          CIV1_PLAY_1TO1 - Play against just 1 computer Civ... Or even 0! - patch002_play_1on1.xml - source: http://forums.civfanatics.com/showthread.php?t=499613
          • This patch adds the possibility to select "2 Civilizations" or "1 Civilizations" to the number of Civ selection screen, and then starts the Civ game with the corresponding number of Civs: if 2 is selected, the player is playing against a single computer opponent; if 1 is selected, the player is playing alone!

          CIV1_PLAY_FOREVER - Play never-ending games! - patch003_endless_game.xml - source: http://forums.civfanatics.com/showthread.php?t=499911
          • This patch removes the "retirement" limitation that ends games on year 2100 (Chieftain) to 2020 (Emperor). It does NOT remove other endgame conditions such as conquest (all opponents destroyed) or space conquest (spaceship reaches Alpha Centauri)

          CIV1_EARTH_RAND_START - Play on earth with random starting positions - patch004_random_EARTH_startpos.xml - source: http://forums.civfanatics.com/showthread.php?t=499611
          • This patch bypasses the hard-coded starting positions when playing on Earth, and makes Civ choose random positions instead. This can be especially useful when playing with a custom-designed MAP.PIC

          CIV1_STARVE_INC_POP - Food-starving cities have their population... increase! - patch005_starve_incs_pop.xml - source: http://forums.civfanatics.com/showthread.php?t=497438

          • After applying this patch, the high-level path-finding data for land movement (also present in SVE files) will be generated properly by CIV; the actual impact on CIV games is unknown

          CIV1_F10_LOAD_GAME - Rewires F10 shortcut key to load saved game from within CIV - patch008_F10_load.xml - source: http://forums.civfanatics.com/showthread.php?p=12766006#post12766006
          • After applying this patch, pressing F10 key will open the "Load Saved Game" screen and allow the player to directly load a previously saved game; the World Map can still be shown by using the menu item from the WORLD menu; note: some side effects have been noticed, this functionality is not guaranteed

          CIV1_RERESPAWN - Opponent Civs can now respawn more than once - patch011_rerespawn.xml - source: http://forums.civfanatics.com/showthread.php?t=514562
          • The original CIV code only allows a Civ to be respawned once after it is destroyed (not including the special case of SCHISM); this patch removes this limit by skipping the verification that the Civ is being re-spawned for the 2nd time; Note: discrepancies in the Replay are to be expected

        • Open PIC image files, export them as GIFs, edit their color palettes on the fly
        • Convert custom image files to PIC images, import native PIC's palette and overwrite or remap your custom's image colors
        • And with all the above mod you CivDOS PICs at will
      • Font editor
        • Open CivDOS native fonts, export them as GIFs, import modified or original fonts and convert them back to CivDOS-compliant FONTS.CV

    • Java 7 must be installed on your system; note: later versions of Java may be supported as well, but are untested
    • Successfully tested on Windows XP, Windows 7 and Linux (Ubuntu); assumed to work on all OS's with Java 7 support
    • To enable edition of savegames, an original copy of Sid Meier's Civiliation for MS-DOS must be installed on your system; supported versions are listed below (other versions may be supported too, but are untested):
      • English 474.01
      • English 474.03 (not fully tested)
      • English 474.04 (not fully tested)
      • English 474.05
      • English 475.01
      • French 474.05

    How to install and use:

    • Unzip the package file JCivED-0.0.18a.zip on your disk
    • Double-click jcived.bat (Windows) or jcived.jar to launch JCivED
    • For legacy reasons, PIC conversion functions are available from the command line, by running piced_cmd.bat (Windows only), with the following parameters:
      Spoiler :

              piced_cmd x -pic <source> -gif <target> [ -pal <palette> ]
                      Extracts a PIC-compatible image file, converting it to a 256-color
                      GIF image file:
                       -pic <source>  specifies the input PIC-compatible file
                       -gif <target>  specifies the target GIF file
                       -pal <palette> an optional palette file
                      If no palette is specified, the program will attempt to use the palette
                      included in the input file <source>. If <source> does not contain a
                      palette information, then a default palette is used.
                      If the file <palette> contains valid palette information, it supersedes
                      any palette information contained in the <source> file. Otherwise the
                      program proceeds as if no palette was specified.

    Wow. Just wow. Very, very, very nice work.

    To try things out I ran the Gamesave Editor, built some terrain, gave London population 20 and all city improvements, and changed militia stats to 10/10/10. It all worked. Opens up endless possibilities...

    I'm just impressed at the effort you made to do this. Really, really, really nice work. !

    Thanks a lot jarvisc, as always :)

    Actually, they are far from being fully tested from every angle, so bugs are to be expected... Also, as I tried to highlight with the "alpha" mention everywhere, those are really work-in-progress versions, meant to be fixed and enhanced. I really just did this release because I felt I had stable versions in my hands that could be released for everyone to enjoy.

    I didn't take the time to make proper roadmaps, but among the various things I intend to enhance are:
    • PIC Editor:
      • functionality to convert arbitrary images (GIF, JPG, ...) into PICs to enable graphical modding of Civ; I have been thinking about this form the first release of CIVED, but it is far from straightforward, because of the way Palettes are designed and used in Civ
    • GameSave Editor:
      • Fully decipher the SVE contents and enable its editing in the tool, including: map visibility, wonders, governments, history replay, score graph, city resource usage, etc.
      • Improve UI to edit units/cities from the Map view
      • Obviously, enable terrain improvement edition (road/mining/pollution/...)
      • Add special resource and tribe huts (not deciphered yet)
      • Different edition modes, e.g. hacker, where any value can be put anywhere for experimenting with Civ behaviour with invalid data, and safe where the tool enforces game rules (prevent units from different Civs on the same square, cities on the ocean, etc.)
      • Support more versions of Civ, for both savegames and UI graphics, including (if possible) savegames coming from WinCiv and other Civ I ports; and to a further extent, the possibility to convert gamesaves between Civ versions (long road ahead...)
      • Support more platforms, probably meaning to develop adapted UIs (Java Applets for the web, J2ME for mobile devices, etc.)
      • Provide a proper API to manipulate gamesaves (can't do this until I decipher the SVE fully)
      • ...

    In a word, I have great ambitions - and consequently there is a great risk that most of the above will never be achieved :)
    Although feedback like yours, jarvisc, is really a good motivator to continue the work!

    Anyway, thanks again, and I'll keep you posted with any progress.

    Hey darkpanda. That sounds very ambitious!

    I was just using your tool to help me experiment with the so-called One City Challenge. I made a random map, then came into JCivED Gamesave Editor to remove almost all the land such that every civ starts on its own continent only big enough for one full city. I've got more ideas after that, too.

    In short, having a blast!


    PS good luck deciphering all that save data format. I like how for now, you just exposed all the "unknown data" arrays to look at in the data editor.

    very good! I like the simple interface!
    I'll look into it more hopefully soon when I have more time.
    keep up the good work!

    What's up with the palette anyway? I expected to see 256 VGA colors but obviously not. It also looks like there's room for 280 colors in the palettes; I'm assuming this is just due to representation and not capacity.

    You're right, it is due to representation, not capacity: actual palettes can only have up to 256 colors, and accordingly each pixel of a PIC image is just a single byte, which value ranges from 0 to 255, representing an index in the 256-color palette.

    It is not straightforward because different types of PICs are actually using only limited ranges from the color-palette: in the screenshot from PIC editor (see first post), you can see all the magenta color in the palette which is actually unused.
    I am assuming this makes it possible to combine multiple PICs within the screen at the same time, without all the PIC's palettes colliding with each other; e.g. GOVT*.PIC (members of government) + BACK*.PIC (diplomacy background, depends on type of government) + KING*.PIC (leader graphics) would have non-colliding palettes to when combining them to display a diplomacy screen.
    So whenever someone wants to customize those graphics, care should be taken with the palette.
    This is just an assumption, though, and I didn't explore all the details yet so I may be mistaken.

    Another problem is: how to create the palette of an arbitrary, imported image (PNG, GIF, JPG) ? generate it automatically ? "cast" the image onto an existing PIC Palette ? allow the user to manually create his own palette ?
    Probably, all of the above would be nice, but then it takes time to design and implement, and I would rather code 1 function properly than 3 or 4 half-baked buggy algorithms... So, time will tell which way I will go first!

    Thanks for the heads-up anyway!

    I just added support to change tax rate and science rate in my latest dev version of GameSave Editor, and tried to put some impossible values:


    Civ seems to have accepted them,as you can see in the screenshot (in French, sorry) but I wonder what the actual effect could be :)

    I've been enthusiastic about your work as it promises great prospects, so I made all you spoke about - installed Java7, then downloaded and launched JCivEd0.0.1a. For the first time I chose the save of this scenario http://forums.civfanatics.com/showthread.php?t=276242.
    I tried to change population of Venice - entered 9 instead of 8; it didn't work. Then I tried to reassign Venice from the German civ to the Chinese (represent Hungary); to do this I changed owning civ number from 3 (Germany's one) to 5 (Chinese); it gave nothing. Each time I switch on another item (a city or a civ) old data are being restored.
    How to make it work?

    Hi fluyt!

    Thanks a lot for you enthusiasm and your bug report.

    As a matter of fact, I downloaded the custom save game you linked above, but failed to open with JCivED GameSave Editor, getting an "Invalid format exception" ... I think the MAP format, being custom and non-standard, cannot be opened succesfully (I should look into that, by the way...)

    So I loaded it in Civ and then re-saved it, so Civ would generate the format supported by JCivED: this worked.

    Now, I identified your issue: if you input a value in a field and then click in another field without pressing Enter, your change will be lost. But if you press Enter before leaving the field, your change is saved.

    I have done the changes you mentioned and it worked fine, as you can see below (I moved the submarine as well so I could discover Venice, invisible by default):


    By the way, any such change you perform in the Data tab is immediately visible on the Map tab, so it is a good way to confirm whether your changes are taken into account:


    To conclude: I know this bug sucks, and I had already fixed it before you mentioned it, in the current DEV version, so that if you just click outside the field (loses focus), then the change is saved. But I don't plan to patch the existing release yet, as there is a workaround for it, unless you convince me that your life is impossible without it :)

    A new, better release will come within weeks anyway :)

    Thanks again, and good luck!

    Oh thanks! It changed a lot - I have been bearing a plan of creating a scenario for CivI and now it's become possible!

    Well, forgive me if it's off-topic, but I think this is a great Civ red deserving attention and available tools in my humble opinion are sufficient to do one's own toil.
    First of all I started a customized game (with little land), waited a turn, saved and cleaned the map up. I got two saves - one with reserved ice caps and the second without.
    View attachment blank map with ice caps.rar
    View attachment blank map w-o ice caps.rar

    Tomorrow I'm planning to find a suitable physical map, define the exact borders of the region and correlate the scale of the implemented region with the Civ's 80x50 map.

    Hi everyone,

    Finally I could code an Image-to-PIC function in JCivED PICED that seems to do the job, I am so excited that I can't resist sharing a screenshot of this achievement:


    The actual PIC editor release that makes this possible will come in a few days, after I make sure there aren't (too many) loose ends crippling the thing.

    I am also attaching the actual KING04.PIC created this way, for anyone who wants to try it out (sorry for the ZIP format, this forum doesn't seem to allow PIC files):

    View attachment KING04.zip

    For the record, the original GIF still has to be properly engineered, in order to match the original PIC's size (320x200) and contain fewer than 256 colors (this is actually not mandatory because the palette casting discards the original colors).

    It's been and still is a hardnut as I've never been making a single map or scenario, so it's going to take a while.

    First of all, I was in search of a suitable map so it could be set to the Civ map with ease. My original idea - a map of Baltic - I had to throw off because I didn't see an optimal way to cut edges, so I delayed it until better times and switched on West Europe; I have a clear idea concerning what to do, but I won't reveal the historical epoque for the time being.

    I resorted to the method described here: http://forums.civfanatics.com/showthread.php?t=29350. I was making a list of over 40 cities writing down their x's and y's of .gif (finding absent cities in google/wiki) and divided them on the number to correlate them with Civ coordinates. Then I mapped cities by 1-tile spots of grassland and disposed settlers there.


    To have possibility of editing map (i.e. improving land and building roads) I placed one settler of every nation to prevent the auto victory by conquest or any bug, while Egyptians were assigned a human player ID as well as all anew created settlers. So after having built all world cities I would be able to improve terrain peacefully; also I can create endless number of settlers without need to assign them to certain cities, so the process will take not much time.

    Would you prefer to be able to edit improvements through JCivED ?

    If so, I can focus on that functionality and try to release it ASAP. Should be quite straightforward.
