Per the homepage:
"Here's my way to celebrate my 34th birthday: to release a new handheld simulator! This time it was more difficult than I thought, forcing me to "hack" the source code here and there - for this reason I'm not releasing it publicly, because it's not as "clean" as I wanted.
The game is also from the very nice VTech's "Tooth-Sporty" series (games with necklace). I'm also updating the previous game, Tennis Menace, which I released two weeks ago. Here's the list of news:

- Hot Line (VTech, Tooth-Sporty Time & Fun) S4/1.00 (Standard 4, final)
- Tennis Menace (VTech, Tooth-Sporty Time & Fun) S4/1.01 (Standard 4, more accuracy)


Grab the games and the new "CD Collection #47" from the downloads area and... happy birthday (to me!) :-P"
