This is "DroidArcadia", a port of a subset of the AmiArcadia/WinArcadia
29.37 emulator to the Android platform. The following machines are
emulated:

    * the Emerson Arcadia 2001 console family (Bandai, Emerson,
      Grandstand, Intervision, Leisure-Vision, Leonardo, MPT-03, Ormatu,
      Palladium, Poppy, Robdajet, Tele-Fever, Tempest, Tryom, Tunix,
      etc.) (c. 1982);
    * the Interton VC 4000 console family (Acetronic, Cabel, Fountain,
      Hanimex, Interton, Prinztronic, Radofin, Rowtron, Soundic, Voltmace,
      Waddingtons, etc.) (c. 1978); and
    * the Elektor TV Games Computer (1979).

Features include: artefacting, autofire, force feedback, frame skipping,
game help, gamepad support, high score management, horizon dejittering,
saved states, sprite demultiplexing, tone retuning, trainers.

Instructions
------------

Input from a peripheral will be shown as yellow on the keypad and paddle
gadgets. Other input will be shown as white. Red and blue represent the
left and right players, respectively. A button in green is autofiring.
Games which only use one button will automatically use the "one-button
mode", in which the twelve small keypad buttons are replaced by one large
button.
  Real (host) gamepads/joysticks/keyboards are mapped as follows (an
8BitDo Zero 2 gamepad is shown here):

      L                   R
  
      +                   X
      |    
    +-+-+               Y   A
      |
      +   SELECT  START   B
      
Y:      1st firebutton
X:      2nd firebutton
B:      3rd firebutton
A:      4th firebutton
L:      B/LC
R:      Toggle autofire on/off
START:  START
SELECT: A/UC
D-pad:  paddle directions

For Arcadia and Interton, the on-screen RESET button is the same as the
"Reset" command in the options. For Elektor, the on-screen RESET button
is an ordinary console button; the "Reset" command in the options will
still reset the machine as normal.
  BIN files (raw dumps) can be loaded for Arcadia and Interton. TVC and
PGM files can be loaded for Elektor; however, PGM files must be renamed to
have a .pro extension instead of .pgm (eg. Foo.pgm -> Foo.pro ). Saved
states (COS files) are also supported, via the "Quickload state" and
"Quicksave state" commands in the options. DroidArcadia COS files are not
currently compatible with Ami/WinArcadia COS files.
  "Stretch to fit: 4:3 NTSC" is the same as "Off" except that in NTSC mode
the screen will be stretched slightly vertically to have the correct 4:3
ratio (similar to the "Stretch NTSC" option of WinArcadia).
  See the Ami/WinArcadia user manual for documentation about any features
that are shared with those emulators. The licence is also the same as for
those emulators.
  The emulator was written in C and Java, using Android Studio 2022.1.1
aka Electric Eel. It was tested on a ZTE Optus P500 at 480*960 resolution
(176 dpi) with Android 9, and on BlueStacks 5.11.1.1002 P64.
