootable), it should be trivial to make the changes to support these removable CF cards. Seems to me either pure laziness, they have lost/forgotten how to change the buddha driver, it is impossible to update the ROM on the buddha.
I favour the laziness option. It is cheaper and less time consuming to do nothing. Shame they do not open-source under GPL such things so there is a chance an Amiga coder could fix it.
