Atari 7800 Multicart

 

Version: 30/09/2014

A long time ago, I have created a Multicart for the Colecovision.

Now, it is time to do the same for a very nice console : Atari 7800 console.

For the moment, only a prototype has been made and I am still debugging it. I will post the full package when all bugs are fixed.

Keep in touch !

Tombstone City for NDS

 

Version:18 July 2011

Warning : The music is pretty lound & noisy. I need to understand why ...

 

What's that

Tombstone city is a game developped in 1981 by Texas Instrusment for the TI99/A4. (see [http://www.videogamehouse.net/tombstone.html] or [http://en.wikipedia.org/wiki/Tombstone_City:_21st_Century]).

This game corresponds to my own implementation of the original game, ready to run on a Nintendo NDS.

The main used tools are:

• libnds
• devkitARM
• PAlib-070717

What's new

Now integrates music and sounds.

Installation

To be able to run this homebrew, you need a linker such as R4, M3, ...

So, copy the TombstoneDS/bin/TombstoneDS.nds binary somewhere in its memory card and run it !

Keys

• X or A : Fire
• Arrows : Move
• R or L : Panic button. Put the player on a safety place but score is cleared !
• Select : Restart the game
• Start : Pause / Continue

The attached package contains source code and the binary.

Enjoy !
