New Version Of The 8bit Atari Emulator Atari++

This Atari 400, 400XL, 800, 800XL, 130XE and Atari 5200 emulator for Windows moves from the beta to the full 1.55 release now so let’s see what’s been done to it shall we?

Fixed a couple of bugs in the disk emulation, thanks to Konrad Kokoszkiewicz for finding them. Specifically,

Read and write capacity (815 commands) did not check for all supported disk layout types and hard-disk partitions,

Speedy commands were recognized and interfered even if the speedy emulation was turned off

Disk status wasn’t returned correctly for high-density drives

Fixed a parsing/error handling bug if the initial con-figuration files were incorrect.

Fixed the implementation of ZFR1 in the mathpack patch.

Fixed the implementation of FFRAC in mathpack patch.

Added constants required by BASIC for the patch.

This release comes with a new release of Os++, the emulator operating system. For the first time, this release is complete and includes a math-pack whose functions should be both faster and more precise than the original implementation. Thanks to B. Watson for continuously pushing me - it’s done now.

Minor streamlining in the CIO implementation in Os++.

This release adds a STDIO interface to atari++, allowing it to read keyboard or editor input from the command line, and echo-ing output to stdout. This feature can be used for batch-processing.

Compared to the beta release, this version fixes one bug in the BCDToInt math pack routine (also known as FPI) which did not handle carry-over correctly.

Writing 0 to SKCTL now also resets the pokey timers as it emulates the POKEY soft reset.

Pokey STIMER also resets the poly-counters now, as it should.

Os++ includes minor fixes for the cursor rendering and interaction of S: with E:. Writing to S: now shields the cursor correctly.
