It would be a nice thread on here, to see what people's first hacks were, especially from that era when people were usually just alone and stumbling on these things.

While not the first hack by a long shot and not even mine but I always loved the idea of how it worked.

There used to be program called Gamehack or something like that. Essentially you would start the game and point this application at said game in RAM, then take note of something like the score being "187" or whatever. Jump into 'Gamehack' and it would search for everything in memory with that value. You would then play for a little bit longer and once the score had changed, you could then jump into game hack and find which of those memory addresses had changed to the new score. Usually you would only have one, you could then change this number to what ever you wanted.

It was such a simple concept but it worked so well. Wouldn't be able to do something like that anymore due to all manner of sandboxing in action. Lost a tool, gained security.

Only other hack was messing with the vehicle stats in Vice City. Ended up with the firetruck that could jump the entire map. Good fun.

Saving a game in Bard’s Tale (for Amiga). Buying an item in a store. Saving the game again. Comparing the save files with a hand-rolled AmigaBASIC hex dumper to find the bytes that changed. Working out from there how it stored money balances in the file. Tweak a little… and voila, everyone in my party’s getting mithril plate and frost horns.

Mine was very simple, just finding and playing with values in config.ini for Red Alert 2 so that I could have infinite Tanyas and such.

Next step was trying to get the boot screen to display a MS-branded Borg cube but instead bricking the machine. Parents were not thrilled about that.

My first was almost kinda similar to GP: me and my cousin played a game called ReVolt, and found that you could make the cars go faster by changing their speed attribute in some text file we found just poking around the game files.

Man we had some good fun with that! It always ended with us boosting our cars so much they flew out of the map

Bypassed the anti-piracy manual check in the second Championship Manager[1] game for my buddy. It was a typical check at the time which in this case asked you to reference a table of soccer matches in the manual and enter the correct game results for one of the games, ie 1-3 or similar.

I had been teaching myself programming for a few of years and had recently gotten my hands on Turbo Pascal. I had just started dabbling in assembly as well. So I launched the game through the debugger and by stepping through functions, in assembly obviously since I didn't have source, I finally got to the place where it waited for me to input the game results.

It encoded the game result in a single register, and compared the value in that register to a value in another register which it had loaded the correct value into.

Using the surrounding code, I located the byte in the executable and replaced that one comparison instruction with one which compared one of the registers with itself, which of course was the same all day err day. Wrote a small program to apply the one-byte patch.

Took a lot of time, especially tracing to find the right place since I wasn't very good at using the debugger nor that proficient with assembly. But very satisfying when my buddy could just enter whatever result he wanted and enjoy the game.

After that I dropped cracking games and focused on save-game cheats which I did for a while until games added sanity checks or just had very dynamic save-game formats.

Me as a kid realizing that the rate of fire on the shotgun was directly tied to the number of animation frames in the original Doom. Cue mecha super-extreme gatling shotgun and also mecha super-extreme choppy frame rate.

Hitscan weapons for the win.

Ooh the Dungeon Keeper demo actually had all of the characters, just not the art assets. So when I was 11 I modified the ini file and had invisible giants and vampire lords doing my bidding in my dungeon. I was very proud of myself.

The whole cracking scene was where a lot us cut our teeth learning to use machine code debuggers.
