  1. Hey, where is this bat file, i saw it on the gta forums but couldnt download it, could someone possibly upload it again or just post the contents of it on this page?

  2. I was just wondering, since you aren’t working on this anymore, if you still have the source code, could you release it? I’d love to see how you do everything, and possibly update it ๐Ÿ™‚ (not release it, unless you allow it).

  3. oh bad to hear that ๐Ÿ™ does this version will do all the job to make my own map total conversion for gta4 ? or it lacks some stuff?

  4. Hey, ben je nog bezig met shaddow mapper v2 ? want ik heb gta eflc ik hoop dat je nog bezig bent zo niet dan heb ik pech ๐Ÿ™ .

  5. This mod is awesome! BUT, I have EFLC (my original GTA disc was lost).

    How can I make this work for EFLC? Your program wants me to select the GTAIV.exe file, but my file is EFLC.exe or something like that…

    In this directory: C:\Program Files (x86)\Rockstar Games\EFLC

    I really want to edit the map! Are you still working on this… or??? You are the only person in the world who has a map editor for GTA IV!


  6. Hey, I saw you quit- well, I guess it’s sad but we all need a break sometimes, eh? Just wondering if you can help me get it running- I’m on windows 7 32Bit. I’ve installed the policy files, got java, read the readme and all that jazz, but it won’t run. I run Startmenu.bat, press ‘4’ for 1024mb mode, select my GTA IV installation that’s not read-only, but all I get is alot of text in the command line window, I think I posted the result in the Shadow Mapper thread. I’m a wee bit unsure how to solve this, and I’d quite like some help on setting it up. But hey man, if you’re busy, don’t worry about it. Thanks in advance,

  7. hey shaddow i know this has probly been asked b4 but i have not yet found the answer or seen a reply. does SM work on windows 7? I can run your program and load the relevant files but once loaded the screen goes dark grey and no images render. Any ideas would be greatfull. also could you provide a link to x86 + x64 please the link on this page is not found. THANK YOU!!!

    What should I do to save the map???
    pls reply
    sorry for my google-english

  10. Ik vindt dat je tot op heden perfect werk heb geleverd better dan ik of iemand anders tot op heden had kunnen doen ( anders hadden ze het wel gedaan )

    vindt het erg jammer dat je dit nu zelf niet meer ondersteund.
    Dat je dit nu dus overlaat aan derden.

    want het nadeel daarvan is dat het nooit jouw flair of kwaliteits eisen krijgt.

    Hoewel SM voor mij redelijk werkt ๐Ÿ˜› is er plaast voor verbetering hoewel ik nog wel eens wil benadrukken dat je echt netjes werk heb geleverd

    ok kan ik goed begrijpen waarom dit alles nu zo gaat

    Je Bouwt iets op met moeite en tijd voooral veel tijd en vervolgens is het voor de mensen nooit goed genoeg.
    praat me er niet van.

    Maar wat ik probeer te zeggen is ga vooral zo door doe wat voor jouw goed voelt laat je vooral niet opnaaien.
    hoop dat er ooit nog een revolutie in shadow mapper komt zoals shadow mapper zelf ooit was

  11. is there any way to working sm at THE BALLAD OF GAY TONY version so i couldnt start the program becuse there is no any GTAIV.exe to select and start the application
    may be you want to know i just installed EFLC pack just contains LOST AND DAMNED and THE BALLAD OF GAY TONY there is no named GTA4.exe to start it any solution pls


  12.

  15. ok vriend ,
    nog 2 twee kleine vraagjes misschien instaleerd ik het mis

    Copy the local_policy.jar and US_export_policy.jar to the โ€œProgram Files\Java\jre6\lib\securityโ€ folder (default)
    —–>moet ik die files vervangen of niet


    Go to your GTA IV folder and make sure โ€œread onlyโ€ is ticked off

    moet de read only geselekteerd zijn of niet????

    antwoord aub

  16. hey vriend ik heb just shadowmapper geinstalleerd en de java extension gekopieerd maar wanneer ik op shadowmapper druk gebeurt er niks
    abtwoord me aub danku
