- Added emulation support for the tape drive, and .CAS files loaded into the tape. Raw audio files in the .WAV format are not supported by the emulator directly, but two external programs "wav2cas" and "cas2wav" can convert between them. - Added an additional rendering mode for the X11 video system of Linux machines. Instead of drawing the emulated screen on the display rectangle by rectangle, the "xvideo" mode uses the xv extension of X11 to render into an off-screen memory which is then merged into the screen by the video overlay mechanis of the hardware. This rendering mode may create a smoother display and may improve performance on lower end hardware, but is not necessarily available everywhere. - A complete manual of Os++, including a memory map, is now available as download. - Included the Os++ system disk, including disk-based utilities around Os++ including a Dos overlay manager that relocates Dos buffers behind the cartridge, an RS232 handler, an updated version of DISKIO, a disk-based tape handler, a menu based DUP and a lot of tools.
