As you can see from the title, I would need to decrease the maximum megaman shots (3) in 2 megabuster shots.
In summary, instead of 3 shots would I put 2. |

Find the specific 0x03 byte in the ROM that controls this and put a 0x02 byte there instead, using a hex editor. Try each 0x03 you can find, in order, and don't forget to put them back or you'll irreversibly render your game unplayable. ____________________ Wife make lunch - Shampoo Opera - give it a spin Spare some of your free time? <GreyMaria> I walked around the Lake so many goddamn times that my sex drive was brutally murdered Kawa rocks  — byuu |

It's not entirely clear from the post, but I'm guessing he's talking about Mega Man 1.
While somewhat reasonable, Kawa's suggestion would've been a time sink and gotten you nowhere, since the value you were looking for is actually #$05, not #$03. The byte you're interested in is at $16762. This byte is 2 more than the maximum number of shots Mega Man can fire; you'll want to set it to #$04 to allow only 2 shots. The game will allow unreasonably large values, and Mega Man can shoot up to 28 shots onto the screen at one time without changes to the bullet speed (maybe more if you abuse zipping?), but the behavior of shots beyond the 14th will likely be wrong because those will be placed into enemy slots instead of friendly slots (there are 16 of each). I don't recommend making it even that high because other things may use friendly slots, as well. The code for this is in the MegamanWeaponFire_P routine in the Mega Man 1 commented disassembly located at http://bisqwit.iki.fi/jutut/megamansource/maincode.txt. I located it using the FCEUX debugger by checking to see where some values in RAM (velocity, IIRC) for Mega Man's shots were coming from, and looked at code in the area. I hope that's helpful! |

Ah, whoops; I saw this thread in isolation and wasn't aware of his Mega Man 3 and 4 questions. Good catch. |

it's called hex editing, and hex offsets...it's best if you use the FCEUX emulator...open it's hex editor and go to the $xxxxx location.
as i said at the very top of the guide i linked you... **In a Hex Editor, open up in ROM Viewing mode. (FCEUXD Recommended). Here's a list of known data found so far. The mega buster is at 3D34D type a number 02 there, click save on the hex editor your done. It will only make you shoot 2 shots maximum instead of 3. --------- here's a shot, just follow what i just did right here exactly, and you'll have what you asked for. http://www.a3share.com/members/1119/hex-ed-shot.PNG |

You can send me a link to FCEUX 2.1.3, because I do not understand anything x( |

now ya wanna know about megaman 5 ?? i thought you were asking all these questions about mm3...
im really seriously getting confused on what the hell it is your even putting your attention on.. dont know about mm5 stuff honestly. MegaFLE can edit mm3, 4, and 5's weapon colors. but that's all, in reguard to weapons. |

Hold on. Decreasing the maximum number of shots per volley from three to anything below that value does not equal "infinite weapons" in any way, shape or form. ____________________ Wife make lunch - Shampoo Opera - give it a spin Spare some of your free time? <GreyMaria> I walked around the Lake so many goddamn times that my sex drive was brutally murdered Kawa rocks — byuu |

Wow it's really strange how you keep alternating between games, I'm guessing you wanna edit the one you can get the most information about.
Well I'm not a professional hacker, but using common sense I found these for Mega Man 3 (I guess the guy that has written something more to this in the Datacrystal database was you Kuja) 0x03D34D - Mega Buster(03) 0x03D34E - Gemini Laser(01) don't touch this, if 02, the gemini laser will pop onto the screen at random locations and may or may not damage what it hits 0x03D34F - Needle Cannon(03) 0x03D350 - Hard Knuckle(01) If you make it 02 then it will fly at double speed but breaks the game if shot at a breakable wall 0x03D351 - Magnet Missile (02) 0x03D352 - Top Spin (00) I have no idea what happens if you touch this, sorry
0x03D353 - Search Snake (03) 0x03D354 - Rush Coil (03) 03 because 1 is for summoning Rush and you can fire 2 buster shots too 0x03D355 - Spark Shock(02) 0x03D356 - Rush Marine (03) Same as RC 0x03D357 - Shadow Blade (01) 0x03D358 - Rush Jet (03) Same as before |
