There is also an unofficial patch for first Master of Orion currently in development. You can find it here.

NOTICE: Due to recent changes to Realms Beyond forum structure all old links to the forums and attachements in it have ceased to function. I've fixed the link above but kyrup needs to reupload the patch to Realms Beyond. Meanwhile you can download the patch from Petrell's Domain's Downloads section (moo folder).

Current version: 1.40m

Important:
!! Before you patch/play, you should BACKUP your Moo folder. !!
- Unzip the files into your Moo folder and play.
If the game crashes (or you experience a bug), go immediately to the Moo folder and conserve for me the save7.gam file - please.

version 1.40m
----------------------------
- no more eternal alliances for AIs (reverted back to the vanilla version)
- the missiles now use correct to hit bonus against ships with high missile defence
- at least 5% of missile will always hit (was 6%)
- AI huge, armored ships now cannot cause a negative overflow (prevention taken, maybe not a bug)
- the game now uses "Controlled Barren" on the Race report screen instead of strange "Control Barren ENVIRON"


version 1.40i
----------------------------
- 4th colony ship curse removed
- nebula speed and nebula ETA should work correctly when launching, with transports and ships having the same speed
- [bug fixed] AIs now actually take their treaties in consideration, when asked to declare war on their allies
- annoying bug / cheat when a fleet with bioweapons automatically bombed an enemy planet while orbiting is gone for good
- during strategic bombing, the game now actually checks whether you have your latest researched battle computer on board of at least one orbiting ship before giving the bonus
- the 'Wait' button allowing to fire unlimited number of rounds with unique weapons (pulsars, projectors etc.) during the combat - fixed
- the 'Wait' button triggering the repeated auto-repair function of a ship during the combat - fixed
- AI clears his spies' missions when succesfully threatened
- entering the general "threaten / break treaty" dialogue no more equals to a penalty of -100 to all temporary diplomatic (see OSG; is reserved for the concrete threats)
- the Meklars now can build up to # 2700 factories on a planet [credit to Lydon]
- the tech tree generation routine now checks for presence of at least one planetary shields tech for every race (see OSG)
- the Silicoids don't have the planetology techs useless to them in their researchable tech tree
- NEW: fixed an important bug preventing the right distribution of the AI big fleets in the mid-late game

interface
- the annoying Scout II redesign feature lives no more [credit to Lydon]
- the discovery percentages on tech screen are no more only 1/2 of the true probability of a tech hit
- AI sabotage message continue = space
- Psilon Leader "Zygot__" Name Correction: (removed empty spaces after name) [credit to Lydon]
- reenabled the cursor over the star
- the game autosaves every turn after the 7th turn into your folder

-------------------------------------------------------------

embryonic stage - included if not in "regressions"
----------------------------
bugs corrected

- the races now have the appropriate choice of objective at the beginning of a game
- the AI now uses the right race and the right objective when it takes decision about where to allocate the research points
- the spies you educate on the same turn against different races are no more overpriced
- breaking a NAP / alliance no more positively contributes to your rellations with the AIs (-10, -20 respectively)
- the player (AI or Human) who commits an oath breaker is not taken as a victim anymore, but as the tresspasser
- combat transporters now work, subspace interdictor works against them
- 8th stargate bug corrected (no ship maintenance overflow)
- bombing damage with torps halved, normal damage with missiles (was the contrary)
- AI-AI positive diplomacy problem corrected
- the AI now correctly uses the radius of action during its decision making
- the AI intentionally aggressive fleet positioning during the final war now actually works
- a small issue concerning the change in AI defence and ship production when too many MBases on a planet, has been corrected
- the Guardian now gets on impossible Adv.dam.control, hard gets Adv.rep.system, others none (was Adv. dam.control only on hard )
- the research BC now get no 90% discount when starting new technology project
- Silicoids do not have unusable techs in their tech tree: they now always get the Cloning tech

flaws (= not exactly bugs, but clearly not intentional issues)

- Bulrathis bombing decision when they are orbiting a planet and have transports incoming corrected to reflect their race gropo bonus
- Alkaris and Mrrshans bonus for AI-AI combat corrected to reflect their race bonus
- early tech decisions corrected to include a fourth decision point for all AI races
- all diplomatic temporary modifiers are now really capped at 100 (was 109)

interface changes

- you may 'continue' a game directly by running starmap.exe
- the game autosaves every turn in save9.gam (for the purpose of bug reports)
- "SPACE bar" = continue, process to the next / works now on many screens
- hotkey "A" = accept dispatching of a fleet, transport etc.
- side cursor works for a single slider on a screen
- rehaul of TECH screen, TAB runs through tech fields, hotkeys, the diodes lit under the tech level show when you reach max research bonus
- rehaul of RACES screen, hotkeys, clickable portraits bring REPORT page
- REPORT screen shows name of AI leaders, MAP screen shows current year
- after running through the Next turn phase + extra messages (shield build, max pop reached...), the game always recenters on your last planet of choice

Bump the important post.

Bump.

Bump.

Somehow I overlooked this thread.
This is great stuff, man! I have to get a few games in with this patch before I can truly appreciate the changes, but I like all of the little interface improvements (they are the most obvious), like clicking a portrait in the Races screen now automatically brings up the relevant report.
Edit: yeah, this was intended as a bump, too.

Updated to 1.40m

Most importantly, an "eternal AI alliances" problem created by the patch was removed + a few other points.

Thanks for headsup. Updated the first post with latest version info.

given the sale>>>Bump

I have tried to use the patch but it crashes the game on start up.

I have copied the patch folder to the Master of Orion 3 folder and extracted all files (3 of them) to the Master of Orion 3 folder.

When I try to start the game I receive a black screen and the program crashes.

I am doing something incorrect? I would dearly like to get the game patched to be more enjoyable.

Thanks

This patch is for Master of Orion 1 -- for MoO3 you have to find the patches which are named after different flavor ice-creams. There should be a link in another thread further down.

Sorry, my mistake...I will try on MOO1

Tried this patch for the first time yesterday. Started with 5 opponents. down to Humans, Meklars, and my Sakras as the true powers. Have been keeping the last remnants of Darloks and Silicoids in a constant state of revolution. Mr`shanns were wiped out by the Silicoids. The cool thing is my non-aggression pact and trade deals with the Meklars have never been broken.

It is only now as i remove all those Human scum from the best planets of the galaxy that tensions have begun to rise with the Meklars (The humans keep asking to end the war, but they won't offer me their Earth Women, so the war goes on). According to the status reports, my biggest advantage over the Meklars is my population base, followed distantly by my tech advances. The rest is almost neck and neck with me holding a faint advantage. When diplomacy fails, it is going to get ugly..

Before this patch, I would have been at war with all the races before I had 15 planets colonized. Much better balanced, good work!

I patched the game but it still says version 1.3. Is there anything I can look for which will tell me if I successfully patched the game or not?

Go to Map ("M" button) and you should see there: "Year 2100" or whatever year it is.
If you do, you're patched.

(I could not get rid of the "version 1.3", because it is a part of an image rather than an inscription from a file. Annoying, I know.)
