I was looking through the GitHub source code and the wiki for PrizmSDK but under syscalls I saw that there was no Bdisp_DrawLineVRAM. I was wondering what happened to this syscall because I’ve seen it used before, and I would assume it’s semi-essential for drawing polygons.
I think this is just a different name for another syscall.
It could be referring to syscall 0x1D2, which I refer to as Bdisp_LineC16.
Here is an example of using the syscall:
Code:
Setting mode to one should draw the line, but for more info on this parameter, see simLo's documentation around TShape. The mode parameter is just f[2] of TShape, and f[3] is set to 1.
For more info, see my syscall documentation here. Page 4 describes the Bdisp Shape syscalls.
Let me know if the code doesn't work or if you have any other questions.

"jmp @r2; nop; 1: .long 0x1d2; "
"sc_addr: .long 0x80020070");
int main(void) {
// Bdisp_LineC16(unsigned int x1, unsigned int y1, unsigned int x2, unsigned int y2, int mode, unsigned short color);
Bdisp_LineC16(1, 1, 100, 100, 1, COLOR_GREEN);
int key;
while (1) {
GetKey(&key);
}
return 0;
}
