/**********************************************************************************
Le Pendu.
Avenir Amusement Inc.
Very rare French/English bilingual hangman style game.
Sequel of "Le Super Pendu", with better graphics among other things...
Runs in a heavily modified Bonanza Enterprises hardware.
Driver by Roberto Fresca & Grull Osgo.
***********************************************************************************
The "mini-boy" poker games made by Bonanza Enterprises were very popular
in Quebec back in the early '80s. They were everywhere in small restaurants,
bars and convenience stores.
Popularity faded away when the slot machines (lucky 7's) were introduced.
Many "miniboy" machines were converted to play lucky 7 slots. (A kit was
available from a local company).
All independent gambling devices were made illegal in 1993, when the government
lottery company (lotto-Quebec) took over the video-lottery business. Thousands
of machines were stored, destroyed or seized by the police.
To keep them alive, some of these machines were converted to Le Pendu / Hangman.
A conversion kit was proposed by a local company, developed in Quebec.
The kit includes a in-house modification of the "Bonanza" poker board, plus a new
5 buttons plate to replace the traditional 15 poker buttons, since the game has
nothing to do with gambling (Hangman game, you need to guess a word before the
character man is hanged).
It was not a great success, so the game is very rare. On top of that, the designer
added copy protection to his work, and the game cannot start when the battery
drains. (part of the modification was to remove the battery memory on/off switch)
There are some critical registers and rerouted subroutines in the battery backed
RAM, hence the game dies once the battery drains.
Here, you can see a video of the game working for refference:
