For hard-core Civilization IV enthusiasts that feel the huge maps of the game are too small and Marathon mode is too fast, I made this mod that offers several things:
1. create a huge random map several times bigger then the original Huge map of the game (original Huge have scale factor of 32x20 and TyrMegMa40 Huge is 80x50).
2. game speed, tech discovery, construction and others are a lot slower (about three times slower then original Marathon speed of the game), giving you enough time to play every age a lot.
3. adding on top of it the CvGameCoreDLL.dll that is 40Civs mod, you can fill the world with max 34 starting civilizations and 6 colonies, instead of 18 civs that were allowed in the default game. This make the huge map really lively with a lot of civilizations competing with each other.
4. replaced global warming desert terrain with fallout instead by 40Civs mod.

Start of the mod:
1. - Close Civ4 if is open
2. - Unpack TyrMegMa40.zip to Civ4BtS mods folder:
* for STEAM version of Civ4BtS, Mods folder is: {the place where your STEAM folder is located}\Steam\steamapps\common\Sid Meier's Civilization IV Beyond the Sword\Beyond the Sword\Mods\
* for the standalone installation of the game (if you installed on the default path) Mods folder is: C:\Program Files\Firaxis Games\Civilization4\Beyond the Sword\Mods\
* for Civilization 4 Complete DVD version the Mods folder is: C:\Program Files (x86)\2K Games\Firaxis Games\Sid Meier's Civilization 4 Complete\Beyond the Sword\Mods\
3. - Clear the cache from Civ4 cache folder - just delete all files inside cache folder from c:\Users\{your win user}\AppData\Local\My Games\beyond the sword\cache\
4. - Fire up Civ4BtS and launch the mod from Advanced > Load a mod > TyrMegMa40
The game will restart loading the mod. In upper right corner will be written the name of the mod: TyrMegMa40
5. - At the beginning of the game choose:
* Custom game.
* Map type (Archipelago works best, but other types can be suitable. You can check how a new map is generated by entering the map editor, then restarting a new game with that map type.)
* Size: Huge (This is the one I modified and is about six times bigger then the original huge map of the game. All other sizes are game's default.)
* Speed: Marathon (This is the one I modified. All other speeds are game's default.)
* Deselect Victory: Time victory (To not have the game end just when things start to become interesting.)
* Manually add up to maximum 34 players.
* The other choices are optional.
Required to finish such a game: a strong computer and a TON of patience and free time. Right now this is my favorite way to play Civilization and I like it a lot more then the newer Civ 5 or Civ 6. Enjoy.
Screenshots
1. Game on turn 2167 on year 1931 AD. Notice the size of the game window on the mini-map on the bottom-right corner of the screen. That big the map is.
2. The crowded relations screen.
3. The big planet. This complexity if what makes this mod so wonderful.
Known issues:
1. The map is generated with some lines stretching from some mountains. It doesn't look too bad and it won't affect the game at all.
2. Saves. Sometimes, when loading a save file directly from the game results in a memory allocation failure, then the game must be closed. The good news is that the next time the game is opened, it load the save correctly. A workaround to load a save without problems is to exit to main menu first, unload the mod, then open the desired save file. It will work without issues and is a lot faster.
