| Summary | 0000246: Add support for (most) 7-Zip compression modes |
| Description | Support for most, if not all of the 7-Zip compression modes would be appreciated.
The ones targeted are the .7z compression modes that aren't supported, namely LZMA2 and PPMd. |
| Steps To Reproduce | ... No information required. |
| Additional Information | The real reason for this is, that it would make the use of something like the "Ultra7z (Optimizer)" program much more reliable.
As it tends to use PPMd when it's the best choice, and that (almost) breaks compatibility with Skulltag.
Long story short, it would make the use of Ultra7z very reliable; which would mean that it could be used safely for reducing the size of Skulltag projects/wads/whatever (even further). |

Backported with the latest ZDoom 2.4.1 upgrade. Please check with the newest version to see if it works. |

Using the attached test_compress.pk7 (using PPMd compression in a 7z archive), Zandronum 2.0-131005-1914 errors out with Script error, "test_compress.pk7:decorate.txt" line 1:
Unexpected character:

I've managed to get ultra-compressed LMZA .7z files to work with the latest version...anything besides that will not work. |

Zandronum is using LZMA SDK 4.65, LZMA2 support was added in LZMA SDK 9.04 and PPMd support was added in LZMA SDK 9.11; therefore, upgrading Zandronum's LZMA SDK to 9.20 or any later version should add support for most 7-Zip compression modes.

This is also true for latest versions of ZDoom and GZDoom.

Can anyone check whether the pk7 files that don't work with Zandronum also do not work with GZDoom 880?
EDIT: Attached some test wads. Of these, test-lzma.pk7, test-lzma-ultra.pk7, test-lzma2.pk7 and test-ppmd-ultra.pk7 work with Zandronum 2.0.
EDIT 2: These and only these pk7 also work in GZDoom r880 and WaTaKiD confirms this (also in r900 for what it's worth). We're good here.
