CeDImu

Experimental Philips CD-I emulator (I use a capital I instead of a lower case i because the Green Book capitalizes it)

Note: the project is still in a very early development stage, please open issues only to address problems in the existing code.

How to use

See the user manual.

Compatibility

DVC support will be added when CeDImu will have a good compatibility with the base case system on several boards.

BIOSes

Below are listed the known BIOSes that works in CeDImu along with their board settings. For more information, see the ICDIA website.

• CDI 210/40 (Mono-3, 8 KB NVRAM)
• CDI 220/60 (Mono-3, 32 KB NVRAM)
• CDI 220/80 (Mono-4, 32 KB NVRAM)
• CDI 470/00 (Mono-4, 8 KB NVRAM)
• CDI 470/20 (Mono-4, 8 KB NVRAM)
• CDI 490/00 (Mono-4, 32 KB NVRAM)

Some BIOSes (e.g. CDI 220/80) may not show graphics on their first boot. To boot them, let them run for around a thousand frames on the first boot so they initializes their NVRAM, then reload the emulator.

Boards

Compatible means it is capable of playing discs.

• Mini-MMC

  ​ Not working. SCC66470 and Timekeeper mapped.

• Mono-3, Mono-4

  BIOS boots to player shell. MCD212, Timekeeper (8KB and 32KB) and HLE IKAT mapped.

  • Debug (memory access logs and exception and system call tracing)
  • RAM Search
  • Memory Viewer
  • Savestates

How to build

Build macros

ENABLE_LOG: if defined, allows the library to print some messages in the console and the use of OnLogMemoryAccess callback (default: OFF).

The official build of CeDImu always enables it.

CMake

Variables

LIBRARY_TYPE: used to build the core as a static or shared library (default: STATIC).

BUILD_CDITOOL: build cditool or not (default: OFF).

Windows

Use CMake-GUI

Linux

Package dependency: libwxgtk3.0-gtk3-dev

Install the dependency, then open a terminal in the root directory of the git and type:

mkdir build
cd build
cmake ..
make -j$(nproc --all)

If you want to have the memory access logs, replace cmake .. with cmake .. -DENABLE_LOG=1

libCeDImu

If I get everything listed upper working, stable and fully functional, the goal is to create libCeDImu, a complete library (static and/or dynamic) to allow any program to implement CDI applications (other emulators like Bizhawk, MAME, etc).
