kylon / lipx Goto Github PK

Hello,
I would like to use your tool to patch a rom and it won't work.
Try this:
search and find this SNES rom: Chrono Trigger (US).smc
download the french translation patch from this site:
https://traf.romhack.org/?p=patchs&pid=1071&aff=coms

Try to patch the USA rom:
$ python ./lipx.py -a "SNES rom: Chrono Trigger (US).smc" "Chrono Trigger (Fr) v1.03.ips"
or
$ python3 ./lipx.py -a "SNES rom: Chrono Trigger (US).smc" "Chrono Trigger (Fr) v1.03.ips"
it won't work.

Thank you for your help.

Config: Ubuntu 18.04

Replacing static 'lipx.py' with dynamic will display help text that is consistent with the actual installed file (for example if installed as /usr/bin/lipx).

def usage():
    this = os.path.basename(sys.argv[0])
    print('\nLipx v' + VERSION + ' - Linux IPS tool\n\n' +
           'Usage:\n\n' +
           '    == Apply patch\n' +
           '    ' + this + ' -a originalFile patchFile\n\n' +
           '    == Create a copy and apply the patch - original is untouched\n' +
           '    ' + this + ' -ab originalFile patchFile [outputFile]\n\n' +
           '    == Create IPS patch\n' +
           '    ' + this + ' -c originalFile modifiedFile [outputFile]\n\n' +
           'Arguments:\n' +
           '    [] optional argument\n')

    sys.exit(1)

i noticed lipx currently doesnt create patches that truncate the patched file.
it appears many ips patching tools support a so-called "truncation/expansion extension", but i haven't found a specification so far.

Hi. I decided to learn some python to fix this issue.
Here's my patch.
Please test it well if you are considering using it. This was really my first python coding I've ever done.

Please add a license to this project so that users and developers are legally able to copy and contribute to it.

I recommend the COIL or the ISC license.

Steps to reproduce:

Download a Lunar ips patch
Apply the patch
Recreate the patch with Lipx

In some cases Lipx ips is bigger than the one from LunarIPS, although the game seems unaffected.
Needs more investigation.

The current shebang at the top of the script references python but this program requires Python 3. Most systems refer to Python 3.x as python3.
