I've seen a trailer of another fighting game The Rumble Fish Plus that has character move-lists displayed on the screen borders. Experiments with the KoF98/02 files, I've found that:
- Editing the "strings.txt" file in [Data] changes the values of the Command List
- Editing the bg2.png in [Data->game] changes the border art (keeping the dimensions leaves the image split)
- The QQ version has the command list (only for a single player).
Keep up the great work as always
