Tools and utilities for modifying SF2 Cabinets

What

This repository contains research and tooling around the mini Street Fighter 2 cabinet releasd late last year

Current capabilties include:

SPI flash extraction via the sunxi-fel utilities
- Note You can also do this in circuit with a SOP8 clip and flashrom, but it's obviously much easier to do this via the FEL loader
Startup script modification via the scripts listed below
MINFS partition parsing, allowing for a full extraction of all availalble files

scripts: Bash scripts for extracting filesystem components / reflashing the cabinet via the FEL loader.
- Note: There is a lot of development code in here
python: Assorted python scripts to extract files based on the autogenerated Kaitai classes, as well as my original implementation of the MinFS parser in python
binary-templates: A collection of kaitai and 010Editor templates for use with the entire SPI flash image as well as standalone MinFS filesystem images
logs: Logfiles generated by modifying the startup.esh script that is launched by the cabinet on startup. This contains a directory listing as well as other debug output about the boot and loading process.

While some files can be viewed normally, others are compressed with some variation of LZMA
- While we can extract some of these manually, this process could and should be automated
Decompression of the executable files
- These are similarly compressed with some form of LZMA, but do not compress as easily as the bitmap files
Document and write up example of extracting and decompressing the splash screen on boot
