Hey guys, been a while haha.
I'm trying to insert an ASM hack I found into the NSMB rom. I was able to do the simple binary cut and paste for other ASM's, but this ASM is different to the others, I think. I want to put this code into the game: https://nsmbhd.net/thread/3328-item-on-select/ hook_0211F844_ov_0A:
STMFD SP!, {R0, R1, LR}
LDR R0, =0x04000130
LDRB R0, [R0]
LSR R0, #2
ANDS R0, #1
LDMNEFD SP!, {R0, R1, PC}
LDR R0, =0x0208B698
LDR R1, =0x009500DA
STR R1, [R0]
LDR R1, =0x09600D40
STR R1, [R0, #0x8]
LDR R1, =0x1
STR R1, [R0, #0x4]
STR R1, [R0, #0xC]
LDMFD SP!, {R0, R1, PC} Luckily, I did find someone who was trying to do the same, but the explanation was very confusing for my tiny brain: https://gbatemp.net/threads/how-to-import-a-patch-for-nsmb.560609/ So could someone help me with some (very) basic instructions? I already have NSMBe v.356 and HxD installed, if that's important |

It is explained here: https://nsmbhd.net/thread/1281-how-asm-hacks-are-setup-tutorial/
What you got there is an ARM assembly source file. Save it in an file with the '.s' extension in the source folder and hit 'Run make and insert' _________________________ GitHub - Kuribo64 - YouTube |

Thanks for the help, but I think I ran into another problem
Doing those steps gets me this:  I installed DevkitPro already, so I'm not sure what the error is for. I tested it out using the ASM project template, but even using the default files (without the custom .s one) gave me an error anyway, Heres the full text: https://pastebin.com/aQm0eP6z

For the lgcc problem you should either remove lgcc from the makefile or follow RicBent's instructions on how to update your makefile https://nsmbhd.net/thread/3662-devkitpro-and-asm-help/#52113

I don't recommend removing lgcc because that can cause issues with certain code hacks, most notably skawo's fmv intro asm hack.

-lgcc missing is caused by devkitARM updating the gcc (the compiler) it uses.
See this commit https://github.com/Dirbaio/ASMPatchTemplate/commit/b6786d589a8237dce03aec66b88f89c363734084 It fixed the same issue 4 years ago. But gcc got updated several times since then again. The current version devkitARM uses is 10.1.0. You can always find out what version you got by looking into the devkitpro/devkitARM/lib/gcc/arm-none-eabi/ folder. There should be a single folder inside with the version of the install gcc. Just change the gcc version in the Makefile and you are good to go! Edit: I made a pull request to the patch template repo. Just have to wait for _________________________ GitHub - Kuribo64 - YouTube |
