Altirra 2.7 Test 15 is released. Altirra is an Atari 8 bit Emulator on the Windows/DOS platform. Altirra emulates several models of the 8-bit Atari computers. This includes the the 800, 800XL, and 130XE versions. It has a lot of options, and compatibility is decent especially given the emulator's early stages. It also supports some copy protected games properly in emulation.

Altirra 2.7 Test 15 Changelog:
-Added emulation of floating inputs on PIA port B (XL/XE).
-Added option to disk drives dialog to shift disk images up/down.
-Veronica side now supports expression evaluation and a separate set of loaded symbols.
-Multiple U1MB emulation fixes: removed bogus PORTB dependency for register access, reset flash emulation on cold reset, flash writes to BASIC and OS windows now work (ugh).
-Touch-specific UI fixes: fixed not being able to bring up on-screen keyboard from side panel, fixed multi-touch breakage on OSK and added hit blocking on the sides when it doesn’t fill the window width, fixed not being able to copy text due to the context menu gesture dismissing the text selection.
-Altirra BASIC updated to 1.43. Added several P/M graphics commands from OSS Basic XL: PMGRAPHICS, PMMOVE, PMCLR, PMADR(), MISSILE, and BUMP(). My estimate of 300 bytes for P/M graphics turned out to be way too low — it took ~420 to get to this point, and I still don’t have room for PMCOLOR or PMWIDT
