Re: Widescreen mode and kos ?

^ You're right but it still flickers. Is the main goal only to get this to work on computer screens or regular ntsc tv's as well?

Re: Widescreen mode and kos ?

Have you create a directory "romdisk" and put the resol.png in ? Do you use the makefile I posted ? When you launch "make", does it create a "romdisk.img" ? Yes, Yes, Yes EDIT: Added #include <kos.h> to your headers and the makefile I used: TARGET = dcp.elf OBJS = reso...

Re: Networking with the BBA

I was just wondering. Did you get an unhandled exception when your DC crashed? In the future you could do what they did in this thread: viewtopic.php?f=29&t=47741&start=0&st=0 ... +exception

Probably should have told you that in the beginning: viewtopic.php?p=1009854#p1009854

I would get an error since

Code: Select all

const char *pPtr = pBuffer;

Re: __attribute__

Wow, I would never figured that out. Thanks again BlueCrab.

btw, I got errors but the following code worked. For anybody who has the same problem.

Code: Select all

static inline word read_word(const char *ptr) {  // changed from byte to char
    return ((word)(*ptr)) | (((word) *(ptr + 1)) << 8);

I think you may be right about it never failing. This time I ran dc-tool-ip and sent the output to log.txt file.

I am having trouble getting PLX lesson 30(NeHe lesson 31) to work on the Dreamcast. I ported it and was able to get it to work on the NullDC emulator but when I load it into the Dreamcast it immediately closes because it can't load the milkshape model. I have tracked down the problem to the followin...

Re: Drawing rgb565 image in output_buffer using PVR

I seriously doubt you're using a twiddled texture (as the example code that was posted assumed). Wouldn't the pvr_txr_load_ex() function twiddle it for him? pvr_poly_cxt_txr(&Image_context, PVR_LIST_OP_POLY, PVR_TXRFMT_ARGB1555 | PVR_TXRFMT_NONTWIDDLED, Image_width, Image_height, Image_data, PV...

Re: Drawing rgb565 image in output_buffer using PVR

I think my problem is Im not sure exactly what parameter to pass here. //rawimagedata is the image data you have stored in memory. Is it the name of the variable that represents the location in memory? Yes, its a pointer to the raw data (decoded rgb565 frame). Make sure it is a pointer to one singl...

Re: Drawing rgb565 image in output_buffer using PVR

I'll try and help. So the image is stored in memory and it is uncompressed correct? If so, you could do something like this(pseudo code): uint16 Image_width, Image_height; pvr_poly_hdr_t Image_Header; // The thing that is submitted to the PVR before drawing pvr_poly_cxt_t Image_context; // Used to m...

Re: Transparency Problem

You tested that on a dreamcast didn't you? If so I feel bad. I've been using NullDC to test. Too lazy to get my Dreamcast and hook it up. I just tested it right now the way I originally had it and it works on Dreamcast. I'm really sorry for wasting your time dude. I'll test on the Dreamcast from now...

Re: Transparency Problem

Tried it and it just darkens the textures when I enable blending. No transparency occurs at all for any face of the box. I ported some drawables from Feet of Fury for Tsunami a while back including the Cube drawable. Blending works fine with it and I don't even have to do any of the "plx_cxt_bl...

Re: Transparency Problem

I thought of that blending mode of the context already. I think there might be a bug in the PLX library because by default the plx library creates it's context by the pvr_poly_cxt_col(pvr_poly_cxt_t *dst, pvr_list_t list) function which does this: dst->blend.src_enable = PVR_BLEND_DISABLE; dst->blen...

Transparency Problem

I'm trying to port the NeHe OpenGL lessons to Dreamcast using the PLX (Parallax) library located in kos-ports. For NeHe lesson 8 (Blending: http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=08) I have to get a cube to be transparent. The problem that I am having is that which ever face of the c...

LuaPlayer for Dreamcast

Would anybody be interested in a port of LuaPlayer to Dreamcast?

I could try and port it. Is there anything I should be aware off that would make it unportable to the Dreamcast so I don't waste my time in trying?
