Usage
A pre-built image is available on Docker Hub.
# convert iidx 25, 26, 27 & 28 patches
docker run --rm -it -u $(id -u):$(id -g) -v $(pwd):/data aixxe/b2mpatch b2mpatch.js \
--dir=/data/bin/2018091900 --url=https://github.com/mon/BemaniPatcher/raw/master/ballerz.html \
--dir=/data/bin/2019090200 --url=https://github.com/mon/BemaniPatcher/raw/master/rootage.html \
--dir=/data/bin/2020092900 --url=https://github.com/mon/BemaniPatcher/raw/master/heroicverse.html \
--dir=/data/bin/2021091500 --url=https://github.com/mon/BemaniPatcher/raw/master/bistrover.html \
--output=/data/patches/
A pair of --dir and --url arguments must be provided for each patcher.
- The
--dirargument should contain all executable files required by the patcher. - The
--urlargument should contain a full URL to a patcher page.
If the --output option is not defined, all converted files will be saved to the current directory.
All patches are disabled by default.
To enable a patch, remove the # prefix from the line containing the offset and bytes.
# Disabled patch
# example.exe 7E6B5 909090 33C055
# Enabled patch
example.exe CF683 9090 4DA8
Options for union-type patches are denoted by a ## prefix. Only one should be enabled at a time.
# Patch with multiple options
## Option 1 (disabled)
# example.exe 447A0B 45540F94C0 4AD3FF80F8
## Option 2 (enabled)
example.exe 447A0B 4584ED750E 4AD3FF80F8
## Option 3 (disabled)
# example.exe 447A0B 40488B00FF 4AD3FF80F8
Additionally, diff2patch.js can be used to generate a mempatch file from two binaries.
# generate omnimix patch using the original and modified binaries
docker run --rm -it -u $(id -u):$(id -g) -v $(pwd):/data aixxe/b2mpatch diff2patch.js \
