Genesis


--
Sega Genesis - Lotus II RECS - Timer Doesn't Decrease
Note: This is my first ever Game Genie code (for Genesis).
In this example, we will find the emulated RAM address for time using Cheat Engine.
After that, we will find the emulated ROM address that effects the emulated RAM.
And finally we will use a hex editor to edit the actual ROM address (the game it's self).
So, open Cheat Engine v5.6.1(+), then Fusion v3.64(+).
Use Cheat Engine's option to attach a debugger to the emulator.

Note: Click on an image for it's full size.
Change the value type to one byte.

Use the emulator to load the attached (below) Genesis game:
Lotus II RECS (UE) [!].gen
Thing to know about Fusion:
Tab key = Reset
F5 key = Save
F8 key = Load
Backspace key = Fast Forward
Pause/Break key = Pause Emulation
Alt+G = Game Genie / PAR / True Emulation Pause
Press start over and over until you are in a race and see a timer on screen.
Once your in the race use the Pause keyboard key to pause emulation.
Press F5 to make a 'clean' save with no RAM/ROM modifications.
You should have 69 seconds to begin with..
http://img407.imageshack.us/img407/2100/pausef569seconds.png

With emulation still paused, use Cheat Engine to make your first RAM scan for the time of 69 seconds.
http://img34.imageshack.us/img34/5061/firstscanis69seconds.png
Press the Pause keyboard key to resume emulation, but only until the timer goes down a second, then re-pause emulation.
With 68 seconds showing on the game, make your 2nd Cheat Engine RAM scan for the new value of 68.
http://img192.imageshack.us/img192/9492/secondscanis68.png

Repeat as necessary until you are down to 2 possible results.
Once you've added the 2 results to your Cheat Engine code list, freeze one at a time to see which one is the correct address.
http://img10.imageshack.us/img10/3541/twopossibleramaddresses.png
Note: Your address shown in Cheat Engine are likely different than mine..
At this point, you could optionally use Alt+G and CE to convert the emulated RAM to AR (Actual Ram a.k.a. Action Replay).
http://img808.imageshack.us/img808/1869/ramemulated2actual.png

Now that we have an emulated RAM address for time, let's see what emulated ROM addresses modifies it.
Since that other useless RAM code will only cause confusion/get in the way, I'm gonna delete it from the CE code list.
With emulation paused, right-click on the good RAM address and choose Find out what accesses this address.
http://img689.imageshack.us/img689/9163/whataccessestheram.png
Resume emulation until the debugger shows that something accessed the RAM, then you can pause the emulator again.
Almost always, there will be 2 addresses shown in Cheat Engine's debugger, you can go ahead and click the stop button on the debugger.
http://img89.imageshack.us/img89/9140/stopdebuggingif2address.png

Now, you could have earlier, but you should by now un-freeze the RAM code in Cheat Engine.
You need to watch if the RAM value decreases or not, when testing your ROM modification.
You wouldn't want false hopes by accidentally leaving the RAM locked.
So do that, un-check the RAM address if you haven't already..
As far as the two address shown in the debugger; usually, but not always, the first line is reading the RAM.
The second code is usually the one we are after, the address that is writing to the RAM.
So now we double click the 2nd line, or highlight it and click the button that says More information.
http://img340.imageshack.us/img340/2756/doubleclickformoreinfor.png
Note: Again; the numbers in the images don't have to match yours..
In the new information box that pops up, ESI will always hold the address that we are interested in.
If that's not the exact code that we want, it's extremely close.
That address shown is our ROM address, and the last possible one.
If that's not the correct address, you subtract 1 from it until you have the correct one, you never add 1 to the address.
OK, so with the info box still open click the button add address manually.
Change the type to byte and type in the address at ESI to add it to your CE code list.
http://img211.imageshack.us/img211/7199/manuallyaddesitoce.png

Now, with the RAM unfroze lets try to NOP (00) the newly added ROM address.
Remember to have made a save, if your ROM altering is no good, just press F8 to load.
If you press F8 to load and the original ROM byte that you NOP'ed didn't come back, you'll need to load the game instead (or manually insert the original byte).
The game instantly froze after pressing the Pause key, so this address is no good.
Reload the game or whatever is needed to get back to the same spot.
Now we simply subtract 1 from the hex address, never add 1, always subtract.
Actually 9 times out of 10 you'll need to subtract at least 1 from the address given in the more info box..
http://img263.imageshack.us/img263/7660/subtract1andtryagain.png
So I just modified the code that was already in the CE code list by subtracting 1.
I then NOP'ed that address instead, for a now second try at a ROM code.
I start playing the game (yeah, didn't freeze this time) and watch the RAM address in CE to see if it decreases.
It never decreases, so the ROM modification is a success.
As usual, I subtracted 1 from the 2nd address given from the debugger for a successful code.
http://img340.imageshack.us/img340/8927/secondbreakesiminusonei.png

That was all it took for me, but if you still haven't found the correct ROM code:
1. Keep subtracting 1 over and over. If you do this over 10 tries, it's likely the wrong base address.
2. Remember how we started with the second break in the debugger, try the first..
Now, to convert the code from emulated ROM to actual ROM.
This is easy, just right click on your successful ROM code and choose Browse this memory region.
The top left byte is your ROM code, and the next few bytes after that is what you want to use to locate the code with the hex editor.
http://img52.imageshack.us/img52/9303/topleftbyteistheromcode.png
So with this window open, we know to search for 4E 75 72 00 30 2C 00 0E EE 48 02 40 FF F8 32 in the actual game.
So open the game with the hex editor and search for that string of hex values..
After locating the string, just replace the 0x20 before it to 00 for Infinite Time.
http://img257.imageshack.us/img257/7969/patchthe20to00forinfini.png

So after editing the 20 to 00 choose save as to not over write your ROM.
Open the newly created ROM with the emulator without anything changed in CE to test the mod out.
If you didn't use a program to fix the checksum of the ROM after altering bytes, just use the option in Fusion to auto fix checksums.
http://img844.imageshack.us/img844/8525/autofix.png

Damn, this game wasn't the best example (that's what I get for making a guide with my first try).
The game still won't boot, even if you fix the checksum.
Luckily, Tony Hedstrom made a Master Code for this game, to solve the problem.
Master Code (by Tony Hedstrom)
RH9T-860T (0FFFD0:4E71)
Use this code if you get a blank screen.
So, you can try out our hack by either:
1 Input the Game Genie code to bypass the black screen
2 Open the ROM, goto the hex offset 0FFFD0 and type 4E71 to hack your ROM to bypass the black screen
I can finally play the game and the timer indeed does not decrease.
But, at the same time, I notice a small glitch happening.
Anytime a code works, but not exactly as planed, you should try subtracting 1 again from our ROM code.
In the image above, you can see that before the 20 we patched to 00, there is already a 00, so we actually need to subtract 2.
Now we'll try to change the 6C to 00 and hope for a less buggy code.
Success, seems to work fine..
So the actual ROM address of 010E95 was changed from 6C to 00.
Since 010E95 ends with an odd number, subtract 1.
After that write down the 2 bytes that we want our Game Genie code to write.
So therefore:
010E94:5300
http://img811.imageshack.us/img811/1943/evennumbers.png
That's the ROM address, you can now convert it to Game Genie.

Cheat codes have been around for as long as there been video games. But how did they come about? How did word of their existence spread? Did game designers intentionally put them in, or are they accidental exploits? There's a lot of history behind cheat codes, and it's about time we revealed their untold truth.

They began with a lot of POKEing and prodding

Cheat codes started when tech-savvy gamers in the early days of the home console market would modify the values of a game's code by overwriting its memory and adding in numerical values that altered the gameplay experience. Players had to go through the arduous process of first finding individual lines of code, or POKES, as they were called, and changing them—then they'd cross their fingers and hope the new values did something. A lot of people wasted a lot of time with trial and error just so you could quickly and easily mash some buttons to have infinite health potions.

They were shortcuts that allowed everyone to cheat, even a game's developers

While cheat codes are just ways to give yourself an unfair advantage, that wasn't always their intention. Some cheats were added into games as shortcuts so developers could more easily navigate their game during testing. A cheat code was a quick and easy way to break the game for easier access to its individual parts. An example provided by veteran developer Chris Sorrell was a cheat that could kill a boss in one hit:

'You can't keep fighting the boss just to check if he correctly drops the special key as he dies, so you add a weapon super-power feature to kill him in one hit. Spending just a little time hooking up powerful cheats means that you save yourself–and everyone else working on a project–hundreds of hours of productivity time.'

Often times these cheats were left in the game by accident, only later to be discovered by crafty gamers. One of the most famous debug cheats that made it into the final release was in a game called Manic Miner, released on the ZX Spectrum in 1983. Designer Mathew Smith used his driver's license number, 6031769, as the cheat code that unlocked a secret level select mode, allowing players (and Smith himself during development) to jump to any level.

Cheat codes soon hit the mainstream

Soon, POKEs—or cheat codes, as they would soon be more commonly known—made their way into video game magazines. Every gaming mag on the market had a section dedicated to listing every known cheat code of the most popular games of the month. Eventually, there was even a magazine solely dedicated to cheat codes, titled Tips and Tricks. With this came the development of cheats specifically inserted into games by developers as Easter eggs for players to unearth, read about in a magazine, or hear from a friend, that would let players add extra layers of fun to their experience as they pleased.

Enter the world famous Konami Code

Without a doubt, the Konami Code was the most famous cheat of all. By entering up, up, down, down, left, right, left, right, B, A, in Konami's 1985 classic side-scrolling shooter Gradius, designer Kazuhisa Hashimoto gave the player-controlled ship additional weapons. The code wasn't originally created with the general gaming public in mind, though: Hashimoto did it to give himself all the help he could get because without it, there was no way he could beat his own game. Just a few years later, the same code was used in the development of another Konami hit, Contra. Entering it gave players 30 lives rather than 3, which made the notoriously difficult game somewhat easier to beat. The code became so well-known, Konami went on to add it into dozens of its titles—and it's shown up in hundreds of games from scores of publishers over the years.

Cheat codes that fought the law

The 1990s were a golden era for cheat codes—a time when video games moved beyond the mainstream and became a dominant force in the American entertainment industry. With the new level of success came intense scrutiny that, in at least one instance, cheat codes were used as clever loopholes. How to hack any android game with cheat engine. When Mortal Kombat came under fire from politicians and parents' councils for its graphic depictions of violence and intense gore, its developers were forced to remove the game's nastier bits for its Sega Genesis release—sort of. Mortal Kombat for the Genesis was free of blood and guts..until a player entered the cheat code A, B, A, C, A, B, B, which restored the cleaned-up, family friendly, but-still-super-violent version of the game to its bloody arcade roots.

And then cheat codes got weird

As cheats grew more popular, they became more about players being able to alter games in ways that were more amusing and silly than useful. Case in point: big head mode. No one is quite sure which game was the first to include this ridiculous cheat, but credit for popularizing it goes to the NBA Jam series. Big head mode literally made characters' heads much larger than normal—and that's it. It gave players no greater strategic advantage, but it would later appear in in hundreds of games, even making appearances in classics like Goldeneye for the Nintendo 64 and, later, Microsoft's Gears of War series. Where the most useful codes gave players unfair advantages, others, like some featured in Grand Theft Auto III, actually did the opposite. Developers at Rockstar added a code that made all the citizens of Liberty City go into a blind, mouth-frothing rage from the moment they saw the main character, compelling them to attack the player on sight.

The Game Genie and GameShark made cheating too easy

The popularity of cheat codes reached its peak when companies started building hardware to let players more easily input their cheats. Enter the Game Genie and the GameShark. Both were cartridges that were to be sandwiched between the console and game cartridge, and they brought order and ease to the chaos of entering and activating cheat codes. A signal sent from the cartridge would be intercepted by a Game Genie or GameShark as it was on its way to the console; before it relayed the message to its final destination, the device would alter the game's code to the player's benefit. They made cheating easier than ever before.

Cheat codes forced Nintendo to accidentally spark an evolution in the way we cheat

It's no surprise that Nintendo sued Codemasters, the developers of the Game Genie—but not for the reason you'd expect. Nintendo claimed the device was creating an illegal derivative of their original games. When Nintendo lost the case, the gaming community at large interpreted as meaning one very important thing: modifying games after purchase was legal. Game Genies and GameSharks were, in essence, modding classic 8 and 16-bit games in real time. And if that was legal, then it must be legal to make a mod for Skyrim that gives all the female characters really big exposed breasts and turns all the dragons into Thomas the Tank Engine. The modding community of today's gaming world owes quite a bit to Codemasters.

Internet killed the magazine star

With the internet's rise to prominence, cheat codes went digital, and much of their moneymaking potential disappeared. Why would a monthly videogame magazine need to publish an entire section dedicated to cheats when there were websites dedicated entirely to cheat codes readily available 24 hours a day?

Over-achievements

Cheat codes aren't as prominent as they used to be, but it wasn't the internet that killed them. According to veteran videogame journalist Dan Amrich, the core satisfaction gamers were filled with when they used cheat codes was eventually duplicated and intensified by the achievement systems on Xbox Live, the PlayStation Network, and Steam. 'Cheat codes were no longer the currency of hardcore gamers once Achievements appeared,' argued Amrich. 'They were another creative outlet for dev teams and they were required by Microsoft, so the effort that would go into cheats went into Achievements instead.' Why brag about your knowledge or usage of the cheat code when you can brag about the things you've been able to accomplish in a game without cheating?

It's a modder's world

Game Genie Codes For Nintendo

Cheat codes are far from extinct. Person cheats in marketwatch game because games chart is slower. They'll always exist in some form or another. Maybe not as a series of button-mashing combos, but as something else entirely. After all, if you can mod Skyrim to make your character invincible and turn your character into Link from the Legend of Zelda series and to swing Finn's sword from Adventure Time to fend off mudcrabs that have been modded to shout profanities when hurt, you're definitely still using cheats.
