* Base64A clone with 48Kb of base RAM and paged ROM

Storage
* 16 Sector 5 1/4 diskettes. Uncompressed or compressed witth gzip or zip. Supported formats:
  - NIB (read only)
  - DSK
  - PO
  - WOZ 1.0 or 2.0 (read only)
* 3.5 disks in PO or 2MG format
* Hard disk in HDV or 2MG format with ProDOS and SmartPort support

Emulated extension cards
* DiskII controller (state machine based for WOZ files)
* 16Kb Language Card
* 256Kb Saturn RAM
* Parallel Printer Interface card
* 1Mb Memory Expansion Card (slinky)
* RAMWorks style expansion Card (up to 16MB additional) (Apple //e only)
* ThunderClock Plus real time clock
* Apple //e 80 columns card with 64Kb extra RAM and optional RGB modes
* No Slot Clock based on the DS1216
* Videx Videoterm 80 column card with the Videx Soft Video Switch (Apple ][+ only)
* SwyftCard (Apple //e only)

Useful cards not emulating a real card
* Bootable SmartPort / ProDOS card with the following smartport devices:
  - Block device (hard disks)
  - Fujinet network device (supports only http(s) with GET and JSON)
  - Fujinet clock (not in Fujinet upstream)
* VidHd, limited to the ROM signature and SHR as used by Total Replay, only for //e models with 128Kb
* FASTChip, limited to what Total Replay needs to set and clear fast mode
* Mouse Card, emulates the entry points, not the softswitches.
* Host console card. Maps the host STDIN and STDOUT to PR# and IN#
* ROMXe, limited to font switching

Graphic modes
* Text 40 columns
* Text 80 columns (Apple //e and Videx VideoTerm)
* Low-Resolution graphics
* Double-Width Low-Resolution graphics (Apple //e only)
* High-Resolution graphics
* Double-Width High-Resolution graphics (Apple //e only)
* Super High Resolution (VidHD only)
* Mixed mode
* RGB card text 40 columns with 16 colors for foreground and background (mixable)
* RGB card mode 11, mono 560x192
* RGB card mode 12, ntsc 160*192
* RGB card mode 13, ntsc 140*192 (regular DHGR)
* RGB card mode 14, mix of modes 11 and 13 on the fly

Displays
* Green monochrome monitor with half width pixel support
* NTSC Color TV (extracting the phase from the mono signal)
* RGB for Super High Resolution and RGB card
* ANSI Console, avoiding the SDL2 dependency
* Debug mode: shows four panels with actual screen, page1, page2 and extra info dependant of the video mode

Tracing capabilities
* CPU execution disassembled
* Softswitch reads and writes
* ProDOS MLI calls
* Apple Pascal BIOS calls
* SmartPort commands
* BBC MOS calls when using Applecorn

Other features
* Sound
* Joystick support. Up to two joysticks or four paddles
* Mouse support. No mouse capture needed
* Adjustable speed
* Fast disk mode to set max speed while using the disks
* Single file executable with embedded ROMs and DOS 3.3
* Pause (thanks a2geek)
* Passes the A2AUDIT 1.06 tests as II+, //e, and //e Enhanced.
* Partial pass ot the ProcessorTests for 6502 and 65c02. Failing test 6502/v1/20_55_13; flags N anv V issues with ADC; and missing some undocumented 6502 opcodes.
