#gamegenie — Public Fediverse posts

I'd love to see a #GameGenie like device, for the NES foremost, where you can add IPS files on a SD card much like an #Everdrive. Then, through the magic of memory manipulation, patch the game in real time with whatever files are set to be applied.

Imagine having an original NES game, plug it into your #GameGarble™ and now it's a completely new game! Or, now you can understand it! Or, now that annoying feature in the original is fixed! The possibilities are endless.

@krikzz - hit me up

Here's an interesting NES Game Genie code: ZZSZZZZZ.
- In l33tsp33k, it's 22522222.
- Decoded to hexadecimal, the code is... also 22522222. That is, address 0x2252 (or 0xA252), replace value 0x22, compare value 0x22.

I put the instructions on how to build the Game Genie code wheel on my home page too:

How do Game Genie Cheat Codes ...

I think I finally figured out how to build a 7-disc code wheel that decodes and encodes 6-letter NES Game Genie codes. In short: one wheel exposes a pair of small and large digits and another wheel hides one of them with a checkerboard pattern of holes. The text file is screen reader unfriendly.

🎮Ah, the Game Genie: because who wouldn’t want to turn their NES into a buggy mess of cheat codes that doesn't even have Nintendo's blessing? 😂 Now, marvel at how a glorified glitch-maker became a pivotal moment in copyright law—because nothing screams legal precedent like hacking Mario to jump into oblivion.🚀

Game Genie Retrospective: The Best NES Accessory Ever Was Unlicensed

How I found the Game Genie codes using FCEUX:
1) By looking at the CHR ROM, I knew I wanted to use tile 0xd2 instead of 0x0a and 0xd7 instead of 0x0e.
2) I looked at RAM in Hex Editor. A copy of sprite data was at 0x0700-0x07ff. The cursor was in the 2nd sprite slot, so the tile was at 0x0705.
3) I set a breakpoint on 0x0705 write in Debugger. It found STA $0701,X. The previous instruction was LDA ($00),Y. Whenever that was run, RAM 0x00 contained 0x98 or 0x9d, RAM 0x01 contained 0xd8 and Y was 1, so a byte was being copied to A from RAM 0xd899 or 0xd89e.
4) Indeed, during gameplay, CPU address 0xd899 contained 0x0a and 0xd89e contained 0x0e.
5) I used https://www.nesdev.org/nesgg.txt to create the codes:
- XSOSOEZA = "if the CPU tries to read a PRG ROM address that's currently mapped to CPU 0xd899 and contains 0x0a, return 0xd2 instead".
- NSOSVETA = same but 0xd89e, 0x0e and 0xd7, respectively.

In the NES game Yoshi's Cookie, you may be bothered by the cursor obscuring the cookies (top row in the screenshots). However, you can replace the cursor in one of two ways:
1) Edit the iNES ROM with a hex editor to replace the cursor tiles with a blinking square in CHR ROM (middle row in the screenshots):
- 0xff818181818181ff0000000000000000 to 0x200b0-0x200bf
- 0x0000000000000000ff818181818181ff to 0x200f0-0x200ff
2) Or, use these Game Genie codes to replace the cursor sprites with sprites that look like hands (bottom row in the screenshots): XSOSOEZA + NSOSVETA

I've noticed that there's been stuff documented over on TCRF covering the Game Genie for SNES and Game Boy, but not the Game Gear. I will eventually try to make a video covering this and will try to recover my account there to get relevant information posted

👾​ The Game Genie was great back in the day. Here is my boxed #Nintendo #Gameboy #GameGenie and my loose #segagenesis Game Genie. I also have a PS1 and PS2 #GameShark somewhere.

I still remember a serious conversation that I had with my dad about cheating in games. I was 7. He taught me to appreciate the game as the developer intended first and never consider yourself to have beaten a game if you applied any cheat codes to it first. So I always played my games the way the devs intended first, and used the cheat codes as a way to change or enhance the replay value only. I also only used multi-player cheats if the other player agreed to using them too. 🎮​

Reoccurring awkward moment: trying to get Game Genie codes working when one of the codes listed is "Master Code (Must Be On)" and trying to figure out if it's making stuff better or worse. :P

(Galoob was apparently wrong in the case of Donkey Kong Country 2, at least in my case.)

I couldn't stop with just the Analog Pocket. Here's the Game Genie for the Game Boy plugged into my Game Boy Advance SP-101
