Troubleshooting

Q: I tried to apply a patch, but it comes up with an error "Checksums do not match".
A: There are two possible places this can occur - while doing a checksum on the patch file or while doing a checksum on a maplestory file. If, by looking at the command prompt window, you can see that it hasn't tried patching any files yet, you can assume that the checksum failed for the patch file itself. Redownload the patch file, and try using a download manager. If the checksum fails on a specific file, then you either have the wrong patch file (redownload the correct one) or the wrong version of Maplestory (redownload Maplestory). Try using the version command to ensure you are using the correct version with the correct patch.

Q: I tried using read/write/split commands, but the command prompt open and closes.
A: Working as intended. NXPatcher shows no prompts or notifications that it has completed as this can be annoying for people creating multiple pre-patchers. Look in the same directory as NXPatcher for the EXE representing the patch file. For example, if your patch file is named "Weasels.patch", look for the "Weasels.exe" file.

Q: I get an error "Out of memory reallocation!"
A: This means NXPatcher ran out of memory in RAM. Open NXPatcher.ini. In the [read] section, change "usefastpatchtype" to 0. Try running the program again. If you run into the same error, then, in the [hijack] section, change "usefastpatchtype" to 0.

Q: The program won't work and I can't find a solution in this troubleshooting section.
A: Create an Issue in this github. I'll see it.
