This is the 4th pack in series - update/delta version. You should dl it if you already got "hcg pack v2". If not, you should get a full version instead (152gb) There's a cmd file included which will rename existing v2 files to match new torrent. (windows only of course) You can even dl full torrent and point it to a patched v2 folder. Basically, <old v2> + <\_patch\_v2\_to#4.cmd> + <#4 Update> = <#4 Full> Changes since pack #3 (and v2). 0\. As usual - replaced jpgs with lossless (bmp/png). 1\. Fixed company names. 2\. As usual - a lot of romaji fixes. 3\. Removed duplicates. 4\.a. Renamed -\_bmp folder back to ll. 4\.b. Changed lossless format to mixed bmp/png. I use whatever takes less space. 5\. Changed jpg pack method to 7z. 6\. Added AltGetchu and AltEngTitle fields for information.
