Can`t recall that I have ever seen that before - next level SNK Engrish or some bug?
- Latest stable NG core
- CHD Samurai Spirits ~ Samurai Shodown (Japan) (En,Ja).chd (MD5 = a671fdf36d27f7873d4b962fd374989c)
- Unibios set to Toploader, EN or US Region
- Start the game & watch the demo
Spelling is correct (´purpose´) in the cartridge-variant.
EDIT: Found a clip on YT showing the same issue https://www.youtube.com/watch?v=UyxOO9jnuak
