I didn't realize this until now but the archive of the site with the 1.2 maps for Gold doesn't have them in that particular revision of the page, seams they removed it later. Go to revision Dec 18, 2007 to find it.

I figured out what the Radeon patch is. Here's a video of an ATI card without the patch for those who are curious:
Unfortunately nobody seams to remember who created it. I also found out that EOP's full name was Eater of Pies and his res fix was once called Mech3Loader.

GuyFawkes 2019-05-08 1 point

I did a analysis of the no-cd here with HxD and it appears to incorporate EOP res fix. I'm curious where the Radeon fix comes from. Anyways I've found an official Map Pack (or so it claims, not sure if it was really endorsed or not so more analysis may be needed) here:
The problem is it does a checksum on the exe file to determine the version of the game you have installed (requires 1.2) and it doesn't like the no-cd exe.
Also, doing some digging, I found that 1.2 added 2 new maps to the game but the devs forgot about them in Gold/deluxe version (whatever the version that included Pirate's Moon with the base game was called). An unofficial patch to add the missing maps is available here:
Not really needed for these rips sure, but someone might be grateful to find it.

I have a guide on how to run Mechwarrior 3 and Mechwarrior 3: Pirate's Moon on modern PC's that you can find here:

I've gotten both running excellently on modern Win10 machines. If you need any help, there's contact info in the guide. As well, you can help contribute to the project by making pull requests or issues to improve the guide.

Happy hunting!

What is the difference between the RIP and ISO and how do I install these games on Windows 10?

One of the greatness games in the history of mankind. The all time most requested game of all time on and probably on other game download sites. For a very good reason.

Hi, I tried to put the patch in but it says insert cd, i put the patch installer into the c folder, that did not change the response.

The no cd patch just wont start, i moved it to the c folder and same thing.

Gloop25 2018-07-06 -5 points

the fix cd thing doesn't work plz help me

MrJingles 2018-06-25 -1 point

MW3 and XP are in my opinion the last best Mech titles that ever were and ever will be. Everything after it has been a drop dead replacement, at this point your cloning zombies its dead leave it buried and move on.

I download the 119mb file and nothing happens, doesn't go to my C drive, no compressed file to extract what gives? I was able to download the 119mb version of MechCommander with no issue, however music and video files are missing, is the 500mb more complete?

i miss the nostalgic days of MW3 and pirates moon add on

Feckingwrecked 2018-05-08 1 point

is anyone else having trouble with the MFB's not repairing your mech? the game runs fine but for some reason it wont let me repair my mech, yet I can have them repair my allies mech...

Kairie 2018-04-19 0 point

Couldnt figure out the mw4:m download so here i am, grabbing this, and pirates moon for nostalgias sake.

Gjammer 2018-04-03 1 point

This site is great! This is the third game I've downloaded and successfully installed from here on my Windows 7 PC. I'm running it in XP compatibility mode. I remember the fuss people made about Mechwarrior games when they first came out. I didn't try them out back then but now I'm making up for lost time. 2018-01-09 -1 point

every time that i ran this game,thought my pc is fucked!
OMG! it was a video game!!!!! :O

Anyone who has problem with the mission 2, I just installed this app and locked the FPS to 30 and I just successfully completed it without any issue:

_alayra_ 2017-10-16 -3 points

undertaker 2017-09-29 -1 point

Anyone used to play mw3 or mw4 on msn zone?

???? 2017-09-24 -2 points

So you unzipped the folder and then do what now? I need instructions windows 10.

Strider 2017-08-09 1 point

I have no idea how to even begin to make this work. I unzipped it. Now what? Running Windows 7.

StoneWall 2017-07-17 0 point

Here's how you fix bouncing MFBs, graphic glitches, jump jet bugs, etc.

TLDR: cap your frames to 30, don't use a No CD patch, don't use compat mode

Ill try to install the radeon patch later. but I don't have time for that right now cuz im using some old amd radeon gpu

enferno 2017-05-25 0 point

I have a problem. I installed it on my win xp pc cuz it probably had some compatibility issues on my w10 pc and the game ran smoothly but in the campaign the enemy mech was walking underground, shooting me , the apcs were bouncing around like stupid. and the screen kept flickering white approx. every 15 sec even outside missions. instant action worked well but still kept flickering. the tutorial I tried once but I couldn't quit the mission in the end for some reason , I haven't tried to run the tutorial again but I don't need training cuz im used to MW games. also I have the patch installed but the fix I couldn't install cuz some error always kept popping up. I used the ISO installation

For those of you missing MSVCP50.dll, you can find a clean copy of it (I just ripped it, myself, from an XP installer disc) here:

Copy that to your installation folder. If you play more games from the 90s that use that dll, you can place it in \Windows\system32.

If Op 1 M2's turret isn't spawning, force enable v-sync and make sure you have your frame rate limited to 30 FPS (with RivaTuner or EVGA PrecisionX or... whatever your preference is).

Cascarus 2016-10-09 -2 points

the radeon fix doesn't work for windows 10 and my gcard is a AMD Radeon HD 8470

RedPhx 2016-05-28 2 points

Haven't played this one in a long time. Mechwarrior (1) I just got and would need to learn the controls before saying what I think. Number 2 and 4 I haven't played yet. As for MWO as long as you don't mind having horrible teams for about 90% of the pug games its a good game but its frustrating to try and buy a new mech or improve the skill on the ones you have if after you get a good score your team loses cutting your gain in half.

Zero Senki 2016-05-25 1 point

I love Mechwarrior 2 a lot, but it seems I left myself out of a possible gem here. Mechwarrior 4 had some good gameplay in my opinion. Athough I respect the opinions of Surivirus, I liked Mechwarrior Online.

SuriViruS 2016-03-18 1 point

thnx for sharing. MWO is still pretty....half-baked. And don't mention MW4 - pah

mechz 2016-01-27 9 points

I know everyone loved mw2, but mw3 will always be my favourite. annihilators were in my nightmares!
