Re: pixels are not displayed
I decided to do per-tiles plasma.
But updated too slow.
void plasma()
{
if(initplasma==0)
{
ind = TILE_USERINDEX;
VDP_setPalette(PAL0, pix0.palette->data);
ind_pix0= ind;
VDP_loadTileSet(pix0.tileset, ind_pix0, TRUE);
map_pix0 = unpackMap(pix0.map, NULL);
ind += pix0.tileset->numTile ...
