  • ASTROCADE- Fixed some Input menu descriptions and corrected paddles' sensitivities

    • Imgtool Changes
  • Renamed the TI99 module to ti99_old, since the format it handles has been obsoleted by changes in the TI99 driver
  • Added support for Corvus Concept disk images


    • Source Changes
  • The core is based on MAME v0.70. This incorporates all features of the update to this core
  • Modified flopdrv.c to reset pDrive-id_index to zero when head is moved from track to track
  • CRC calculation of read/write images has been disabled (bug #416)
