◆ pico9918_splash_select_pro()
| void pico9918_splash_select_pro | ( | bool | pro | ) |
render the F18A's power-on badge into the scanline buffer
What PICO9918_CHIP_F18A shows where PICO9918_CHIP_PICO9918 shows its own splash. Not gated behind PICO9918_NO_SPLASH: that option drops the PICO9918's splash, and an F18A still has a badge.
outputLine is the host's OUTPUT line, not a display line, so one row of the badge is one physical scanline. Only a host driving pico9918_frame_output_line gets it; an interlaced one, which drives pico9918_frame_scanline per field, does not.
- Returns
- whether it drew, i.e. whether
pixelschanged.
choose the PRO artwork over the PICO9918's
pico9918_set_chip calls this; a host has no reason to. Only a runtime-chip build carries both images - a board resolves its one at build time.
