1. Go to where you installed Gunz. (default is C:\ijji\Gunz\English\)
2. Find the file system.mrs
3. Download the mrs decompiler from here:
   1. Gunz MRS Decompiler
4. Under Decompile/Unpack, type in system (without the .mrs)
5. A folder called system should appear
6. Open up the folder system and there should be abuse.txt and many .xml files.
7. Follow Alexis Septimus's tutorial
   1. Original: Guide And Tutorial In Editing System.mrs
   2. But many people are lazy so:

      Merged: Here's Alexis Septimus' tutorial. Are you new in editing system.mrs ? Don't know how to edit it ? Here is a tutorial on how you can edit system.mrs without having any trouble at all. 1) abuse.txt You must be wandering how the heck should you edit abuse.txt, did't you ? Well, abuse.txt is part of the system.mrs that are implement by ijji to prevent users from using vulgar language. You can remove the filter by using the example below. Code:

   Quote:

   Before Edit 2,b@stard END After Edit END Once you set it out this way. Whenever you chat with a person at gunz, you can use the word which had been filter by ijji. From this example shown, you can't used the word b@stard. But, after you remove it from the abuse.txt. You can use it whenever you want. Do not remove the word END, if you remove it. You system.mrs might crash and not working. 2) AnimationEvent.xml I recommend you not to touch this part cause this part had been done nicely by ijji. 3) channelrule.xml You must be wondering what the heck is channelrule is all about. To make it simple for you, channelrule is to enable you to create certain map which are prohibited for certain channel. For example, channelrule enable you to create Stairway map while you are inside Expert Channel, Beginner Channel, Free Channel and etc etc channel that unable to create this map. How to enable it ? Here is a example shown below Code: Prohibited Map (Before Enable) <!-- <MAP name="Stairway" /> --> Prohibited Map (After Enable) <MAP name="Stairway" /> Once you do so, the stairway would be available for the channel. However, I can't guarantee this might work or not cause ijji might had patch this part and make it to server-sided instead of client-sided. 4) chatcmds.xml I recommend you not to touch this part cause this part had been done nicely by ijji. 5) cserror.xml You might be asking me what is this cserror.xml all about. Won't you ? At here, you can edit all those command that would appear at gunz whenever you did something such as selling/buying item or get disconnect from server and etc etc. Here is a example of how you can edit it. Code: Before Edit <STR id="30003">You cannot enter at your current level.</STR> After Edit <STR id="30003">Are you stupid ? You cannot enter at your current level.</STR> 6) droptable.xml Don't bother to edit this part cause ijji had already make [COLOR=orange! important][COLOR=orange! important]it [COLOR=orange! important]server[/color][/color]-sided.[/color] 7) filelist.xml This is the most important part of all the entire system.mrs, it is also the part where you are require to edit it if you want to develop a auto-quest map or wall hack map such as Virus Zero System. You need to ensure the crc32 number of the auto-quest map are match with the crc32 number at your filelist.xml or else you would get Can't Create Game Error whenever you try to play Quest mode. Example are show below. Code: Auto-Quest map CRC32 number is 2864d73a Before Edit <FILE NAME="quest/maps/Dungeon_cavern1/Dungeon_cavern1.RS" CRC32="a72808fc"/> After Edit <FILE NAME="quest/maps/Dungeon_cavern1/Dungeon_cavern1.RS" CRC32="2864d73a"/> Please do remember that all the crc32 number in this filelist.xml must match with the entire crc32 number of xml available inside the system or else your system would crash. 8) gametypecfg.xml This is the section all system editor edit their system.mrs to enable megastage. However, due to ijji fix this section. I don't think it is necessary to explain about this section anymore. 9) LenzFlare.xml I recommend you not to touch this part cause this part had been done nicely by ijji. 10) locale.xml There is nothing to be edit in this section 11) messages.xml This section similiar to cserror.xml, below are the example Code: Before Edit Vote is rejected After Edit Your vote had been throw into dustbin 12) notify.xml There is nothing to be edit in this section 13) npc.xml Don't bother to edit this part cause ijji had already make it server-sided. 14) questmap.xml Don't bother to edit this part cause it is server-sided. 15) scenario.xml Don't bother to edit this part cause it is server-sided. 16) strings.xml You must be asking me what is strings.xml is all about ? Won't you ? Well, all I can said is this section is for those item description and you can edit those weapon and armor description at here. There is 4 way to change the title and description. However, I would just mention 1 way cause this is simple and yet faster for me. Below are the example being shown Code: Before Edit <STR id="ZITEM_NAME_1">Rusty Dagger</STR> <STR id="ZITEM_DESC_1">It has some rust here and there. Once used, it's sure to be difficult to sell.</STR> After Edit <STR id="ZITEM_NAME_1">Dark-Sun Martial Dagger</STR> <STR id="ZITEM_DESC_1">An obscure dagger handed down from the Moon dynasty.</STR> 17) system.xml I recommend you not to touch this part cause this part had been done nicely by ijji. 18) tips.xml You ask me what is tips ? Well, tips is something you give waiter after he serve you. Just kidding dude, well tips.xml is used to edit those message that appear in gunz loading screen whenever you start a game or join a game in a lobby. Below are example of how you should edit it. Code: Before Edit <MSG>If you have any inquiries about GunZ, you may use the Helpdesk function on the GunZ Main Page.</MSG> After Edit <MSG>Auto-Quest Map by lalalakid</MSG> 19) worlditem.xml You might be asking me, what is worlditem.xml is all about. Well, worlditem.xml is for you to set the time interval or should I said respawn rate of item that could recover your hp/ap/ammo and how effective it is when it comes to recovery. If you set the time shorter, it would respawn faster while if you set the time longer. The item would take longer time to respawn. If you set the amount higher, the more it would recover you while the lesser you set the amount, the less efficient it would be. Here is a example show below. Code: Before Edit <WORLDITEM id="01" name="hp01"> <TYPE>hp</TYPE> <TIME>3000</TIME> <AMOUNT>10</AMOUNT> <MODELNAME>red</MODELNAME> After Edit <WORLDITEM id="01" name="hp01"> <TYPE>hp</TYPE> <TIME>500</TIME> <AMOUNT>50</AMOUNT> <MODELNAME>red</MODELNAME> Please be wary not to set it too high or too low cause it might cause your system.mrs to crash. 20) zitem.xml Ok, this is the part where most of the work are and perhaps the part which is the most headache for those beginner who want to develop their own system.mrs with premium/quest/unreleased item mesh_name mesh name is to edit some clothes or weapon to other type of look. For example, dagger01 is the code for Rusty Dagger while dagger02 is the code for Phantom Slaying Dagger mesh_name="dagger01" mesh_name="dagger02" Once you edit it to dagger02, Rusty Dagger no longer look like Rusty Dagger. But, it would look like Phantom Slaying Dagger. res_sex This is to enable whether a men character or women character able to use this equipment or not. I recommend you not to mess with it. res_level No point in edit this part although you make the level requirement lower, the level requirement are still normal cause it is server-sided. weight Server-sided, no use in edit it bt_price Server-sided, no use in edit it Delay When you reduce the delay, your weapon could attack faster while increase the delay would make it attack slower. It work perfectly while in quest mode when you are solo. While you are playing with other player, your attack speed are still normal to them although you attack them faster. Thus, there is no point in editing this section cause it would just waste ammo cause your firing speed is faster. However, there is some information that said it work perfectly well with melee weapon cause it enable them to slash/stab faster at gladiator mode while some claim it work well with range weapon if you did't reduce the delay too much. But, don't ask me, I not sure regarding about this matter. delay="366" delay="316" damage Ok, this is the part where a lot of system editor make error regarding about it. If you are making a auto-quest system.mrs, then it is good if you increase the weapon damage. But, it ain't good if your system.mrs is for other mode. You must be asking me, why should we reduce the damage instead of increasing it ? Won't it be much better ? Ok, here is my explaination. This is because system.mrs are client-sided and everybody had their own system.mrs. If you increase the damage of your system.mrs, you would eventually receive more damage shall your opponent hit you with weapon that you had edit the damage inside the current system.mrs you are using by increasing it. However, if you reduce the weapon damage. You would receive lesser damage depends on how much you edit in your system.mrs. You might ask me, if I reduce my weapon damage in my system.mrs. Won't I deal lesser damage to him ? No, you won't deal lesser damage to him. As I said before, this system.mrs are client-sided and everybody had their own system.mrs. Thus, they would receive the damage from your weapon according to their own system.mrs Another possible question you might ask me is why should I increase the weapon damage if I want to develop auto-quest system. This is because monster at quest mode are client-sided to your system.mrs, they ain't another player who had their own system.mrs. Thus, they would receive the edited damage from your system.mrs However, if you edit the weapon damage for NPC (Monster) to lesser. You would receive lesser damage from them while increase it would make their attack stronger. This is where most system editor edit to make it unnecessary for a player to switch on god mode using other type of hack whenever they auto-quest. range What is range ? Ok, edit the range of the weapon would be fun. Ever wonder to see a dagger able to stab a enemy from extremely far distance ? Wow, this is far better compare to Houdini magic trick. But, be wary this only work for quest mode. If you increase the range of the weapon to be able to slash/stab or shoot further, it won't do you any good in any other mode other then quest mode. ctrl_ability Control ability is to prevent your weapon from spraying. Set it to "O" to make the weapon had 100% accurancy. If you set it to "100", your weapon would completely spray out. magazine magazine ? Book for you to read perhaps ? Nope, if you edit this section to had more ammo. You would had more ammunition, but those ammunition might not fully function at all except at quest mode when you are questing alone. reloadtime Edit the reload time would enable you to reload faster, but it might not work. hp if you add number into it, let's said from "O" to "25", the item would add your life by 25. But, if you set it from "O" to "-25". It would deduct your life instead of increase your life. So, remember not to add a dash on it if you don't want this to happen. Please don't add to much such as 9999 cause ijji had set the limit. It would just make your system crash ap Same like hp maxwt Don't need to edit, server-sided. maxbullet Same like magazine limitspeed Setting the limitspeed to 100 would enable you to walk in normal speed while setting it to below 100 would cause your movement speed decrease. This is where VirusZero and me set the speed to 0 to develop anchor lock for our auto-quest system. If you ask me, if set to more then 100. I don't know, but probably would make your system.mrs crash. limitwall Set it to "1" would prevent the user of the system.mrs from making thing such as wall running while setting it to "0" would enable them to wall running. This is where all those system editor edit to make the user of their system capable to wall run with rocket launcher and machine gun. 21) zquestitem.xml I recommend you not to touch this part cause this part had been done nicely by ijji. 22) zskill.xml Ok, we are down to the final section of editing system.mrs Here is where you edit the system.mrs to prevent the monster from casting spell to you. However, I lazy want to explain all of it. Just give this small detail to you all. mod.damage Set it to 0 to prevent the monster spell from damaging you while adding it would increase the damage. delay Set it as high as possible, so that the monster only able to cast the spell only once if they really do cast it. knockback Sometimes when the monster cast a spell at you, you would bounce to somewhere else. Did't you ? Set it to 0 to prevent such a thing happen. That's all I had to said, there is actually more function available to be explain. But, I am too lazy to write more then that. In the meantime, enjoy editing system.mrs Remember to thanks me if this guide/tutorial help you in editing system.mrs

8. If you want to add premium clothes, follow x1nixmzeng's guide.

      Shared by donzqwijn Normally, you copy the clothes you want to add, and paste over the original item, leaving two of the same items with seperate ID's. Now, you have to swap them over. I'll warn you now, it takes twice as long (if not longer) to get the same sort of system as back in December. All these edits are done in zitem.xml, and remember to hash this file to 7B2C02BC. Example 1 - Replacing Ares Iron Gloves with PA Gloves (MALE) Ares Iron Gloves now using PA Gloves mesh Code: Code: <ITEM id="522020" name="STR:ZITEM_NAME_522020" mesh_name="eq_hands_15" totalpoint="0" type="equip" res_sex="m" res_level="15" slot="hands" weight="3" bt_price="500000" ="1" ap="13" maxwt="0" sf="0" fr="0" cr="0" pr="0" lr="0" color="#FFFFFFFF" desc="STR:ZITEM_DESC_522020" /> PA Gloves now using Ares Iron Gloves mesh Code: Code: <ITEM id="22003" name="STR:ZITEM_NAME_22003" mesh_name="eq_hands_34" totalpoint="0" type="equip" res_sex="m" res_level="20" slot="hands" weight="8" bt_price="1000" hp="0" ap="15" maxwt="0" sf="0" fr="0" cr="0" pr="0" lr="0" ="#FFFFFFFF" desc="STR:ZITEM_DESC_22003" /> Quick Editing Tips <LI _Knee="1" xTdBw="0">Locate items in strings.xml. You can search for item id's you found here. Use Gunz Entropy (not clams system, the program). You can see which items have been edited and check if you've got something wrong without starting Gunz. Thank the mrs editors! This new technique takes a lot more effort! Lastly This is discussion - do not post your files here, be very specific with what you have problems with. This technique applies to weapon and clothing meshes. We are unable to edit some stats.

9. Take note of the xml files which you have edited.
10. After you have edited the xml files you want, open up filelist.xml.
11. Download BruteCRC from here:
    1. [release][tool]BruteCRC
    2. Tutorial on how to use BruteCRC:
       1. Start BruteCRC tool and press Select.
       2. Pick 1 of the file(s) you edited.
       3. Look at the filelist.xml for the crc hash of the file you edited, paste it in the request crc32[hex] field and press Do it.
       4. Wait for a while. Depending on the file size, the amount of time needed differs.
       5. A popup will appear, with something like Append bytes to file? Press Yes.
       6. Repeat steps 2 - 5 for every file you edited.
    3. If you don't understand my instructions, you might want to take a look at x1nixmzeng's tutorial with screenshots.
       1. Post-MRS Editing Tutorial [PICS]
12. Use the MRS Decompiler tool (link provided above) and compile the system back.
    1. Under Compile/Pack, key in the folder name where all the .xml files reside in (default is system).
    2. Click Compile.
    3. A system.mrs file has appeared.
13. Congrats, you have created your own system, instead of leeching from other people!

Notes:

• Please read and follow instructions carefully and no errors will occur.
• BruteCRC may look like it is crashing when you click Request. Just wait and it will not crash.

Editing Notes:

• Editing weapon damages will get you kicked out of room immediately.
• Editing weapon delays will get you kicked out of room immediately.
• MAIET updated something so quest NPCs' melee will hit you even if you set mod.damage to 0. To overcome that:
  1. Open zitem.xml in Notepad.
  2. Press Ctrl - F to find a phrase.
  3. Type in NPC.
  4. Once you have found the phrase NPC, look below it.
  5. Delete everything within the arrows (the arrows are below the phrase NPC).
  6. Resistance to melee attacks are working now xD

Please, I made this tutorial because I don't like the Gunz Hacks/Bots Discussion section to be flooded with "Help" titles.

Sv3nt3k or lalalakid, if you find this useful, you might want to stick this?
Thanks.
