About

A recompilation of Dodonpachi Saidaioujou using rexglue, working from the Xbox 360 release. It requires your own Xbox 360 dump of the game plus the Title Update 1.01 file.

How it differs from the original

Slowdown is heavily tweaked compared with the Xbox 360, tuned to mostly match shmupmame 5.3.1 for expert and regular modes; Xbox Arrange mode has no slowdown tuning. Optional input-lag and render patches cut input lag from 3 frames to 1.

Getting started

For the disc release, put the SDOJ iso and the Title Update file beside the executable and run launch.bat or launch.sh; for the Games on Demand release, use a converted GoD iso plus three patch files extracted from the matching title update. Press F4 in game for settings; keyboard input is enabled with mnk_mode in the Input tab.

Known issues & limitations

Slowdown is tuned mostly to match shmupmame 5.3.1 in expert and regular modes; Xbox Arrange mode has no slowdown and will not be tuned for it.
The render patch can sometimes cause graphical artifacts.
Frame delivery is currently poor, and the game may not look smooth unless run through Special K.
Audio fadeout issues can occur when not using Special K.
The render patch sometimes introduces graphical artifacts, frame delivery is not smooth, and there are audio fadeout issues unless Special K is used.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Xbox 360 version).

You need your own DoDonPachi Saidaioujou Xbox 360 dump.

Features

You can turn the input and render patches on or off through launch arguments.

How to install

For the disc release, place the SDOJ ISO and TU1 file beside the recomp executable, then run `launch.bat` or `launch.sh`.
For the Games on Demand release, place a converted GoD ISO beside the executable, extract the three listed files from the matching TU file into that folder, then run `launch.bat` or `launch.sh`.
The first launch extracts the ISO if needed and installs the three TU1 patch files; after setup, you can remove the ISO and TU container.

Controls

Press F4 in game to open settings.
To enable keyboard input, turn on `mnk_mode` in the Input tab.
