Overview

This is my Vita and Switch port of Enigma, a skill/puzzle game inspired by Oxyd on the Atari ST and Rock'n'Roll on the Amiga.

The object of the game is to uncover pairs of identically colored Oxyd stones. Simple? Yes. Easy? Certainly not! Hidden traps, vast mazes, laser beams, and, most of all, countless hairy puzzles usually block your direct way to the Oxyd stones … If you are new to Enigma, you may want to take a look at a few screenshots or peek at the user manual.

Thanks

Thanks to my supporters on Patreon: Andyways, Count Duckula, Jesse Harlin, Thomas Luten, Matthew Machnee, Mored4u, Ibrahim Fazel Poor, RadicalR.

Thanks to @usineur for his libkbd-vita code for easy use of touch keyboard text entry.

Thanks to the developers of VitaSDK and other developers on the Vita for making this possible, in no particular order: @devnoname120, @TheOfficialFlow, @yifanlu, @Rinnegatamante, @cpasjuste, @xyzz, @xerpi, and many others.

Thanks to the many developers of the original game, such as the main developers Thomas Bernhardt, Raoul Bourquin, Siegfried Fennig, Martin Hawlisch, Daniel Heck, Ronald Lamprecht, Andreas Lochmann, Petr Machata, Nobby, Nat Pryce, Jacob Scott, Sven Siggelkow, Ralf Westram, and many many others.

Special thanks to Meinolf Schneider / Amekudzi for the original Oxyd games on Atari ST and PC which inspired Enigma.

Installation Instructions

Vita:

• Install the .vpk
• Extract the contents of data.zip into ux0:data/

NOTE: I recommend using FTP transfer to copy the files over (~10,000 small files in data.zip). There is one report (thanks @ji11x38) that using the Vitashell "SELECT Button: USB" option to copy files directly from a MacOS computer to the Vita via USB caused the files to not transfer correctly, causing Enigma to crash on startup.

Switch:

• Extract the contents of Enigma_Switch.zip into the switch folder on your SD card, so that you have a folder switch/enigma with enigma.nro and more folders and files inside.

Vita/Switch-exclusive features

• game controller support: analog joystick mouse controls and button mappings
• front and rear touch controls with left/right mouse click gestures
• complete level packages with >3,000 levels and pre-calculated preview screenshots
• Bluetooth/USB keyboard and mouse support. The Vita supports only a limited number of BT devices, tested working with Jelly Bean BT keyboard and mouse combo ASIN:B06Y56BBYP and with the standalone Jelly Comb Bluetooth Wireless Mouse ASIN:B075HBDWCF. The Switch supports only a limited number of USB mice. Tested working with Logitech M187.

Controls (controls updated with version 1.08)

Left analog stick = analog control of the marble and mouse pointer
Square / Y / L-trigger = select menu items, use object in game (left mouse button)
Triangle / X / R-trigger = cycle through inventory items (right mouse button)
Cross / A = ok in menu (return)
Circle / B = back / in-game menu (escape key)
Start / Plus = help screen (F1)
Select / Minus = destroy marble and remove one life (F3)
R-trigger + Select / R-trigger + Minus = restart level (shift-F3)

Dpad in menu = quick-select menu items (arrow keys)
Dpad left/right in game = quick-change mouse speed
Dpad up/down in game = cycle through previous messages

Front touch = analog control of the marble and mouse pointer
Rear touch = analog control of the marble and mouse pointer (Vita only)
Single finger tap = select menu items, use object in game (left mouse button)
Dual finger tap = cycle through inventory items (right mouse button)

Dual finger tap works by holding one finger down and quickly tapping with a second finger somewhere else.

Mouse sensitivity can be adjusted in options or in-game via dpad left/right. The setting affects analog joystick, touch, and real bluetooth/USB mice.

Build Instructions

Vita: On Vita, Enigma needs xerces-c and inet. To prepare compilation:

• with a text-editor, load the file $VITASDK/arm-vita-eabi/include/netinet/in.h. Inside the file, replace "struct" with "inline struct" on line 45 and 49.
• download or clone my xerces-c repo from here into a folder called xerces, then:

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=$VITASDK/share/vita.toolchain.cmake -Dmutex-manager=nothreads -Dnetwork=OFF -DCMAKE_BUILD_TYPE=Release -Dsse2=OFF -Dthreads=OFF -DBUILD_SHARED_LIBS=OFF ../xerces/

make -j10
make install -j10

You should now have the file

$VITASDK/arm-vita-eabi/lib/libxerces-c.a 

and a whole bunch of header files in

$VITASDK/arm-vita-eabi/include/xercesc/

• Clone the Enigma repo into a folder called Enigma and compile:

mkdir build
cd build
cmake ../Enigma/ -DBUILD_PSP2=ON -DCMAKE_BUILD_TYPE=Release
make enigma.vpk -j10

Switch: On Switch, Enigma needs ssl and xerces-c. To prepare compilation:

• download or clone the moonlight-switch repo which contains libopenssl here, then:

cd moonlight-switch/dependencies/switch-openssl
export MOONLIGHT_DEPDIR=$DEVKITPRO/portlibs/switch
dkp-makepkg
sudo -E dkp-pacman -U switch-openssl-1.0.2o-1-any.pkg.tar.xz

• download or clone my xerces-c Switch branch from here into a folder called xerces (use git checkout switch to make sure you are on the switch branch), then:

cmake -DCMAKE_TOOLCHAIN_FILE=../xerces-c-1/switch.toolchain.cmake -Dtranscoder=iconv -Dmutex-manager=nothreads -Dnetwork=OFF -Dsse2=OFF -Dthreads=OFF -DBUILD_SHARED_LIBS=OFF -Dxmlch-type=uint16_t -DULONG_MAX=4294967295 ../xerces-c-1/
cmake -DCMAKE_TOOLCHAIN_FILE=../xerces-c-1/switch.toolchain.cmake -Dtranscoder=iconv -Dmutex-manager=nothreads -Dnetwork=OFF -Dsse2=OFF -Dthreads=OFF -DBUILD_SHARED_LIBS=OFF -Dxmlch-type=uint16_t -DULONG_MAX=4294967295 ../xerces-c-1/
cmake -DCMAKE_TOOLCHAIN_FILE=../xerces-c-1/switch.toolchain.cmake -Dtranscoder=iconv -Dmutex-manager=nothreads -Dnetwork=OFF -Dsse2=OFF -Dthreads=OFF -DBUILD_SHARED_LIBS=OFF -Dxmlch-type=uint16_t -DULONG_MAX=4294967295 ../xerces-c-1/

make -j10
sudo -E make install

• (I don't know why repeated cmake is neccessary, but it only works that way for me)
• Clone the Enigma repo into a folder called Enigma and compile:

mkdir build
cd build
cmake ../Enigma/ -DBUILD_NX=ON -DCMAKE_BUILD_TYPE=Release
make enigma_switch.zip -j10
