AoE II HD Compatibility Patch
Download Patch
Introduction
This is a community created compatibility patch for those that have purchased Age2HD from Steam to support the running the game in a mode supporting the original The Conquerors release.
The purpose of the patch is to provide a quick and legal way to purchase the HD version of the game through Steam, and add compatibility with the regular Age of Empires II. This patch does not violate copyright, no files from the original CD are used -- more on this below.
Motivation
Reasons for using this patch include:
- The original AoC still has a large and active community, especially for the Multiplayer version. On Steam for e.g There is virtually no Custom Scenario community, yet other fan sites have larger and more active player bases.
- When Age2HD on Steam was announced many of us / the community were excited to finally have a quick and easy way to buy the game again and still be able to play with existing communities and friends. This turned out to not be the case. This patch fixes the drawbacks of isolating communities, and allows us all to now play together as we had originally hoped for.
- These fan sites for the original AoC and it's communities sponsor some large events, such as $20,000 Nations Cup or the $50,000 War is Coming.
- It is fair to say that while Age2HD has implemented some interesting stuff, it most certainly has quality and stability issues for a number of players. This patch provides a solution to those issues.
- Take advantage of the fan patches created for the original version.
- Age2HD on steam is a convenient way to purchase the game, while Amazon still sells it not everyone can buy from amazon.
Compatibility Mode Behavior
When playing in compatibility mode, the game will behave exactly as
it did in the original and the enhanced HD version , with community
made patches such as UserPatch.
Some Features will remain the same: HD resolutions will still be
available through the community patches -- please compare the
screenshots below.
Features disabled: the animated water won't be there.
Features added: any feature present as part of userpatch or the
multiplayer client use.
How this is Possible and Legalities
Compatibility mode is made possibly by combining either FE files (http://www.forgottenempires.net/install)
or the 1.0c patch from Microsoft for the original game, Age2HD data
files and a few small edits to 1.0c exe. There are no files included
from this patch off the original CDs and because of this doesn't violate
any copyrights.
OK, if it's not illegal wouldn't Microsoft dislike this? We hope not,
as the patch requires a full installation of AoK HD it definitely
doesn’t help piracy, anyone pirating the game can already get full
installations of the game available. Further, we expect this to only
gain more sales for Microsoft as it reduces motivation to pirate the
original game if there is a quick and legal way to get it legally.
