Split Personalities Plus Keyboard Patch

[Maniac]

Just reading the Retro Gamer 191 (yes I know I'm many issues behind!) article on Split Personalities. I loved this game on my 464 but when I got my 6128 plus in 1990 I was gutted I couldn't play it as it suffered from the keyboard issues some games had. Does anybody know if this game has been patched for this please as I'm struggling to find it if it has?
