Patches are provided in xdelta format.
We recommend the np21.exe build of Neko Project II for emulation. See our PC-98 Emulation guide for more details.

anex86 and T98-Next cannot play the HDI version of the original game, and builds of Neko Project II ending in “x11.exe” will freeze at the end of Chapter Four.

Common Issues

1. Chapter 5 battle text isn’t translated, but the rest of the game is?

This was a bug that we have hopefully fixed already. Try redownloading and reapplying the above patch. If you’d like to transfer your save file from your current game, you’ll need to get a program called EditDisk and open your current User Disk, then extract the PC1.46 to PC6.46 files (EVO Files 1 to 6), and then transfer these files to your freshly patched User Disk.

2. I’m getting a checksum error on the User Disk of my FDI files?

This problem is a little more difficult to solve. The way a User Disk works is that, normally you have to create your own User Disk using the System Disk that your game came with. It’s kind of like installing the game, except to another disk. So what happens is, most of the FDI files around the internet may have the same Disk B1 through B4, but they each might have a different User Disk made by different people at different times. It will be very difficult for us to create a patch for every single user disk out there. You may keep looking for a User Disk with the hashes given in the readme, but it may simply be easier to use the HDI or HDM patches, as these disks are available in a more standardized format.

3. Disk 4 of my HDM files is throwing a checksum error when I try to patch it?

We actually fixed this issue pretty quickly, so you might have an old version of the patch. Redownload the patch and try it then. Should work.

4. The game fades to black after finishing Chapter 4, and never loads Chapter 5.

This bug seems to occur in versions of Neko Project II that end in x11.exe. We’re looking at this, but for now, we recommend using np21.exe from the np2fmgen emulator pack.

About Game

E.V.O.: Search for Eden was released in the West on July 15th, 1993. It did okay, and became somewhat of a cult classic. So when we say the game that came before it called E.V.O.: The Theory of Evolution (46 Okunen Monogatari: The Shinkaron) published by Enix and released on the NEC PC-9801 system is more even more obscure, we might actually be understating how unknown it is outside of Japan.

E.V.O.: The Theory of Evolution is an RPG, about one step more primitive than the Dragon Quest games published by the same company. You control one character as they progress through the different eras of life on planet Earth, fighting turn-based battles with damage being based on stats that you control directly. Once you’ve pushed a stat to its uppermost limit, your character evolves into a completely different creature with different abilities in battle. The story itself is somewhat similar to Search for Eden, but much more fleshed out with a lot of different stories for each era that the game explores. And while Search for Eden ends with humanity as the pinnacle of evolution, The Theory of Evolution goes a bit further into the future…

You can read more about the game and its history on its Wikipedia article or over at Hardcore Gaming 101’s article about the E.V.O. series.

About Project

This is our first project as 46 OkuMen, as well as hollowaytape and kuoushi’s first romhacking project in general. So it’s been a long and exciting process.

Here are some fun things we discovered about the game and script along the way:

  • During the opening and ending cinematics, the game interprets any string starting with “A” as an image filename (ex. AV001.GDT), and crashes as a result.
  • The game supports a “brief pause” control code, but only incorporates it into the game script in the first chapter. The developers may have forgotten it existed while writing the rest of the game.
  • The science presented about the creatures in this game is actually quite accurate and well-sourced.
  • A few of the chapter titles reference specific things. One of these might not come through in the translation too well, but chapter one is actually a reference to the KAI-YU-KAN Aquarium in Osaka, Japan. The aquarium opened in the same year as E.V.O.: The Theory of Evolution‘s release in Japan, so they named the first chapter the KAI-YU-KI (or KAI-YU Period). The literal translation for those two characters is OCEAN-PLAY, which is how we came to the current translation in our patch. Another chapter title that underwent a small change was chapter two, which we have in the game as Coal Forest Period. The original Japanese, JU-RA-KI, is a sort of play on words with the two characters used for JU-RA referring to the forests spreading onto land, while the full JU-RA-KI also stands for the Jurassic Period based on the syllables alone. Unfortunately, chapter two doesn’t actually take place during the Jurassic, so it got tweaked.
  • The Teilhardorphus is named after the French Paleontologist, Philosopher, and Jesuit Priest Pierre Teilhard de Chardin, who was one of the people responsible for the discovery of the Peking Man. This is one of many of the creatures named after real people, most of which were named after people who worked on the game such as the Sugiyaman, which is named after the game’s composer, Sugiyama Kouichi.
  • Not so much a note about the game, but if you wanted to see what the Japanese packaging for The Theory of Evolution and Search for Eden looked like, sonofashark /Ultimate scanned and uploaded that to his Flickr account.
