getting started / prerequisites

you will need a linux environment (wsl, mingw...) with ruby and make

you will also need the macroassembler as providing asl. get mas from the AUR or download and build:

wget http://john.ccac.rwth-aachen.de:8000/ftp/as/source/c_version/asl-current-142-bld213.tar.bz2
tar -xf asl-current-142-bld213.tar.gz
cd asl-current
# copy appropriate makefile.def, e.g.:
cp Makefile.def-samples/Makefile.def-unknown-linux Makefile.def
make
make install

usage / applying assembly patches

NOTE: make sure original roms landmakr.zip and landmakrj.zip are in the roms/ folder.

run make in any patch subfolder
patched files will be in out/

additional make targets:

• make ips :: create ips patch files (requires cmdpack-uips)
• make landmakr :: Land Maker 2.02O-only target
• make landmakrj :: Land Maker 2.01J-only target

the steps for patching are:

1. interleave source files into program binary
2. assemble patch.S over original program using asl
3. generate patched program binary from object file with p2bin
4. deinterleave patched binary into original rom files
5. package up new files, create ips patches

development / how to make a patch

1. copy example/ template with assembler source and makefile
2. write patch
3. make landmakr or make landmakrj

to make patches compatible with both rom versions, include the shift table: shifts.S

for every ROM address referenced, add the closest SHIFT constant less than the desired address. for example:

	ORG $8EC70 + SHIFT_15FBC
	ORG $93BF4 + SHIFT_91470
	ORG $1FFFFE + SHIFT_A1416
