Be sure to read and follow the procedures carefully and make backups of the affected files as suggested. As many players already know, the game has a bug that does not allow R$$$ sims to work in I-HT (High-Tech Industry). It does create demand for R$$$ (10% of the I-HT jobs) but does not actually employ them. Checking the I-HT buildings (with the Route Query Tool) can verify this. If the city does have neighbour connections, these R$$$ sims might be able to find jobs in other connected cities, otherswise you will get "No-Job" zots at your R$$$ areas. What causes this problem, seems to be the wealth-level breakdown of the I-HT jobs: 10% $, 80% $$ and 10% $$$. The algorithm appears to not work correctly if two of the above percentages are equal. The bug affects all I-HT buildings (Maxis AND custom content), as well as the Medical Clinic, the Solar Power Plant and the Nuclear Power Plant. The fix can be found on the STEX. Click on the link below: - IH missing $$$ jobs fix (update!) 1.11 It works by setting the I-HT jobs as follows: 10% $, 78% $$, 12% $$$, instead of the original 10/80/10 (which caused the problem). It has a small impact on demand (+2% $$$, -2% $$ - of the I-HT jobs only), but this is really unimportant. The problem with this fix (as well as all other mods that modify the RCI-type exemplars) is that it causes another incosistency: some regional statistics (regional jobs, regional residents etc) are double-count. It is unknown what effect this has on total demand, gameplay, city growth etc, and I doubt if anyone has carried-out any testing/evaluation, so it would be best to have this problem sorted-out as well. For some reason, the problem is caused if there are two copies of an RCI-type exemplar in the installation. As with all other exemplars (and other file-types too), the 2nd exemplar will override the 1st one, however some calculations appear to run twice. The solution is simple, have only one occurence of the above exemplar in the installation, and the correct place to put this is of course in its original place, namely simcity_1.dat (a Maxis file, located under the Simcity main installation folder (typically C:\Program Files\Maxis\SimCity 4). Easier said than done, as iLive's Reader (the community's main modding tool) can't modify and save correctly a file as big as simcity_1.dat! (otherwise the fix could be applied in-place). The workaround is to use wouanagaine's SC4 DAT Packer. To apply the fix correctly, follow the steps below. Installation Procedure: - Download and install wouanagaine's SC4 DAT Packer. - Make sure you have the latest SC4/RH or Deluxe versions plus Patches. Right-click on the simcity executable and check the version number. Mine is 1.1.640.0 (SC4+RH+Patches). Refer to other threads to find which is the latest version for your installation. - Backup simcity_1.dat! (Copy this file somewhere else - outside of Simcity's folders, eg under your My Documents folder). - If you are unsure about the SC4 DAT Packer's operation, or you are afraid of possible user errors, better backup your plugins folder too. This may take some minutes if you have a multi-GB installation. Alternatively you can temporarily "move" the Plugin folder contents under another folder - if the folder is in the same drive and volume, moving the files will be virtually instant, as it is technically a "rename" rather than a real "move" operation (no file transfer actually takes place). - Create a new folder under your My Documents/Simcity 4/Plugins folder. - Copy simcity_1.dat under the above folder. - Copy the fix (IH_census_10_78_12.dat) under the above folder and rename it to z_IH_census_10_78_12.dat. This specifies the loading order, and causes the exemplar in the fix to replace the exemplar in simcity_1.dat, as z_... is alphabetically "after" si... - Run SC4 DAT Packer. Initially all folders in the list are selected (highlighted). Find and highlight ONLY the folder you created. This will limit DAT Packer's operation under that folder only. Click on the Start button, wait for the operation to be completed and close SC4 DAT Packer. - DAT Packer should have created a new datfile, containing simcity_1.dat plus the fix. This is located under a folder by default named Plugins_Compressed. Rename this file to simcity_1.dat, and copy it under Simcity's main folder, overwriting the original - you have made a backup, haven't you? - Go back to the Plugins folder and delete the Plugins_Compressed subfolder. Also delete the folder you had created (containing simcity_1.dat and the fix). Alternatively you can move it outside of the Plugins folder and backup it, to remember the operations you performed (for future reference) - you may want to modify it again at some point, eg add more modified RCI exemplars, or "stuff that goes into simcity_1.dat" in general, like some LUA fixes or mods. - If you had (temporarily) moved the Plugins folder contents in step 4, get them back. - You are done!!! Some notes: - It is suggested that you keep the original simcity_1.dat, you may want to apply additional patches in the future. The backup wan't only for safety. - You may want to make similar fixes for the other files affected by the bug, ie the Medical Clinic, the Solar Power Plant and the Nuclear Power Plant. Refer to the modding forums to find how to modify civic buildings correctly. The fixed versions can be inserted in simcity_1.dat as well, or instead placed in a separate plugin (these are normal Building-type exemplars, not RCI ones, so having a 2nd copy will simply override the original, without causing any problem). It is highly suggested that before installing or applying the fix to the above buildings, you enter your cities and bulldoze all instances of them, in all of your cities (save them before exiting). You can replop them after applying/installing the fix. Hope you find this tutorial useful.
