VICE, the Versatile Commodore Emulator

Background

VICE is a program that runs on a Unix, MS-DOS, Win32, OS/2, BeOS, QNX 4.x, QNX 6.x, Amiga, Syllable or Mac OS X machine and executes programs intended for the old 8-bit computers. The current version emulates the C64, the C64DTV, the C128, the VIC20, practically all PET models, the PLUS4 and the CBM-II (aka C610/C510). An extra emulator is provided for C64 expanded with the CMD SuperCPU.

M3U and Disk control

When you have a multi disk game, you can use a M3U playlist file to be able to change disks via RetroArch Disc Control interface.

A M3U file is a simple text file with one disk per line (Wikipedia).

Example:

Ultima VI - The False Prophet (1990)(Origin Systems).m3u

Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 1 of 3 Side A)(Game).d64
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 1 of 3 Side B)(Surface).d64
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 2 of 3 Side A)(Dungeon).d64
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 2 of 3 Side B)(Populace A).d64
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 3 of 3 Side A)(Populace B).d64
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 3 of 3 Side B)(Populace C).d64

Path can be absolute or relative to the location of the M3U file.

When the game asks for it, you can change the current disk in the RetroArch "Disc Control" menu:

  • Eject the current disk with "Eject Disc"
  • Select the right disk index with "Current Disc Index"
  • Insert the new disk with "Insert Disc"

By default, RetroArch will display the filename (without extension) of each M3U entry when selecting a disk via the Current Disc Index drop-down menu. Custom display labels may be set for each disk using the syntax: DISK_FILE|DISK_LABEL. For example, the following M3U file:

Ultima VI - The False Prophet (1990)(Origin Systems).m3u

Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 1 of 3 Side A)(Game).d64|Game
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 1 of 3 Side B)(Surface).d64|Surface
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 2 of 3 Side A)(Dungeon).d64|Dungeon
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 2 of 3 Side B)(Populace A).d64|Populace A
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 3 of 3 Side A)(Populace B).d64|Populace B
Ultima VI - The False Prophet (1990)(Origin Systems)(Disk 3 of 3 Side B)(Populace C).d64|Populace C

...will be shown in RetroArch's disk selection menu as:

1: Game
2: Surface
3: Dungeon
4: Populace A
5: Populace B
6: Populace C

If DISK_LABEL is intentionally left blank (i.e. DISK_FILE|) then only the disk index will be displayed.

For games that require a dedicated save disk, one may be generated automatically by entering the following line in an M3U file: #SAVEDISK:VolumeName. VolumeName is optional and may be omitted. For example, this will create a blank, unlabelled disk image at disk index 5:

Elite (1985)(Firebird Software).m3u

Elite (1985)(Firebird Software).d64
#SAVEDISK:

Although one save disk is normally sufficient, an arbitrary number of #SAVEDISK:VolumeName lines may be included. Save disks are located in the frontend's save directory, with the following name: [M3U_FILE_NAME].save[DISK_INDEX].d64.

Save disks generated by the #SAVEDISK: keyword are automatically assigned the label: Save Disk [SAVE_DISK_INDEX].

Extra M3U features

  • #COMMAND:<commands>
    • Pass arguments to VICE (place first, core name can be skipped)
  • #SAVEDISK:<label>
    • Create a save disk in saves
  • #LABEL:<label>
    • Alternative label for the next entry
  • <disk>.d64:<prg>
    • Load a program instead of "*"
  • <disk>.d64|<label>
    • Set a friendly name (shown in "Disc Control")
  • <disks>.zip#<disk>.d64
    • Specify a disk inside a ZIP with multiple disks (not needed with single file ZIPs)

M3U playlist supports disks, tapes, cartridges and programs.

ZIP support

ZIPs are extracted to a temporary directory in saves, bypassing the default frontend extraction.
The temporary directory is emptied but not removed on exit. ZIP is not repacked, which means saves and highscores are lost.

This allows:

  • Automatic M3U playlist generation of all files
  • The use of zipped images in M3Us

Virtual keyboard

The VICE cores have a virtual keyboard that can be accessed by default through RetroPad Select.

The virtual keyboard can be controlled with:

  • RetroPad

    Button Action
    D-Pad Move
    B Keypress
    A Toggle transparency
    Y Toggle ShiftLock
    Y (Long) Quick map button
    Y (Very long) Quick clear button
    X Press Space
    Start Press Return

  • Keyboard

    Key Action
    Cursors Move
    Enter Keypress
    CapsLock Toggle ShiftLock

  • Mouse

  • Touch screen

The virtual keyboard has these additional actions:

  • ShiftLock off:
    • STBR = Toggle statusbar
    • JOYP = Switch joystick ports
    • TRBF = Toggle turbo fire

  • ShiftLock on:

    • SVDS = Create/Insert & remove save disk
    • ASPR = Toggle aspect ratio
    • CROP = Toggle crop mode

  • Reset (Red key with undo icon, obeys 'Reset Type' core option)

  • Datasette controls (Reset, Play, Rewind, Forward, Stop)

Long press for sticky keys. Stickying the third key will replace the second.

Joyport control

Older C64 games tend to use joystick port 1 and newer ones tend to use port 2 for player 1. There are several ways to switch ports in this core:

  • Use the core option: Quick Menu -> Options -> RetroPad Port
  • Bring up the virtual keyboard with Select button, and press the key labeled JOY
  • Press the default keyboard shortcut Right Control
  • Assign Switch Joyport to any RetroPad button under Quick Menu -> Options
  • Rename the game, eg. Bruce_Lee_j1.tap or Bruce_Lee_(j1).tap for port 1, and similarly Bruce_Lee_j2.tap or Bruce_Lee_(j2).tap for port 2
  • Add -j1 or -j2 parameters in custom command line .cmd
