Hello everyone. I'm in the process of editing a PC game that would have benefited from another round of proof-reading (E.g. Line overflows and typos in the main story-line, tutorial graphics that contradict the text, clear copy & paste mishaps, etc). This consists of using janky, Japanese-only tools to unpack files, convert the extracted files into editable formats using more black-box tools, make the changes and then do everything in reverse. Not difficult, but also not the most user-friendly workflow.
Ideally, I'd like to release my work as an executable auto-patcher, so that even casual Windows users can easily install and use it. However, I've never built one before, and I fear my initial idea of writing a wrapper that applies a byte-to-byte patch to 1.5GB package files is not the best solution.
Any conceptual advice on how to go about this would be appreciated. Thanks!
