Rewrote the Truco-Tron driver. [Roberto Fresca, Grull Osgo]
- Added real NVRAM support. - Added a default NVRAM to get the system working. - Improve the memory system. - Inputs from the scratch based on the new reverse-engineering. - Added jumpers connections. - Created settings for the hardcoded functions/modes. - Added coin-in and coin-out counters. - Added workaround to unmask the inputs for the gambling mode. - Redefined the interrupt system. - Documented all the different modes and features. - Documented the reverse-ingeneering done to get all the modes working. - Documented the inut system through reverse-engineering. - Modded the coin-in input, now tied to the PIA6821.

Notes:
|
||||
*****************************************************************************************************************
|
||||
|
||||
- The board uses a battery backed ram for protection, mapped at $7c00-$7fff.
|
||||
- If the battery backup data is corrupt, it comes up with some sort of code entry screen.
|
||||
- The game stores the current credits count in the battery backed ram.
|
||||
- System clock is 12 Mhz. The CPU clock is unknown.
|
||||
- The Alternate GFX mode is funky. Not only it has different bitmaps, but also the strings with the
|
||||
game options are truncated. Title is also truncated.
|
||||
- At least one bootleg board exist.
|
||||
This appears to be the first arcade game fully designed in Argentina. The hardware, which is based on a M6809E CPU,
|
||||
is unlike anything previously known.
|
||||
|
||||
*******************************************************************************************************
|
||||
The game is based on Truco, a traditional and highly strategic Argentine card game. It's known for being difficult
|
||||
to play, as the objective is to earn points by playing cards while bluffing about the hand you hold.
|
||||
|
||||
For more about the rules of Truco, see the following links:
|
||||
https://www.nhfournier.es/en/como-jugar/truco/
|
||||
https://www.wikihow.com/Play-Truco
|
||||
|
||||
|
||||
Truco-tron focuses on the "1 player vs machine" mode (mano a mano), offering a unique arcade experience.
|
||||
|
||||
All game and technical information, including the emulation and IC's recognition, was obtained
|
||||
by reverse-engineering both the hardware and game code.
|
||||
|
||||
The game has various settings hardcoded into non-volatile RAM, which are inaccessible to the user.
|
||||
The entire RAM system is powered by a 3.6V lithium battery, which is monitored by a Maxim MAX691 device.
|
||||
If power is lost or the battery drains, the game becomes inoperable and requires a fresh RAM image to function again.
|
||||
|
||||
If the RAM contents are missing, a yellow password entry screen appears, but it serves no purpose. It’s believed that
|
||||
the original design intended to show a repair screen, as the necessary values are hardcoded and ready to be injected.
|
||||
However, the game code attempts to inject incorrect values, which results in garbage data and prevents the game from
|
||||
booting properly.
|
||||
|
||||
In normal arcade mode, defeating the machine rewards the player with a free game.
|
||||
|
||||
Though marketed as an arcade game, Truco-tron also contains a hidden gambling mode that is inaccessible by default.
|
||||
Enabling this mode requires substantial modifications, such as adding extra inputs and altering the PIA 6821 inputs
|
||||
mask that hides them. Once activated, a supervisor key appears, providing two new inputs for adding and removing credits,
|
||||
functioning as key-in and key-out.
|
||||
|
||||
The gambling mode features a selectable risk level, allowing players to multiply their winnings but at the cost of
|
||||
increasing the amount of credits at risk.
|
||||
|
||||
Another hidden mode, likely used during development for debugging, enables the player to set their cards in the game,
|
||||
allowing for a more controlled test environment.
|
||||
|
||||
|
||||
How to Activate Gambling Mode
|
||||
-----------------------------
|
||||
|
||||
Go to the machine's configuration menu and select the gambling game mode.
|
||||
Introduce one credit, and then press the button to enter the credits screen.
|
||||
Turn the supervisor key (hold the SERVICE button), and you can add credits using the standard coin mechanism
|
||||
or the key-in button (Key Q). Use the joystick and game button to select the desired risk level.
|
||||
To collect credits, use the TILT button as key-out (Key T).
|
||||
|
||||
You can also press the BOOKS button to view the in/out counters on the credits screen.
|
||||
There are jumpers, but they are just holes instead of actual jumpers. It seems they never anticipated a real
|
||||
implementation. The effects and settings are visible below.
|
||||
|
||||
|
||||
Easter Egg
|
||||
----------
|
||||
|
||||
Hidden within the game is an encrypted message, which appears after a specific combination of inputs is entered.
|
||||
This can only be triggered when you have 8 credits in gambling mode and have lied about Flor.
|
||||
|
||||
The hidden message reads:
|
||||
"ESTE PROGRAMA DE JUEGO DE TRUCO PERTENECE A LOS PROPIETARIOS DE LA MARCA LANZA PERFUME"
|
||||
|
||||
Reaching this message is incredibly complex, and if the wrong action is taken, a small red dot will appear,
|
||||
causing the game to "suicide" itself. This will require the RAM contents to be reloaded in order for the game
|
||||
to work again.
|
||||
|
||||
|
||||
Additionally, the game features an unfinished alternate graphics mode with clipped strings, which can be switched
|
||||
on using one of the jumpers.
|
||||
|
||||
It is believed that only 300 of these boards were ever produced.
