Any comments are most welcome!

New version uploaded!
It has that annoying hiscore bug fixed, appart from other minor improvements, like mouse wheel control.

Er, what's the cheat code for the original remake?

And am I correct in believing that the "x4" of this version refers to the graphic cells being 16x16 rather than the 8x8 of the original, so that they're 4x larger (in area) than before?

Hi, and excuse me becouse of the late answer, I know I don't come arround here as often as I should...

Well, it¡s been five years since it was released, so I think I can tell you: just type the word "mortadelo" when playing the game, and a new button will appear
And no, it doesn't work on the x4 version

[right][snapback]1916[/snapback][/right]

Your'e nearly right Original Speccy tiles where 16x16 and this remake's are 64x64. In fact, the Spectrum's screen resolution was 256x192, and this new remake is 1024x768, hence the x4 on the title

The source code from http://retrospec.sgn.net/users/ignacio/dow...lektor_x4_f.zip is the last available?
When trying to play in Linux I found that the buttons from the main menu had no text. After debugging...

- dlg_inicializar() doesn't specifies a default value for "boton.dialogo".
- dlg_incorporar_boton() makes the next test:
CODE
for(f=num_boton=0;f<NUM_BOTONES && boton[f].dialogo>=0;f++)
if(boton[f].dialogo==dialogo) num_boton++;

the test is correct... if default boton[f].dialogo != 0. Since you don't specify a default value the compiler specifies it, and '0' is value a lot of compliers would use. gcc does, and so the buttons from te main menu have no text.

But even if I add a "boton[f].dialogo = -1" to dlg_inicializar() the buttons still appear without text.
The problem is
CODE
for(f=0;f<NUM_BOTONES;f++)
{
tipo_fuente[f].fuente=NULL;
tipo_fuente[f].dy_fuente=0;
}

inside dlg_inicializar().
It should be:
CODE
for(f=0;f<NUM_FUENTES;f++)
{
tipo_fuente[f].fuente=NULL;
tipo_fuente[f].dy_fuente=0;
}

NUM_BOTONES must be replaced by NUM_FUENTES.
Since NUM_BOTONES > NUM_FUENTES the original code overwrites the array boton[] in the code generated by gcc.

I was thinking about packaging the game for Linux. But is this source the last one available? I can't even believe your compiler generated a working code from this source... that would be a lot of luck.

I have wrote the missing code that adds support for sending highscore for Linux (or any other OS with libcurl support...). But then I found this in introducir_puntuacion() from deflektor.c
CODE
if(f)
{int pntt;
char cd[21];
for(;f<28;nombre[f++]=' ');
for(f=27,pntt=puntuacion; f>21 && pntt; f--,pntt/=10) nombre[f]='0'+pntt%10;
for(f=0;f<21;cd[f++]=0);
for(f=8;f>i;f--)
{// Desplazamos hacia abajo los récords menores
for(n=0;n<28;n++) max_txt[f*29+n]=max_txt[(f-1)*29+n];
max_pnt[f]=max_pnt[f-1];
for(n=0;n<12;n++) max_cod[f*13+n]=max_cod[(f-1)*13+n];
}
for(f=0;f<28;f++) max_txt[i*29+f]=nombre[f];
max_pnt[i]=puntuacion;
for(f=0;f<12;f++) max_cod[i*13+f]=cd[f];
escribir_pnt();
puntuaciones(10+i);
}

These two lines
CODE
for(f=0;f<21;cd[f++]=0);
for(f=0;f<12;f++) max_cod[i*13+f]=cd[f];

ensure that max_cod[] will be all zero. And since max_cod is the part that stores the score that is send to the server, the score is never added to the website.

Is this some kind of proteccion against cheats or the source code available for download is really an old version?

In any case, here there is a patch that corrects the bugs and adds Internet highscore support to Linux:

Since the code tries to look like the windows version (looking for a future merge) it can be considered a derived work under the same licence that the rest of the game. But if someone is going to release binaries that link statically against libcurl remember that it is MIT lincensed, and so it requires the original license to be distributed with the game.

Hi there!

Yes it does
Just look at the first for instruction, where it says:
CODE
boton[f].estado=boton[f].dialogo=boton[f].numero=-1;

QUOTE(RedDwarf @ Feb 2 2008, 11:40 PM)
The problem is
CODE

for(f=0;f<NUM_BOTONES;f++)
{
tipo_fuente[f].fuente=NULL;

inside dlg_inicializar().
It should be:
CODE

for(f=0;f<NUM_FUENTES;f++)
{
tipo_fuente[f].fuente=NULL;
tipo_fuente[f].dy_fuente=0;
}

NUM_BOTONES must be replaced by NUM_FUENTES.
Now your'e dead right there! Of course it should be NUM_FUENTES!
I've done a few tests to see why it's not causing any apparent problems on the Windows version, and all I've seen is the code generated by my compiler is not overwriting the botones array. The compiler only knows wtf is it overwriting then, but it must not be any important stuff, as it works just fine despite of such an ugly bug
I could investigate it a bit more, but I'm just too busy right now, so I'll just upload a fixed version when I have the time and forget about it. And of course, you'll be credited for such a bug hunt; you can even hang it's head over the chimney if you want

The code that generates the hiscore code being sent has been deliberately censored to avoid cheating. Otherwise, anyone could compile it to get any fake score uploaded, spoiling all the fun on it

Well, thanks again for spotting that bug!

Just a line before I saw a '0' in the debugger (probably because the NUM_FUENTES) and so seems I not searched very deeply :-p
Well, so isn't so unincredible that the compiler generated working code after all.

So can you add the Linux/curl code to your (complete) Linux build? So Linux users can also upload their highscores. I verified with Wireshark that it sent the correct URL (but with the missing code). The server doesn't requires any specific User-Agent, HTTP version or so to accept the scores, true? Just any GET petition with the correct URL and code?

hello,
whenever we port games it's usually done by people we know, or if the person doing the conversion seems honest enough we give them the code but ask them not to show anyone the highscore code.

as such, any source code release we do for games we always exclude the hs stuff.

if you want to do a conversion and will honour this high-score code them I'm sure we can let you have it.

If you need someone to create the static builds that are hosted here sure, give me the code and I will build it. But you have here the patch with the missing code needed for Linux, if you have a Linux box available you can create it yourself without trusting noone else (i.e. me ;-) ).
When publishing distribution specific packages in the openSUSE Build Service the source code is also published. So these packages can't have upload support anyway.

Any sign of the Mac port that RetroSpec says there is?

Done!
You can already get the Mac port from the website :)
