    There was a bug when starting mmixvd. It would comlain about a registry entry beeing too big. You can savely ignore this error. It happens when a certain key is not found in the registry. This bug is fixed in Version 1.6 Revision 1.44 as of Jan 30, 2015.

  • Version 1.6

    There was a bug when loading and/or storing, BYTE, WYDE, and TETRA values: The allignment restrictions (rounding off to a multiple of two (WYDE) or a multiple of four (TETRA)) were ignored. When loading a signed BYTE, WYDE, or TETRA, there was no sign extension. These problems are fixed in version 1.8.
