What is this page?

This is MURB's Hack-9-Hack page. It provides a patched Hack-9 file which will make the game Hack-9 easier to play though success will be less legitimate.

In short, the patched file is a cheat intended primarily for beginners and others who'd like to take a look at the Hack-9 world.

This is a draft page that may move. MURB will keep the Hack-9 community apprised of links.

MURB says:

In the year 2008, the Japanese developer BLACK BASTARD (wahiko94) released a modification of the hit independent side-scrolling computer and now video game Cave Story.

This modification was named Hack9, and though it definitely borrowed heavily from Cave Story in terms of physics and, to a lesser degree, certain graphics, was a distinct game unto itself.

Interesting and impressive though it was, the game was nigh impenetrable for non-Japanese speaking gamers.

Only recently, as of the year 2018, has Hack9 become available in an officially sanctioned English translation. It can be found on the following page:


There's an English README file at this link. The developer's home page is: https://wahiko94.at-ninja.jp/

One thing folks will note upon encountering Hack9 is that it's a very difficult game.

There's a legitimate way to make the game easier, but this comes at a significant time cost.

Both the HP and MP stats of the main character of the game — named Snort after the networking utility of the same name — can be boosted using items provided by a vendor who appears in the first area of the game.

Alas, obtaining the in-game money to get these items involves significant time cost to grind out the necessary in-game yen to obtain them.

Ordinarily, one accumulates these yen by playing, but being a video game player of no particular skill or patience I felt that I would need those items first in order to play the game

Presented with this chicken or the egg problem, I developed a different idea: what if I hacked the Hack9 save file to give myself the currency needed, straight out of the game, to buy out the item vendors?

Many exploits tainted with ineptitude, idiocy, and inadequacy later, along with help with tool development from a respected mentor who is making this file available to you on his server...

OldCoder says, Shucks, t'weren't nothing

... I managed to achieve my goal and create a save file with an astronomical amount of money, progressed to just shortly after the very beginning of the game.

One is spared a bit of exposition and the tedium of having to procure both starting items and the 198 items available from the vendor in the first area of the game that boost HP and MP, already pre-applied (because using 198 items is exceedingly tedious).

For those who want to play Hack9 with this file, please be warned that it will probably suck most, but not all, of the challenge out of the experience of playing it.

If you'd like to try the file, proceed as follows:

* Exit the game.

* Your existing GAME_DATA.DAT file should be located in the same folder as hack9.exe. Rename the file to something like GAME_DATA.OLD. Or just delete it, but this is riskier.

* Click here to download hack9hack.zip.

* Unpack the ZIP file in the same directory as hack9.exe. This should create a new copy of GAME_DATA.DAT.

* Play the game.

* To get the original mode back, exit the game, delete the new copy of GAME_DATA.DAT, and copy the renamed copy back to GAME_DATA.DAT.
