Here you have the Preston version of Hungry Horace, tested on XRoar and my loyal Dragon 64.
I created the wiki page for it (here), and as I thought it would be a bit dumb to have two different pages for the Melbourne House and the Preston versions, I left some room there to add the scans or pictures of the Melbourne House version.
The only thing I couldn't find is the year Preston published the game, it isn't anywhere to find!
Have a nice weekend!
