dcmo5

This is a version of DCMO5 with some changes for an emulation closer to the real hardware.

Uses the MO5 color palette, not the TO7/70 one.

Unfortunately, Daniel decided to develop DCMOTO as a Windows-only and closed source emulator, leaving users of other operating systems without update for a few years. This is an attempt to improve the situation for people not using windows and wanting to run Thomson games anyway.

How to build

This part requires to be used to build C/C++ programs from sources.

Required

A C/C++ toolchain, usually gcc, make and usual build tools on Linux.
CMake
The development libraries for SDL.

Walkthrough

This procedure will create a working directory for CMake to work inside, leaving the minimal amount of CMake artifacts outside of this directory.

The command are given for a typical Linux shell.

Getting the source and preparing folders

Nothing out of the ordinary here. At the end of this sequence, we are into a subfolder build, that was created inside the working copy of the project, and will be the place where CMake generate all its artefacts.

git clone https://github.com/pulkomandy/dcmo5.git
cd dcmo5
mkdir build
cd build

Use CMake to prepare and configure the build process

CMake is invoked a first time to generate the default build AND list any available option.

cmake -LH ..

At the time of writing, the listed options are displayed like this :

// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
CMAKE_BUILD_TYPE:STRING=

// Install path prefix, prepended onto install directories.
CMAKE_INSTALL_PREFIX:PATH=/usr/local

// To enable a print of the scancode on the standard output, usefull when crafting a layout.
DEBUG_SCANCODE:BOOL=OFF

// Path to a library.
SDLMAIN_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libSDLmain.a

// Path to a file.
SDL_INCLUDE_DIR:PATH=/usr/include/SDL

// Where the SDL Library can be found
SDL_LIBRARY:STRING=/usr/lib/x86_64-linux-gnu/libSDLmain.a;/usr/lib/x86_64-linux-gnu/libSDL.so;-lpthread

// To enable a layout crafted for typematrix keyboard with bepo layout.
USE_TYPEMATRIX_BEPO_LAYOUT:BOOL=OFF

If one wants to change an option, one invokes CMake again. E.g., to activate the option DEBUG_SCANCODE :

cmake -LH -DDEBUG_SCANCODE=ON ..

CMake list the options again, if the invocation was correct, the option is changed :

// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
CMAKE_BUILD_TYPE:STRING=

// Install path prefix, prepended onto install directories.
CMAKE_INSTALL_PREFIX:PATH=/usr/local

// To enable a print of the scancode on the standard output, usefull when crafting a layout.
DEBUG_SCANCODE:BOOL=ON

// Path to a library.
SDLMAIN_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libSDLmain.a

// Path to a file.
SDL_INCLUDE_DIR:PATH=/usr/include/SDL

// Where the SDL Library can be found
SDL_LIBRARY:STRING=/usr/lib/x86_64-linux-gnu/libSDLmain.a;/usr/lib/x86_64-linux-gnu/libSDL.so;-lpthread

// To enable a layout crafted for typematrix keyboard with bepo layout.
USE_TYPEMATRIX_BEPO_LAYOUT:BOOL=OFF

Use cmake to perform the build

cmake --build .

If all went well, the program is ready :

Run the project

To be able to load disk images and tape images, copy the software folder into the build :

cp -R ../software .

Run the program and enjoy :

./dcmo5
