Neocomputer is a site hosting retro computing projects, including a detailed analysis and fix of the Atari 2600 game E.T. The Extra-Terrestrial.
What HN saysHN commenters repeatedly link its E.T. article as a clear breakdown of the game's bugs and how a few small changes would fix them.

It was very close to being amazing (for the time), unfortunately an aggressive release deadline meant showstopping bugs. Check out this article from someone who fixed it: http://www.neocomputer.org/projects/et/

I presume many here will have seen this before, but a while back somebody deconstructed/explained all of the problems with ET and then went on to correct them (by hex editing the rom):

It's along very similar lines to this (also really great) post about the broken C64 listing.

I love that someone took the time and effort to fix the bugs in E.T.: http://www.neocomputer.org/projects/et/
mrspeaker · 2016-02-22
Anyone who is in to Atari 2600 knows that ET is verrrrrry far from the worst game available on that system! And it's so sad making it a great game would have take so few tweaks! http://www.neocomputer.org/projects/et/

Here's a great piece on how E.T. can be fixed with a few relatively minor changes:
http://www.neocomputer.org/projects/et/
As much grief as Warshaw has gotten for E.T., it really is an amazing accomplishment that he put it together in five weeks. (This is particularly true, considering the extreme resource impoverishment of the 2600 platform.)

there is a fantastic article about fixing bugs in the game, I am pretty sure that HN will appreciate:

Bad collision detection with respect to the character appearance, and the game not being understandable if you didn't thoroughly read the manual.

wombatpm · 2024-04-28
They did fix the game already. http://www.neocomputer.org/projects/et/

The main problem with ET is that there is a fault in the hit detection.

> You spend a lot of time accidentally falling in to wells. I believe that I know reason why this happens to so many people, and what can be done to fix it.

This reminds me of the person who fixed the infamous Atari ET game: http://www.neocomputer.org/projects/et/
AnIdiotOnTheNet · 2022-07-28
It was also plagued by some very annoying bugs, which have since been fixed: http://www.neocomputer.org/projects/et/

Here's someone cutting the game open and editing the assembly, to improve it by various means: http://www.neocomputer.org/projects/et/

Atari: Game Over made for a really interesting watch in explaining what the game was meant to be, and how it works
There's also this treatise on why people thought it was broken, and how to fix it:

and someone fixed ET years later.

> Eller's algorithm creates 'perfect' mazes, having only a single path between any two cells, one row at a time. The algorithm itself is incredibly fast, and far more memory efficient than other popular algorithms (such as Prim's and Kruskal's) requiring storage proportional to only a single row. This makes it possible to create mazes of indefinite length on systems with limited memory.

For me, that would be Eller's algorithm: http://www.neocomputer.org/projects/eller.html
It generates perfect mazes of arbitrary size M*N, using only O(max(M, N)) memory.

And the bugs have been fixed:

Actually E.T. was all right, after you read the manual and fixed the few release bugs [http://www.neocomputer.org/projects/et/]
bluedino · 2014-04-26
Some guy fixed most of that stuff - http://www.neocomputer.org/projects/et/
