Dgen

--------------------------------------------------------------------------------
WHAT IS THIS?
--------------------------------------------------------------------------------
This is DGen v1.24, the Sega Genesis MegaDrive emulator running on AmigaOS 4.
The Amiga version was done by Ventzislav Tzvetkov http://hirudov.com

HOW DO I INSTALL IT?
--------------------------------------------------------------------------------

Extract the lha archive to the drawer of your preference. DGen have its own
drawer. DGen supports compressed ROMs through gzip. To be able to use archived
ROMs,
the gzip binary must be present either in C: or in the DGen drawer. Currently
supported are .z, .gz, .f, .z, .lzh and .zip archive formats.


--------------------------------------------------------------------------------
HOW TO USE IT?
--------------------------------------------------------------------------------
The Emulator can be launched from Workbench or from cli. To launch it from
Workbench simply double-click on its icon then select the ROM image from the ASL
requester. Supported are .bin and .smd ROM image formats. Compressed images are
loaded only if the gzip binary is present. If started from cli without any
arguments ASL requester opens for selecting the ROM image. The CLI gives the
possibility to load ROM images directly and other options:

Usage: dgen [options] romname

Where options are:
    -v              Print version number and exit.
    -r RCFILE       Read in the file RCFILE after parsing
                    dgenrc.
    -p CODE,CODE... Takes a comma-delimited list of Game Genie (ABCD-EFGH)
                    or Hex (123456:ABCD) codes to patch the ROM with.
    -P              Use PAL mode (50Hz) instead of normal NTSC (60Hz).
    -d DEMONAME     Record a demo of the game you are playing.
    -D DEMONAME     Play back a previously recorded demo.
    -s SLOT         Load the saved state from the given slot at startup.
    -f              Attempt to run fullscreen.
    -X scale        Scale the screen in the X direction.
    -Y scale        Scale the screen in the Y direction.
    -S scale        Scale the screen by the same amount in both directions.
