Fullscreen SMS using SDL

I can't seem to find the sources for Yoshi's port of SMS.

So I started from scratch.

1. Download http://membres.lycos.fr/cyxdown/smssdl/ ... .1-src.zip

2. Create Makefile.psp

Code: Select all

TARGET = sms
PSPSDK=$&#40;shell psp-config --pspsdk-path&#41;
PSPBIN = $&#40;PSPSDK&#41;/../bin
SDL_CONFIG = $&#40;PSPBIN&#41;/sdl-config

OBJS   = main.o saves.o sdlsms.o filters.o \
            ../render.o ../sms.o ../system.o ../vdp.o \
            ../cpu/z80.o ../sound/emu2413.o ../sound/sn76496.o

INCDIR = 
CFLAGS = -O2 -G0 -Wall $&#40;shell $&#40;SDL_CONFIG&#41; --cflags&#41; \
        -I. -I.. -I../cpu -I../sound -DLSB_FIRST -DALIGN_DWORD
CXXFLAGS = $&#40;CFLAGS&#41; -fno-exceptions -fno-rtti -Wpointer-arith 
ASFLAGS = $&#40;CFLAGS&#41;

LIBDIR =
LDFLAGS = 
LIBS = $&#40;shell $&#40;SDL_CONFIG&#41; --libs&#41; 

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = SMS/SDL

include $&#40;PSPSDK&#41;/lib/build.mak

3. Overcome command line arguments and main=>SDL_main

Code: Select all

#ifndef PSP
int main&#40;int argc, char **argv&#41;
&#123;
#else
int SDL_main&#40;int argc, char **dummy_argv&#41;
&#123;
  const char *argv&#91;&#93; = &#123; "EBOOT.PBP", "rinco.gg", "--joystick", "--fullscreen", NULL &#125;;
  argc = 4;
#endif

4. build and install (and rename rom to rinco.gg)

So if someone can provide the Yoshi filebrowser, or make SDL_romselector.c... then that would be great.

to fix the sound, in sdlsms.c ...

Code: Select all

static void sdlsms_sound_update&#40;&#41;
&#123;
  int i;
  short* p;

#ifndef PSP
  SDL_LockAudio&#40;&#41;;
#endif
  p = &#40;short*&#41;sdl_sound.current_pos;
  for&#40;i = 0; i < snd.bufsize; ++i&#41; &#123;
      *p = snd.buffer&#91;0&#93;&#91;i&#93;;
      ++p;
      *p = snd.buffer&#91;1&#93;&#91;i&#93;;
      ++p;
  &#125;
  sdl_sound.current_pos = &#40;char*&#41;p;
  sdl_sound.current_emulated_samples += snd.bufsize * 2 * sizeof&#40;short&#41;;
#ifndef PSP
  SDL_UnlockAudio&#40;&#41;;
#endif
&#125;

looks like you have to hit the site twice to download, or go to http://membres.lycos.fr/cyxdown/smssdl/ and click on the latest src download.
