Altirra 2.7 Test 21

Altirra 2.7 Test 21 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 21 Changelog:
features added:
UI: Raised drag-and-drop limit to 128MB to accommodate The!Cart images.

bugs fixed:
AltirraOS: CIO PUT RECORD with length=0 now outputs A without EOL.
Debugger: Fixed .readmem command.
PCLink: Fixed FLEN (code 4) command.
Recorder: Video recording failed if scanlines were enabled without VBXE or antialiasing on.
U1MB: Internal BASIC now works with 1200XL + U1MB, since the U1MB emulates the XL/XE MMU.
UI: Selecting a 1200XL kernel no longer switches the hardware mode to 800XL.

POKEY: Fix regression where having the serial port in external clocking mode with no external clock blocked the serial polling bit.

AltirraOS: Fixed Mad Pascal plot incompatibility due to undocumented PUT RECORD with len=0.
Debugger: Fixed .readmem command.
