Thanks for sharing! I find this to be very useful.

I wonder if 0-5 volts logic is safe for the PSX because I happen to have a CH340 clone (disguised as a USB-RS232 cable) which outputs 0-5 volts logic.

Its possible since the Serial I/O port on the back of the PlayStation is RS-232 compatible but you'll need to build an adapter circuit to convert the voltages and you'll need to replace the proprietary Serial I/O connector on your PSX with a DB-9 connector. Here's the build instructions for making s...

Thanks!

t0rxe mentioned in one thread that he'll make a tutorial about mastering CD images with XA streams after the competition but, where is the tutorial? Ever since I started coding for the PlayStation, I have no idea how to incorporate XA streams of any kind into my CD image. I'm also wondering if this ...

One thing I know about reducing texture distortion on the PlayStation is to increase the number of polygons on the surface. I know this sounds inefficient but that's how most PlayStation games reduce texture distortion and it also helps with reducing sorting and clipping errors. And I'm glad that yo...

I'll take this little snippet of yours as a reference while I'm learning how the 3D graphics system of the PlayStation works. I'm not really sure if textured quads suffer from affine texture distortion that most PlayStation games suffer from.

Whenever I call CdReadFile or call it multiple times, it sometimes freezes depending on the number of files I stuck into the CD image. My program uses a pretty simple cache system using a 16KB buffer to make file access a lot easier for me to do. The problem is, when CdReadFile is called again to re...

Have you tried burning the raw image file included in the attached zip file into a CD to get my code to work?

EDIT: Never mind. I managed to fix the problem myself (I used an incorrect pointer type for destptr)...I'll release the fixed code once I add a file selector.

Did you guys forget about helping me with this pointer problem? No one seems to cooperate about it at all! Oh well, time to scrap this little project. I don't really know if this is the proper way to manipulate a pointer: memcpy(destptr + CdDestOffs, &CdBuff[CdBufferOffs], CdCopyBytes); Or no on...

someone has an editor with image file extension Bs? Unfortunately, you can't edit those files but you can convert a bitmap image into a BS image using MC32 in your bin folder. BS files are like JPEG images except its MDEC compatible and the file format is most likely similar to STR video files only...

I'm currently working on one but I'm having trouble with my buffered file loader...I'll release it along with source once I've fixed the problem and adding a file selector. http://i1344.photobucket.com/albums/p659/LameGuy64/LoadProblem_zps5f41b269.png Link to the thread: http://www.psxdev.net/forum/...

I'm currently working on a 24-bit bitmap loader for experimental purposes and I was able to get it to work but there's something wrong with my CdEasyFileRead function that has something to do with how I treat the pointers (which I'm pretty sure is incorrect). Attached in this post is a ZIP file that...

I'm currently working on a 24-bit bitmap loader to play around with the unused 24-bit color mode of the PlayStation. The problem is, I can't seem to read the 54 byte header off of a file for some reason. The code: // Includes #include <sys/types.h> #include <libapi.h> #include <libetc.h> #include <l...

It would have been interesting if Sony did release such a modem as that could make the PlayStation the first home console to have on-line multiplayer support before the Dreamcast. I'm also wondering if the mouse portion of that keyboard and mouse adapter works on PS1 games that supports the PlayStat...

Oops, I've made a mistake on the corrected code...You're supposed to add a & before the array name when passing an array with an index. So, it should be like this: extern unsigned char mat0[]; tpage[0] = LoadTPage((u_long*)&mat0[0x80], 0, 0, 640, 0, 256,256); clut[0] = LoadClut((u_long*)&...

Like I said, pass the array pointers as (u_long*). So your code from this: extern unsigned char mat0[]; tpage[0] = LoadTPage(mat0+0x80, 0, 0, 640, 0, 256,256); clut[0] = LoadClut(mat0, 0,500); Should be this: extern unsigned char mat0[]; tpage[0] = LoadTPage((u_long*)mat0[0x80], 0, 0, 640, 0, 256,25...

I think this is part of Sony's cancelled plan to add online capabilities for the PlayStation where a dial-up modem would be connected to the Serial I/O port and this adapter is used for players to be able chat with other players in a online chat room or hub by using a standard PS/2 keyboard.

me too. nicely done mate. btw. thanks for the Greetings :) i made a "Plasma Cracktro" for PS1 in the past too. (2001) i'll refresh the code with a nice 3D object and publish the Demo later in here. Thanks! And you're welcome about the greets. Do you have the link to your Plasma Cracktro f...
