Sonic the Fighters: 2 Open Source Clones Compared

stfdecomp aims to produce buildable, labeled decompiled code for the arcade board Sonic the Fighters ran on, but the reverse engineering isn't complete — many addresses are still hardcoded without labels, and it's currently listed as unplayable. stfdisasm is further along: it's a complete disassembly that reassembles into a bit-perfect binary and is currently playable, though its build process is not yet 'shiftable' — custom code can only be inserted at the end of the ROM data.
