hi everyone. ive installed RA2 again and still got some of the old maps that i use to play saved onto a old hard drive. the maps are in MPR format. i remember before i only had to copy and paste them into the RA2 folder. now ive gone into Origin Games/ command and conquer/ maps and pasted them there. now when i click on skirmish the maps are not on the list. can i still use the old maps?

Once again Ive dusted down my PC and dug this one out for a playtest. (Well to grab some screenshots). It's one I wrote back in 2003, so Ive not altered anything. You can use a Modded Jungle Jim character in this one. Mission map for anyone running Red Alert2 , you will need the Yuris Revenge mission Disc. The Zip holds the all01umd.map file and the ra2.csf string file. Place these two files in the Westwood Red Alert2 folder. Then launch the game and select the Allied Mission. There is also a read me file and mini map included in the zip. Once your finished playing this mission simply remove both these files and the Red Alert Game will be restored. Editor: FinalAlert2 Created:11th April, 2003 Name: Jungle Fortress Size: 100x90 Players: 1 Theatre: New Urban To play this mission:Yuris Revenge mission disc required. Extract the contents of the winzip file into your Red Alert2 Directory.Launch the game,select new campaign for the Allies. The game will then launch.                      "You want a War?-----You got it!"                      --------------------------------------------------------------------------- Info: Once again were calling Tanya into the theatre of war. This time it's a rescue mission, and Tanya is going to be executing it! We have received a radio transmission from deep within the jungles of Africa. The transmission informed us of a secret Soviet base operating deep within  the Jungle. Further more the source of this communication appears to be a small group of Russian Scientists who have been imprisoned within the walls of the base. Here they have been forced to work-on and develop a new Soviet defence system. The system from what we can understand is stealth based.  This fact coupled with the location of the enemy base makes detection virtually impossible. However these three Russian Scientists have now expressed a wish to leave their Soviet masters, and have asked for our help in extracting them. The nature of these Scientists work makes them important assets to the allied war effort against hostile forces. We cannot allow the Soviets to develop this "Stealth technology", and must therefore recover the scientists and destroy the base. This will effectively deprive the Soviets of an important breakthrough and deprive them of its source. Tanya is on route, prepared as ever for battle, she will assist you in infiltrating the base, recovering the three Scientists and escorting them back to the Landing Zone. Once there we will send in a nighthawk to remove the Scientists from the combat zone, while sending in a MCV and reinforcements to aid you in the destruction of the Jungle Fortress!  Objective 1: Destroy the forward Radar Array.  Objective 2: Locate and Evacuate the defecting Soviet Scientists.  Objective 3: Destroy the Jungle Fortress.  Objective 4: Keep Tanya alive. Hints:Read on, Do not read these unless you are really stuck. 1>Send Tanya to the Radar array, destroying this causes two Tesla coils to powerdown. This is the entry point into the Soviet base for Tanya, all she has to do is time her moves correctly to avoid those patrolling telsa tanks! 2>Once inside the base its of paramount importance that Tanya keeps a low profile. Destroying any structures can lead to immediate retaliation! 3>Head to the East then North, in the general direction of the Soviet Scientists. 4>Once again plan your moves with care, the Soviets will send conscripts and Flak troops at you but that should be all. 5>Destroy the allied power-plant close to the Soviet Oil derricks, (North East corner),  this controls the power to the Yuri Statue. Failure to do so will result in  Tanya's demise. 6>Once rescued keep your Scientists together. Lead them back Keep them in a group of three as they approach the Nighthawk landing pad. 7>There are plenty of cash crates hidden in the game, beneath destroyed Tanks, Ruins, Flak cannons ect. 8>There is also a nuke crate hidden somewhere in the game. 9>My advice is to prepare for  any air attack, the AI loves building Kirov's, but resorts to tesla tanks and Appoc's when it feels the need. 10>Beware the Chimps in Hard mode! 11>The Special "Jungle Jim" unit is trainable, but takes plenty of action to achieve, however once he's fully Elite, he is a force on his own! But he's not invincible!     Ok so there u have it, A RA2md.CFS file has been added. This will overwrite any other RA2mdCSF.file which you may of installed in your  RA2 Folder from previous downloaded missions.The file contains text which been altered in order to fit  with the maps theme! Explanation: The ALL01umd.map file when placed in your RA2 folder preceeds the standard Yuris Revenge game disc missions. This means that the first mission played when the game is launched will be this mission. To restore your games original first mission simply remove the all01umd.map file from your RA2 folder. The RA2md.csf file contains the text for this mission, it also preceeds your game disc csf file. As above once you have finished playing this mission remove the RA2mdcsf.file. This also causes your game to revert to reading from the mission  disc as opposed to reading data from the RA2 folder. Various slight moddifications have been added, all to keep in with this missions theme. The moddifications will not alter your  original RA2 game.
