vbt & slinga : great job !

Could you please post your code ?

 slinga May 12, 2003
Don't thank me, it's all VBT's hard work. From what I saw he has the boot menu working perfectly on GiriGiri, it doesn't seem to work properly on a real saturn though.

 vbt Jun 21, 2003
I've exploded the boot loader here is the pic viewer alone : Pic Viewer...

I'll release it only if I manage to make it working fully or partially, I improved my code but it still doesn't work correctly.

 mrkotfw Jun 22, 2003
hey maybe we can help if you release the code

 vbt Jun 23, 2003
It seems now it works both on ssf and girigi but only if I don't use gfx or text display I 'll try to burn a CD to see the result.

I use that code to display simple text :

Code: 
  
#ifdef SBL_VBT

  SCL_Vdp2Init();

  SetVblank();

  set_imask(0);

  SCL_SetPriority(SCL_SP0|SCL_SP1|SCL_SP2|SCL_SP3|

          SCL_SP4|SCL_SP5|SCL_SP6|SCL_SP7,6);

  SCL_SetSpriteMode(SCL_TYPE1,SCL_MIX,SCL_SP_WINDOW);

	

	SCL_SetFrameInterval( 1 );

	DBG_Initial( &dummy_pad, RGB16_COLOR(31,31,31), 0 );

	DBG_DisplayOn();

	// fonctionne :)

 i = 0;

	while(i < 200)

	{

 SCL_DisplayFrame();

 DBG_SetCursol(11, 12);

 DBG_Printf(" WAIT  ");

 i++;

	}

	DBG_DisplayOff();

#endif

nescphp, don't you have already SBL6 ? I worked on the sample gave with the SBL :

yes i now have it, i just found it on antime (you and the almighty antime saved me)

vbt please explain to me SBL (SEGA BASIC LIBRARY) the UPs and Downs, what i can do and what i cant do? thanks man.... i guess my demo can be better... WOOT... BTW, are you entering the contest?

yay i found it, after editing this post like 4 times

I could but I have nothing to show, I updated for instance my bootloader with no calls of SGL, no workarea.o, sl.lnk without sl_start etc ... but nothing interesting to show. I will update my functions on SMS emu. And now search a little how to configure GNUSH to make Saturn code. I found nothing on SX Normally there was a help from Takashi but I can't find it.

 mrkotfw Jun 25, 2003
oh, well could you maybe help me on trying to get SBL to work? it looks really great (the code) and i think i can do better... im trying to do this:

Code: 
  
 -display 0.bin

 -user presses start

 -loading menu.bin

 -display menu.bin

 -user presses a

 -loading game.bin

 -display game.bin

i think the GFS functions can do that but i cant compile because of the strt_1_g.o i think.

I've made some progress and I managed to display texts on SSF and Girigiri before booting my prog or games I'll add pad management and maybe a background and then burn a CD.

 slinga Jun 26, 2003
Seems like you've almost got it. If you can get pad management to work, it'll only be a few more lines of code before you can have a bootloader (just make some sorta user inputted selection.) Sorry for not being able to help, I'm having way to much fun at work (no I'm serious :cheers ).

 vbt Jun 28, 2003
Added pad working management using SBL6, it works perfectly on Girigiri but now it crashes on SSF after selecting a game. nverming I burn a CD, I'll see the result on a real Saturn.

 vbt Jun 28, 2003
IT WORKS

:cheers :devil :agree

 slinga Jun 28, 2003
Nice :cheers

Now try putting multiple programs on your disk (your pic viewer, sms emulator) and then have a user select which one from a menu. If that works, your my new hero.

 vbt Jun 28, 2003


It's not beautiful but it works, it uses only SBL, but I'll add my BG picture from my previous try soon.

results :

- Pic viewer works

- SMS menu works (I fogot to put the complete emu)

- GT24 works

- Outrun doesn't start but I think I've extracted uncorrectly the IP (didn't know where to cut the file)

- Final Romance R Bonus Disc start and displays the company logo but returns to the BIOS, I didn't know how to put CDDAs files

- Segra Rally I typed all files manually into my sl.cti and I think I've made some mistakes so It doesn't work, I had above the same problem on GT24 on my first tries, it started but textures were wrong and in fact I had mapped two differents files with the same file and cars textures were bad.

- game saves of GT24 are kept (I didn't verified that on real Saturn)

Pb :

- It doesn't return to my menu when I use A+B+C+START

 mrkotfw Jun 28, 2003
:cheers GREAT JOB! wow vbt

 vbt Jun 29, 2003
Here... is a small realease (8Mo), only button A, B and C can be used, I removed subfolders for other tests :

A - SMS simple menu (I'll put a working SMS emu next time)

B - GT24

C - pic viewer

I removed above all audio tracks, I don't know if it can cause problems on Saturn, this version with only one audio traack worked on Girigiri, also you can add all audio track s you want .
