 |
|
Hey im working with the nesterj 1.11 source trying to add a resolution that renders the pixels properly just like full screen setting but shrunk to 4:3. The source actully looks quite easy to manipulate i just need to change about 5 lines ive worked with NesDS (this looks like cake compared to it) if i could just get a bit of help would be nice ive got the right idea a bit of proof reading would help here is the lines i have changed

void BitBlt_FullScreen(void)

unsigned long *pVram;
pVram = (unsigned long *)pgGetVramAddr(0, 0);
for (y = 0; y < 224; y++) {
for (x = 0; x < 240; x+=2) {
cpy2x(&pVram[x], (g_Pal[g_ScrBuf[y + 8][x + 16 + 1]] << 16) + g_Pal[g_ScrBuf[y + 8][x + 16]]);
}
pVram += (LINESIZE/2);
dy += 21300;
if (dy >= 100000) {
dy-=100000;
for (x = 0; x < 240; x+=2) {
unsigned long ulColor = PBlend((g_Pal[g_ScrBuf[y + 8 ][x + 16 + 1]] << 16) + g_Pal[g_ScrBuf[y + 8 ][x + 16]],
(g_Pal[g_ScrBuf[y + 8 + 1][x + 16 + 1]] << 16) + g_Pal[g_ScrBuf[y + 8 + 1][x + 16]]);
cpy2x(&pVram[x], ulColor);
}
pVram += (LINESIZE/2);
