I used to enjoy playing this game back when I was younger and I recently saw it on Steam and decided to play it again for old times sake. But sadly, there was a one slight problem with it. The game crashed whenever I clicked the play button. HOWEVER, THERE'S AN EASY WAY TO FIX THE CRASHING ISSUE!
1. Open C:\Program Files (x86)\Steam\SteamApps\common\Diner Dash Hometown Hero\assets\downloads\_default\restaurants on your computer and you will see a bunch of folders that should be called "ballpark", "boardwalk", "disco", "museum" and "zoo".
2. Go into all of those folders one by one and click on the folder inside each of them called "comics" and delete all the .swf files inside the "comics" folder that say "input" or "output".
3. If you did everything right, the game should work fine now (but be warned, the cutscenes won't be there anymore). Enjoy!
