vice3ds

This is a port of the VICE C64 (x64) emulator v3.3 to Nintendo 3DS with a lot of 3DS-specific goodies and added functionality. VICE - the Versatile Commodore Emulator - http://vice-emu.sourceforge.net/

Installation

Install .cia file with FBI - or - copy .3dsx file to /3ds/vice3DS-C64 directory on your SD card and launch in HBL - or - launch .3ds file from flashcard.

Usage

Preconfigured button functions:

Select: open Vice menu

B-Button: Joystick Up
R-button: Autofire. Within vice menu, R-button starts the mapping of a hotkey.
C-Stick: cursor keys
L/ZL-buttons: left/right mouse buttons if mouse is enabled.
3D-slider: Emulation speed (0 = 100%, max = Warp-mode)
Soft buttons functions (from left to right, top to bottom) :
    Autostart image
    Hit RUN/STOP
    Toggle joystick ports
    Toggle C-Pad / D-Pad for joystick
    Warp Mode

    Quickload snapshot
    Quicksave snapshot
    Toggle True Drive Emulation
    Hard Reset
    Pause emulation

    Attach disk image to drive 8

    Type command: LOAD\"$\",8 - LIST

    Hit RUN/STOP
    Hit SPACE
    Hit RETURN

This (and a lot of other things) can be changed in Vice menu. To change the mapping of a soft button (or actually any other button incl. all the 3DS- and soft keyboard buttons) to a menu item in Vice menu, press the R-button when the menu item is selected, then touch/press the button. This button will now be mapped to the selected menu entry.

Vice3DS will run with acceptable framerates (~20 fps with fastSID emulation) on O3DS. However, a N3DS is recommended: Only here, you will get the full 50fps and incredible reSID sound.

Compiling

You need devkitARM (provided by devkitPro) and the following packages: 3ds-zlib, 3ds-curl, 3ds-libpng, 3ds-bzip2 and - optionally - graphicsmagick. Without graphicsmagick, no version numbers will be included in the icon and bottom screen images.

Install these packages with pacman / dkp-pacman:

Windows:

pacman -S make 3ds-zlib 3ds-curl 3ds-libpng 3ds-bzip2

optional:

pacman -S graphicsmagick

Linux:

[sudo] pacman -S 3ds-zlib 3ds-curl 3ds-libpng 3ds-bzip2

optional:

[sudo] apt-get install graphicsmagick

Actually, a modified version of 3ds-curl is required for game downloads to work with the gamebase64 launcher. The 3ds-curl version provided by devkitPro is buggy and @fincs does not want to fix it. Please see devkitPro/pacman-packages#130 for details. Providing instructions for compiling this modified 3ds-curl version, however, would go beyond the scope of this README.

Apart from this, bannertool (https://github.com/Steveice10/bannertool/releases) and makerom (https://github.com/profi200/Project_CTR/releases) should be available in your path.

Clone the repository (including symlinks) and change into the directory:

git clone -c core.symlinks=true https://github.com/badda71/vice3ds
cd vice3ds

If you received any error messages regarding symlinks during cloning, execute copylinks.sh to correct the symlinks

chmod +x copylinks.sh
./copylinks.sh

Finally, start the compile with the command

make
