Dance Dance Revolution Extreme

This is a decompilation of the System 573/arcade version of Dance Dance Revolution Extreme.

Instructions

Note: YOU MUST PROVIDE YOUR OWN DATA!

Microsoft Visual Studio 2015 x86 Redistributable is required for tools to work properly.

1. Extract the contents of your Dance Dance Revolution Extreme CD to the data_source folder. You should have a DAT folder, GAME.DAT, CARD.DAT, and PSX.EXE file in this folder.
2. Run step1_extract.bat (step1_extract.sh if you are on *nix) to generate the data_raw folder.

(this step needs to be fixed to use the sn toolchain not normal gcc for matching) 3. Under linux compile src/aout you will need gcc-mipsel-linux-gnu.

4. Run step2_make.bat (step2_make.sh if you are on *nix) to build the ddrextrm.iso.

Additionally, if you are building this for MAME, you must use chdman (included with MAME) to build the required CHD.

1. Generate CHD using chdman.exe createcd -i ddrextrm.iso -o c36jaa02.chd -c none (-c none is requested because the compression can throw timing off in MAME).
2. Overwrite roms/ddr5m/c36jaa02.chd in your MAME folder with the newly generated c36jaa02.chd.
3. Delete nvram/ddrextrm in order to force reinstallation when you boot ddrextrm next in MAME.
4. You must run MAME from the command line instead of through the normal MAME UI to bypass hash check errors

If you wish to extract the CD bin/cue from a CHD file, use chdman.exe extractcd -i c36jaa02.chd -o c36jaa02.cue.

Additional Instructions (*NIX ONLY)

If you are building using *nix, you must compile the required Cython modules:

1. cd tools/py
2. python3 -m pip install -r requirements.txt
3. python3 setup.py build_ext --inplace

Notes
