libretro / same_cdi

SAME_CDI is a libretro core to play CD-i games. This is a fork and modification of the MAME libretro core

SAME_CDI

SAME_CDI is a Single Arcade/Machine Emulator for libretro, forked from MAME libretro, which is a fork of MAME (it's the SAME, get it?), and compiles only the Philips CD-I driver, and then sorts out the claptrap of loading the CD file for emulating. The name removes the name MAME altogether, as thats what I gather the MAME folks want for a fork like this - MAMEs license is below.

GAME FILES

Game files can be either CHD, ISO, or BIN/CUE. Game support/functionality is whatever the MAME version included supports.

BIOS

BIOS file (cdimono1.zip) is required, and can go either in the same directory as your CHD|ISO|CUE files or in the retroarch_system_dir/same_cdi/bios/ directory

Libretro notice

Before sending bug reports to the upstream bug tracker, make sure the bugs are reproducible in the latest standalone release.

To build libretro SAME_CDI core from source you need to use Makefile.libretro make file:

make -f Makefile.libretro

Doesn't play european games

At least not Atlantis - The Last Resort. It doesn't think it's a CDI disc.

MPEG card support: Can we do a crowdfund or could the museum help

So the MPEG decoder hardware in the CD-I is not supported by this emulator, and very understandably so. I would like to offer the resources of the Museum of Art and Digital Entertainment to help make this a roadmap item for Same-CDI somehow. This could take the form of a hack-athon, or dedicated development volunteers giving some time to the project. Or maybe a crowd fund to pay for the work. The CD-I has a lot of games that cannot be loaded due to this limitation, and the Museum is increasingly worried that this work might never happen, and these games would be lost to technical debt.

[email protected] is where you can contact me. I'd love to setup a meeting to discuss the state of this support, find out the requirements for the work, and see what resources the Museum can bring to bear on the project, if appropriate.

Thanks for keeping the project going, and I hope we can find a way to work together on this.
