An old idea for a new project..

2007-04-22T09:10:00.000+02:00

yesterday, when i was having a shower, i had some brilliant ideas to recycle the famous television game: "who wants to be a milionare" and port it to ds.
The project will be called: WWTBAFM and the extra F stands for "fake" because no money will be earn by players :)

these are the specifications for the game i'll develop in next months:
- DLDI support for external file (that will content questions and language files)
- Cute gfx totally inspired by the television program
- Sound Effect
- Maybe some music theme?! (not confirmed)
- Maybe some gfx effects (alpha/zoom).
- Maybe Internet Automatic Updates
- And last, because i don't know if i can do it, voice recognition in one aspect of the game.

Yours ideas and opinions will be taken in consideration

Chiip Programmer

2007-03-04T13:42:00.000+01:00

Yesterday night i did the chiip programmer:

if you don't know how to cut the plastic, just use a red-hot knife
use thin wires. but not too much thin! (mine wires were too much thin. very difficult to solder in that small space)
study (before soldering) the components positions. remember that you'll have to close that box!
if you're socket's pins are too short, solder wires to pins and then pass the wires inside the box

Well, now i just need one or two atmega8L8.. but i can't find it in Rome.. if you want to help me, buy 1 or 2 atmega8L8 and send them to me. i'll pay you for chips/shipping/time :)

Here some photos.

Homemade Wii SensorBar 3

2007-01-23T21:32:00.000+01:00

well, it's finished! it's a "tri-slot" extensible sensorbar, with a switch and a power indicator.

Homemade Wii SensorBar 2

2007-01-19T08:24:00.000+01:00

i found my gpu fan burned on sundey and only yesterday i could buy a new one.. well.. i haven't do the sensorbar because i missed some component and i lost my car on a car accident 1 week ago..

now i've got all. maybe tomorrow i'll start to do it. here a photo about the circuit that i'm going to solder.

Homemade Wii SensorBar 1

2007-01-12T22:15:00.000+01:00

Here is the circuit..
and those are the specifications..
Resistor: from 70 to 82 ohm (i found 82 ohm)
infrared led: 1.3-1.8V & 10-20mA
USB: 5V

well, i did it and it's working well.. and i discovered that i bought 2 burned out led on 4.. :\

tomorrow i'll go to buy some new led and i'll start to craft a better bar.

everything will be documented :)

Homemade Wii SensorBar 0

2007-01-10T23:32:00.000+01:00

hello guys! i went to 15 shops to search the wii and i didn't find one! :\ now i booked one on the net.. i think that i have to wait a month..

well but i'm also building my own sensorbar for play on pc with my wiimote! (i found the last wiiplay XD)

The House of the Dead is the ideal title!
and now some images about the WIP lotti's sensorbar

MancalaDS v2.0: sound bug (fixed)

2007-01-08T07:55:00.000+01:00

some of you, probably, have noticed the sound bug that was afflicting the 2.0 version of MancalaDS.. well it was fault of the ancient makefile that i was using.. now i changed it and i recompiled all.. happy download to all!

mancalaDS v2.0 as christmas gift

2006-12-23T23:00:00.000+01:00

well, i'm waiting for HtheB's theme song for the last version of mancalaDS.. but i don't know when he will give it to me and i'm leaving home on 26th of december.. so i publish the latest version of mancalaDS and i hope to upgrade it with theme song the next year :) merry christmas and happy new year to all :)

P.S.: i just want to remember how you can help me to improve this new version:
-----------------------
Send me sounds that are in the game (but without noise, high quality). mp3/wav/raw doesn't make differences.

about MancalaDS v2.0 indiscretions

2006-12-21T19:58:00.000+01:00

UPDATE: HtheB will do the theme song for my game.

hello guys.. mancalaDS v2.0 it's almost complete.. i need only a theme song.. however, let's see the improvements:

-Sprites Changed
-Added Animations (pretty cool)
-Added Sounds (mmm i haven't found them on the net.. so i have to capture them plugging cable form line out to line in :\. infact they have a bit of noise)
-Everything is Mario's Style, now.

How you can help me? Oh it's simple! just send me sounds that are in the game (but without noise, high quality). mp3/wav/raw doesn't make differences.

Video: boost up the volume

and now belongs to us! (MancalaDS v1.5 out!)

2006-12-16T23:25:00.000+01:00

UPDATE 20061218 - 21.18
the "i'm not going to switch the screens, so you'll got the menu all missed up" is now fixed. please redownload the game/sources. Thanks to ozroc for the report!

UPDATE 2.54am
i fixed some little graphic things and added some keys functionality. i think now it's the true final v1.5.
-----------------------------
Soooooo.. finally it's done! wow, i made my first automata!
i'm enough tired, but it's finished for now (do you remember? i promised new gfx..). now it has a skilled AI (easy and normal) so now you can play solo mode. another interesting function it's the "watch a game" mode.. pretty useless, but i put it in for people that like to watch their nds while is playing alone (i'm one of them).

what else? oh well, the ai levels.
easy: ai first try to do the best capture move and if it isn't available, do a random move
normal: ai first try to do a perfect move, then try the best capture move and if they aren't available, do a random move
hard: i haven't coded an hard level, beacuse it's not so simple and maybe i'm missing knowledges and i don't feel like doing it now.

i didn't test it very well because i'm tired. i hope you will find bugs or improvements and then report them to me for a fix. i'll fix them, promise :)

here it comes the download links.

MancalaDS 1.5 nearly done

2006-12-16T03:25:00.000+01:00

another night has nearly gone and mancalaDS it's growing very fast.
This night i added the possibility to choose how many beans to start with. it was a gbarl user suggestion, at this time i can't remember who asked for it. I predispose the game structure to fit the singleplayer game too. All it's ready and working.. what it misses? the AI.. i think i could develop it well after some nice hours of sleep.

hey guys! take a look to tagDS it's a very nice 2player game made by tassu. [download here]

MancalaDS v1.0 out!

2006-12-15T20:28:00.000+01:00

so, i solved the weird bug that was afflicting a sprite. the solution? it was setted to 16colors on pagfx.ini when it needed to be 256colors.. very weird bug.

now it works well and i'm ready to publish it. just take it :)
MancalaDS v1.0

New nds games for Christmas

2006-12-15T02:42:00.000+01:00

hello guys.. i'm developing 2 new little games for nds..
first: MancalaDS
second: ShowMeTheMoney.

MancalaDS
---------
First, what the fuck is Mancala? Mancala is an ancient game played by Egyptians. It has many names like Bantumi, Kalah, etc.. It appears also on the legendary (and ancient) Nokia 3310 as a game. I fallen in love with this game when my father bought that mobile phone.
MancalaDS it's finished, i have to solve just a bug on 2 sprites, but it's done! the version 1.0 will be out today for sure (maybe not before 10-12 hours.. i need to sleep!)
The good thing is that MancalaDS is a very nice and simple strategic game and this version it's for 2 player on the same nds.
Another good thing it's that i'm planning to do an AI for this game.
Another (and last) good thing about this game is that i planned to use a better gfx but it's still in development (cool effects need more time to be coded).
So i can show you a screen of this MancalaDS.. it's on the right side of this post.
That's all for MancalaDS. for now.

ShowMeTheMoney
--------------
This second game it's an adaptation to nds of the american tv show "Show Me The Money"/italian show "Tutto per Tutto". This is not an ability game. It's all fortune based. here, you can read the plot of "Show Me The Money" show, so you can figure out what this game is.
The engine of this game it's done, but i need to craft a lot of missing graphic/sprites. Two people said "we'll give you a hand with gfx and sound effects" (those are Dexther (sound) and krad (graphic) on gbarl) a week ago, but i didn't see anything till today. I think that if they wouldn't help me, i'll put this game on "pause" until MancalaDS is finished.

So, that's all for tonight. i'm very tired. see you around and feel free to reply whatever you want. bye.

LiteDat (the dat manager in action!)

or you can see how it works here

Dat Manager is out!

2006-11-04T23:30:00.000+01:00

today i wrote a dat manager (for nintendo ds, compatible with offline list) that works with php and mysql (only 1 table). it's pretty basic but it works well. it uses smarty (as template manager). if you want to take a look to it or just take a copy of source code to build your own nintendo ds dat file, simple ask me about it.

improving the md5 encryption!

2006-10-11T16:27:00.000+02:00

hello guys :) today i studied a very simple method to improve the md5 protection against all available vocabulary attacks that are popping out in these months.
it's very simple. it consists of add 2 or more md5 hash (for example, the password plus username plus date of registration) char by char.

now we got a new hash string that doesn't appears like a normal hash (isn't hexadecimal). so what we need to do now? simple! just re-encrypt this strange hash.

now we got particular hash that can't return in any way the username nor password nor date of registration.

here's the sample code:
--------------------------

<form method="post">
username: <input name="username"> <br>
password: <input name="password"><br>
<input name="data"><br>
<br>
<?
$username=$_POST["username"];
$password=$_POST["password"];
$data=$_POST["data"];
$sum="";

$md5username=md5($username);
$md5password=md5($password);
$md5data=md5($data);

for($i=0;$i<32;$i++)
$sum.=chr(ord($md5username[$i])+ord($md5password[$i])+ord($md5data[$i]));

$hash=md5($sum);

echo "hash di ".$username.": ".$md5username."<br>";
echo "hash di ".$password.": ".$md5password."<br>";
echo "hash di ".$data.": ".$md5data."<br>";
echo "somma degli hash: ".$sum."<br>";
echo "hash della somma: ".$hash."<br>";

?>
<br>
<br>
LOGIN <br>
username: <input name="l1"> <br>
password: <input name="l2"><br>
<input name="l3"><br>
<input type="submit"><br>
</form>

<?

$l1=$_POST["l1"];
$l2=$_POST["l2"];
$l3=$_POST["l3"];
$l4="";

$md5l1=md5($l1);
$md5l2=md5($l2);
$md5l3=md5($l3);

for($i=0;$i<32;$i++)
$l4.=chr(ord($md5l1[$i])+ord($md5l2[$i])+ord($md5l3[$i]));

$hashl4=md5($l4);

if ($hashl4==$hash) echo "login succesful";
else echo "login denied";

?>
