Discover a futuristic fast-paced platformer game in pixel art, which includes 2 mini-games, and developed for Megadrive, Gameboy and Dreamcast consoles, also available for PC on Steam. The game takes place in three different environments (prison, desert, forest) and is interspersed with 2 mini-games...

thd_pass() is what you're looking for. Or, perhaps you want thd_sleep(), if you actually want the thread to sleep and not just pass away it's timeslice... For what you're doing, it might be a good idea to look into condvars and other synchronization primitives, so that you don't have that second th...

what is the function to "sleep" the thread in KOS ?
I tried pthread_yield(); and shed_yield();, but both functions are not recognized in KOS sdk :/

no, only the main thread read from CD. meanwhile the second thread loop in an infinite while(flag); the flag is set to 0 when the CD loading from the main thread is finished, so the second thread can continue doing stuff, but never access the CD. btw, I'm using KOS 2.0.1, never had the success of co...

see update of the first post

I try to load data from CD with a thread running in background and it's damn slow ... When I load file from CD to ram without any thread started, it's fast, as it used to be. Now when I start a thread (which itself will initialize an ogg player which seems to start another thread), when I load data ...

http://onorisoft.free.fr/retroshop/zia.png I present to you my new game, it's an RPG, targeted for the Dreamcast, it took me 1 year of development. Here is the Story: In a world where magic is Queen, people lived happily and safely under the protection of the ten guardian goddesses. Out of the unkn...

Horizontal or vertical line are not a problem.
The problem is any direction line ...
I did the polygon in this order, because in the classic order it look worse..

I'm using the PVR for all my drawings, and I would like to draw a line, but I didn't find any command to that (even GL_LINES is not implemented in kGL) I tried to do it using a polygon (see code below) but it's not really working, so I wonder, how do you draw a line on the Dreamcast ? void PolygonDr...

I tried a trick which seems to work, even it's a dirty trick .. I init the polygon using "power of two" width & height, but if the image I need is taking less space, I only malloc "image width rounded to power of two" x "image height" (even if not power of two), the...

yes, sorry about that, I edited my post in the meantime.

I'm using KOS 2.0 downloaded from the website.

I will try the GIT version

There seems to be a bug in the texture memory management of KOS (pvr_mem_malloc) My game is in 640x480 and is using lots of texture, I had to reduce the vertex buffer to 192k to have more memory. Despite that, I still don't understand why there is only 5Mbytes of memory left for textures (are the 64...

Bump on this thread. I tried to delete the "65534" sample length limitation of the function "snd_sfx_play" but it doesn't change anything. So I assume the hardware limitation is no sample length more than 65534. Regardless of stereo mode, this means: Sfx can be maximum length of:...

Thank you, It finally works with the special flags.
I thought it was optional.
Now, playing with the values (0-7 specified in the .h) I get strange result, but I got something nice with value 7
(duration of 100 or 250 won't change anything though...)

Hello, I'm trying to use the purupuru function, but I can't get it to work :( I have a working vibration pack in my gamepad. And here is my code: (which produce no vibration at all) purupuru_init(); // <- Tried this but it locks the program, so I removed it void DC_Rumble(int value, int time) { mapl...

I read from here: http://mc.pp.se/dc/vms/flashmem.html Note that mini-game files are allocated starting at block 0 and upwards, while a data file is allocated starting at block 199 selecting the highest available free block. This is probably because a mini-game should be able to run directly from th...

The problem with KOS is that, it can do a lots of things, but there is not much example on how to use all theses features (ex: vmu games, purupuru)

I tried this function with the correct flag, but the VMU tells me the game is damaged. I tried to run DreamExplorer to check the data using the hex editor, and the data seems the same than the original file. Then I used the "defrag" option, and then the game was playable. So I guess, the d...

Well, I guess I'm going to learn another assembler then ...

Is there a way to write your game (.vms file) on the VMU using the Dreamcast / KallistiOS ?
I tried to write the VMS file raw on the VMU, but it's not recognized as a game by the VMU.
