Saturn progamming

vbt - Nov 10, 2002

		Maybe you're right CyberWarriorX. I only see that it boots when I add an audio track, also I always burn CD as mixed mode data, it could explain that the saturn is looking for something more than one data track. I'm still looking for help to understand why the Saturn displays nothing on NBG1(slSynch could be misplaced ?). I hope somebody can find the solution. PS : here is the display cmd : slBMPut(-152, -138, 103, 53, bitmap_data);

Are you sure you are loading the complete data from the CD? SSF has faulty emulation of CD drive, so you might need to

increase the number of sectors read. reading your code:

>slScrPosNbg0(toFIXED(0.0), toFIXED(0.0));

>slScrPosNbg1(toFIXED(0.0), toFIXED(0.0));

>slScrAutoDisp(N
BG0ON|NBG1ON);

> slColRAMMode(CRM16_1024);

>slCharNbg1(COL_
TYPE_256,CHAR_SIZE_1
x1);

>slPlaneNbg1(PL_
SIZE_1x1);

>slMapNbg1((void*)NBG1_MAP_ADR,(void*) NBG1_MAP_ADR,(void*)NBG1_MAP_ADR,(void*)NBG1_MAP_ADR); I'd skip this line, if you're doing bitmap drawing.

>slBMPaletteNbg1
(1);

>slInitBitMap(bmNBG1, BM_512x256,(void *)NBG1_CEL_ADR);

>slZoomNbg1(toFIXED(0.86), toFIXED(0.86));

slScrAutoDisp(NBG0ON
|NBG1ON);

>slPlaneNbg1(PL_
SIZE_1x1);

>slTVOn();

slSynch();

...

This should do the trick.

		Thanks again for your help TakaIsSilly . The emu run again after your modifications on SSF and Satourne. Also I manage to finish the first level of R-Type without loosing a life I'll try soon to burn a CD to see if it works. This another picture of a running game (Robocod) :

		nice work guys keep on.... I'm having asm programming in the next months (in college) maybe I'll start reading sh2 asm...

		TakaIsSilly	Dec 10, 2002
		SH-2 is the 6805 of the RISC engines. Simple and cool to program for, but it won't get you a better grade in college. Belive me, I know ^^; vbt, you're progressing nicely. I don't know what base you are using, but if you're doing the continuation of work from Denis emulator, I have some code to help speed up the emulation, the tile optimizations I talked about earlier... I'll share it in a while, if I'm able to start a Saturn emulator in this 200MMX to check how far i went ^^;

		IBarracudaI	Dec 10, 2002
		I didnt mean learning SH2 asm, to help out my college studies, actually I meant the other way around, learning some more asm basics on college, and then start reading SH2 stuff. VBT, you should take your screenshots by pressing ALT + PRINTSCREEN , not just PRINTSCREEN, this way it will only take a screenshot at the active window... which means smaller files...

		vbt	Dec 10, 2002
		I know Asm too (68k, 8051 and 8086) but never practice after school , it could be interesting if you (IBarracudaI) manage to trnslate some 8086 code to sh2 it would be easier for you. FOr my screen capture I know ALT + PRINTSCREEN but I love my background For TakaIsSilly I'm really interested with you tile mode. Thanks all for your help.

		Only one pic for fun :

		racketboy	Dec 19, 2002
		little OT, but do you think we could start up a Dreamcast Dev section too?

		vbt	Dec 20, 2002
		Racketboy, you don't like Saturn ?

		vbt	Jan 5, 2003
		I don't have the time to work on it. try it on SSF, I think it doesn't work on a real saturn : SMS Emu, first try.... Help is displayed when you start the emu. Thanks all for your help (especially TakaIsSilly) I'll try to improve it soon, not only by myself but with everyone in this forum.

		vbt	Jan 6, 2003
		A little addition, I didn't say that the ISO has above 75 games and its size is 11.4 mo

		Daniel Eriksson	Jan 6, 2003
		Really nice work indeed!

		vbt	Jan 8, 2003
		Thanks no other feedback ?

		vbt	Jan 12, 2003
		I made small modifications, can someone tell me if it's faster on SSF or Satourne ? SMS Emu second Try... For slower connection, I can put a small release with 2 or 3 games.

		vbt	Jan 14, 2003
		Here is the small release with only3 games, but only few users seem to be interested . games included : - Outrun - R Type - Wonderboy SMS (475 ko)...

		Start a new thread with the title "WORKING MASTER SYSTEM EMULATOR FOR SATURN" and you'll get a bunch of feedback.

		IBarracudaI	Jan 14, 2003
		hey vbt... I am very interested... I just don't have the saturn here with me... and my daemon tools crash my windows... don't know why though... and I don't feel like burning a cd-r, I don't have any cdrw with me... :: ::

		mal	Jan 14, 2003
		Does it run on a Saturn or just emulators? If it does run on real hardware I'll give it a go.

		slinga	Jan 15, 2003
		I burned it for the hell of it (even though you specifically said not to...hey I have too many blank cds and even more free time ) Anyway it gets to the title screen where I can select which rom I want to use. I select the rom I want to play, and then the screen goes blank. The cd spins like mad, but nothing loads up. I'm quite impressed with your title screen btw...
