Dingoo A320 forum

Fantastic alekmaul, thanks for the great speed-up news, and keep up the native software

I asked this before, but i will ask it again. Will you add load/save state to the emulators you provide in the future?

Thanks for all your efforts.

I've played around with the emulator and I have to say that I'm quite impressed. It's really good; the only problems I have with it are the same that other people have complained about: the sound, slowdown on certain games (but not all of them), and problems with sprite glitches in Space Harrier. Other than those, it's great. My only suggestion for version 1.1 of SMSGoo is that it have the ability to run Gamegear games fullscreen;

Great job, and good luck on your work on the PCE emulator.

Well, i don't think it's a good idea to rescale GG fullscreen, it will be too big.
Well, just a little wip :
- actually, sound volume can't be ajust so much but i don't know what to do, also i hear some little glitch but it not so important actually.
- text menu is ok (thanks to Mame4All font ^^)
- rescale algo is ok and fast, i'm happy
- Just have to add load/save state and i will release a new version for test.

Also it's SmsGGOO, not SMSGoo ! !

Thanks!

Looking forward for other stuff you can do for Dingoo!

Hey,

the stablility is really good!

Any chance you can take a fast and nice looking rescale algo(s)? Maybe from scummvm or dosbox, they have lots of it. Maybe that i can choose, which rescaler i want to use.

Any chance for zip support? That i can compress my rom as a zip, and call it for example "*.smsz" ?
You can checkout the zlib code here: svn://zwischenwelt.org:20684/dingoo/pie320/source

Just do:

gameengine.cpp

Code: Select all

#include "../zlib/unzip/unzip.h"
#define UNZIP_OK 0
#define UNZIP_ERROPEN 1
#define UNZIP_ERRNOTFOUND 2
#define UNZIP_ERRCREATE 3
#define UNZIP_ERRREAD 4
#define UNZIP_ERRWRITE 5

bool GameEngine::loadfromZipFile( const char * name, unsigned char * buf, int len, bool showErrorMsg = false )
{
   unzFile uf = 0;
   int result, bytes;
   char string[120];

   sprintf( string, "load file '%s' from zip!\n", name );
   LOG(_LS(string));

   uf = unzOpen( zipfile_path );
   if( !uf )
   {
      sprintf( string, "Cannot open file '%s' !\n", zipfile_path );
      LOG(_LS(string));
      return false;
   }

   LOG(_LS("unzLocateFile\n"));

   if( unzLocateFile( uf, name, 0 ) != UNZ_OK )
   {
      sprintf( string, "Can not find '%s' inside the zipfile !\n", name );
      LOG(_LS(string));
      unzCloseCurrentFile(uf);
      return false;
   }

   LOG(_LS("unzOpenCurrentFile\n"));

   if( unzOpenCurrentFile( uf) != UNZ_OK )
   {
      sprintf( string, "Can not open '%s' inside the zipfile !\n", name );
      LOG(_LS(string));
      unzCloseCurrentFile(uf);
      return false;
   }

   result = UNZIP_OK;

   LOG(_LS("unzReadCurrentFile\n"));

   bytes = unzReadCurrentFile( uf, buf, len );
   if( bytes < 0 )
   {
      sprintf( string, "Error reading %s %d!\n", name, bytes );
      LOG(_LS(string));
      return false;
   }

   LOG(_LS("unzCloseCurrentFile\n"));

   unzCloseCurrentFile( uf );

   LOG(_LS("End_UnzipFile=true\n"));
    return true;
}

//for example:
unsigned char   color[0x100];
loadfromZipFile( "filetoLoad.sms", color, sizeof(color), true)


gameengine.h

Code: Select all

public:
           bool   loadfromZipFile( const char * name, unsigned char * buf, int len, bool showErrorMsg );

//### data members:
public:
           char   *pac_rom_path;


Hi SiENcE,
As i said in the previous reply, the rescale engine is ok for me, fast and nice in my opinion.
About zip support, i don't know if it's really useful because sms games are small and only with one file.

Zipped 8-bit roms may actually end up being bigger, because of the header file, so no point in that....

ok.
