Re: Elysian Shadows Kickstarter Live NOW!

Actually, a very large amount paid for the tool and not the game. Once again, you are making an assumption without actually knowing the facts. Well, I'm just looking at your Kickstarter page, how many people paid for the creation rewards ? about 1% of the total The Kickstarter was about an RPG game...

Re: Elysian Shadows Kickstarter Live NOW!

The Kickstarter was about an RPG game, not an RPG Maker.
You build a really nice tool that only you can use for now, but you miss the game that people are waiting for, a nice game engine without content is useless.
People didn't pay you for a tool, they paid for a game.

Re: pthread and fs_read slowdown

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...

Re: pthread and fs_read slowdown

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 :/

Re: pthread and fs_read slowdown

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...

pthread and fs_read slowdown

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 ...

Drawing a line (with pvr)

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...

Re: KOS Texture memory management bug

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 remaining height will not be disp...

KOS Texture memory management bug

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...

Re: KOS snd_sfx_play problem

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: seconds = 65534 / S...

Re: Purupuru functions not working ?

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...)

Re: VMU programming in C language ?

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)
