Rocks 2 Rockets is a mod-mod of Caveman 2 Cosmos. It has been trimmed down with the aim of getting it playable through the end of the game on a significantly less capable system than is required by C2C. It is still a large mod, just less demanding than C2C. There have been some adjustments for balance purposes. There have also been a few modifications for other reasons, and perhaps a bug fix or two that is not yet in C2C. The entire "galactic" era has been cut out, as has much of the "transhuman" era. Less drastic cuts have been made across the earlier eras. Features supplied by the game engine as of C2C version 26 are all present, including the viewport functionality, as well as many later bug fixes, AI improvements, and optimizations. R2R has a topic in the mod-mods subforum of the Caveman 2 Cosmos forum at the Civilization Fanatics' Center.
This is patch version 0.2 for Rocks 2 Rockets version 0 or 0.1. It is only a patch, you must have the full version 0 of Rocks 2 Rockets installed for it to be of any use. You do not need to have patch v0.1 installed as this patch also includes everything that was in that one, but it will install fine if you do.
Instructions: (Revised due to error in the folder name in the 7-zip file.)
It will replace 22 files outside the Sources folder, listed in the "Files in this patch" section in the Patch v0.2 Notes.txt file which is included in the download, and all .cpp and .h files in the Sources folder (132 .h files and 137 .cpp files; not all of these were changed but I did not feel like sorting them - about 59 out of the 269 have modifications), and add 2 new files consisting of the patch notes and the new scenario, plus 4 XML files from patch v0.1.
Once it is installed, the information you see by moving your mouse over your civilization's flag in game will report the Rocks 2 Rockets DLL as version 2 and any game saved with it will, when loaded, show the Save File versions as version 2. If you don't see this, then it has not been installed properly.
You can continue playing existing saves. If you do, it will probably pop up a dialog box immediately after you get to the game map asking if you want to do a "modifier recalculation". This is part of a cross-version compatibility feature added to Civ4 by the C2C mod team allowing you to keep playing the same save with a new version of the mod. In this case you can skip the modifier recalculation with no significant issues since very little relevant to that has changed. Only the Carnival and Radio Telescope building adjustments should be relevant to what it is recalculating. If you do the recalculation and it crashes, start again and skip it. Whether you do the recalculation or not, the next time you save the game the save file will include the new version number, and such, and after that it won't ask if you want to recalculate when you load the save.
This patch includes a new CvGameCoreDLL file which includes several bug fixes,
several optimizations, and a few new features which are not currently used. The
new optimizations should decrease the time it takes the game to process turns
for the AIs by at least 10%, probably a bit over 15%, from what it took with v0.
This patch also includes a scenario which is functional. None of the ones included in the original v0 release worked as they were all unmodified for use with C2C.
This patch introduces one which does now work with R2R:
R2R Earth - 28 Civs 124X68.CivBeyondSwordWBSave
As the name of the file suggests, this is a 124 by 68 Earth map which starts with 28 civilizations. This is larger than a standard sized Large map, but smaller than a Huge map. It has been adjusted a bit to better match the contents of R2R.
