What's new this time? Not much changed in the emulator core, actually. I fixed a couple of quirks of the serial protocol, and native support for CAS files and tape emulation. Prior versions supported CAS files through an implicit conversion to disk boot files, which - obviously - did not work so well if the tape boot tried to play some dirty tricks. Drawback of the native tape support is of course that it takes as long as the original to load... For X11 users, Atari++ provides a new X11 output driver using the Xvideo extension of X11. Depending on your hardware, this may improve the smoothness of the play a lot. Specifically, I would highly recommend this output driver for older systems with intel chipset graphics. Modern chipsets or chipsets with less performing xvideo extension (radeon or nvidia) do not profit very much from this. The biggest advantage of the new release is that it comes with an upgraded and completed Os ROM, Os++, in its latest version. This release adds a complete toolchain for Os++, not only the command line driven DOS from previous versions, but also a user customizable DUP menu, a FMS overlay manager that reduces the memory footprint of the DOS to 256 bytes (yes, really), a customized version of DISKIO - a BASIC extension - a RS232 handler, and a disk-based tape handler adding the missing tape support for Os++. The tape handler also profits from the overlay manager and uses no extra RAM if the overlay manager is active. It also provides a "turbo mode" that improves speed a bit. A full manual of Os++, including a memory map, explaining the FMS, the DOS, the DUP menu, Diskio, the tape handler and the improved mathpack is available for download on the same page as well. As usual, sources for all of that are available on the same page, they are part of the Os++ sources. The Os++ system disk providing the tool chain is available there as well if you want to check how all the magic works. You need ca65 and GNU make to built it. In the next days, I will upload the cas2wav and wav2cas files, a pretty robust and less naive implementation of similar tools you find on the internet. Took some signal processing theory to built them - they emulate the analog circuits in the tape driver and do not follow the naive "hands on" approach taken by many other implementations. Have fun, Thomas
