just for the fun of it, hello world in sh4 asm: .global _main _main: sts.l pr,@-r15 mov.l printf,r0 mov.l stringaddr,r4 jsr @r0 nop lds.l @r15+, pr rts nop string: .string "Hello Dreamcast in sh4 assembly\n" stringaddr: .long string printf: .long _printf

As far as I know, the aica-chip does not generate any sounds, it just uses samples to play sound.

Though, nothing stops you from making a softsynth for soundgenerating and use that with the dreamcast. But you might as well be using a pc then..

Kamjin, what's so hard about the GCC syntax?

and you'll still need a -S flag when you compile if you want assembly output -save-temps will only leave the raw object files. -save-temps works for me. To quote http://gcc.gnu.org/onlinedocs/gcc-3.4.0/gcc/Debugging-Options.html#Debugging%20Options -save-temps Store the usual "temporary" ...

yea well, i dont know how to get asm output =P Send the compiler flag "--save-temps" to gcc and it will save an ".s"-file for the file you are compiling. If there is a specific section in the code you want to check you can put something like this around it to easier find it in t...

No problem.. And in case you didn't spot it allready I see atleast two errors in the code I wrote. But "I'll leave that as an exercise for the reader" ;P

The better way to display an image would be to use the pvr, but since this tutorial seems to be about "manual" bytepushing here is something I wrote down from the top of my head: // Section 1: calculate acctual blitcoordinates blitEndX = min(posX + imageWidth, screenWidth); if (blitEndX ==...

They both use the same compiler.

Code smart, and don't blame the tools.

so we can visually know its possiblities over kos And I suppose that you don't own any commercial dreamcast games? All info I need/want (well.. except for the bumpmapping) is either in kos allready or have been released recently on the net. (I'm thinking purupuru and volume modifiers. Though I have...

Though, if you want to use it for regular 2d-stuff, then you don't have to deal with all those "features".

Yeah i have no idea really how to use 3d in kos but i do some what in katana. only due to the samples. Well, as I see it, if you can't figure out how to use the pvr-stuff from the headers/sources/examples in kos, then maybe you just aren't ready to use it. If you want easy to use 3d, then take a lo...

i want to be able to change only the last byte of an int to a different value, that isnt f. like, if it starts as 0101 i want to change it to 0001 and if it starts at 1111 then i still want to change it to 0001. maybe someone else will understand my question.... Acctually, four bits isn't a byte it...

well, I'm not sure what the "sndoggvorbis_isplaying()" function does.. Maybe return true when a song is playing? If so, then this won't work if your previous song is playing. Banlangd>9200 is where the boss area starts so naturally I want to change the current music to boss music. Judgeing...

I do it like this: if(banlangd>9275){ sndoggvorbis_stop(); sndoggvorbis_start("/rd/ljud/boss.ogg",1); } As soon as the program reaches this line it prints out hundreds of messages all saying: oggthread: initializing and parsing ogg oggthread: rereleased from semaphore (status=2) oggthread...

What about demos? (you know, variance by haujobb, delicious by yodel etc etc)

Hello. At a demoparty in Malm?, Sweden I released a 4k for the dreamcast which came at 3rd place (although both the coders of the 1st and 2nd place, and many more I have spoken with, thought that my entry should have won :)) anyway, download it from http://www.outbreak.nu/files/demo/2002/luftvarg.zi...
