ROM Hack Hacking "Must Be On" Codes

[thela_kid]

Hey everybody at this wonderful forum, not sure if this was the right place to post this. I enjoy hacking my own codes but some games like New Super Mario Bros. require a Must Be On Code. Although I can download the cheat file maintained on this site, it does not apply to rom hacked versions. Any tips or links to how-to pages?? Thanks All

do you mean there's no cheats for it?

if so, it means that the cheat database doesn't support rom hacks, except with certain exceptions for certain translated games.

I mean that I want to hack my own "Must Be On" code and would like to know how.

Is a code..
is the ARDS fixed code (if i am not wrong)

I noticed while trying to hack my own codes, they would not work. From cheats.gbatemp.net/Temp, the usrcheat.dat file has "Must Be On" code for NSMB that allows the other codes to work. However this MBO code doesn't work for rom hacks. It is this code I'm looking for. Sorry if it's confusing :/

i have no idea why do you need that code?
the code is only needed if you are using the ARDS devices from datel
if i remember things correctly, you don't need that code for flashcart/emulators

the code enables a jump from 023807d40 to a specific address
i assume that address is where the ARDS handler is located (hopefully, i used the right term)

when you are talking abour ROM HACKS? i have no idea which one are you talking about
i will assume you are also talking about Mario

if you really keen on doing this yourself.... then you need to find out the following

-where should it jump from on the hacked game
-where should it jump to for both clean and hacked
-calculate the jump for hacked game

but why need it... if you are running on flash cart / emulators

If I am reading you correctly you are wanting to cheat on NSMB with modified levels? The header CRC is fixed so that means the cheat engine doesn't recognize it as the same game. You have to use R4CCE to edit the dat and add the game ID and codes. Alternatively, you could use DSATM to apply the cheats.

Ah thanks all that makes a lot of sense. Now I tried using the R4CCE to edit and the codes didn't work on the rom-hacked NSMB. However, my question about Must Be On codes have been answered, thank you!!! This is a wonderful community.

glad that you think like this ...
someone on the other hand just bombarded me and said....
you only help the popular

if the codes didn't work then you might need to hack it

its not new that a patched/hacked rom might changes the original address
since you said you could code then it should not be much problem for you to redo the work
