Compatible with most 4.30+ CFWs and even HFW (as only unsigned rco and audio files are involved)
Extract these 3 files into {dev_blind, dev_rewrite, etc}/vsh/resource/ (overwriting the ones already present, and removing the now useless coldboot.raf from the same folder if desired), then reboot your console - there's no step 3!
If you want to implement it yourself (because you want to keep other custom_render_plugin.rco mods), extract it with RcoMage (leaving PNG and WAV conversions disabled), then edit the XML to redirect anim_coldboot2 to anim_coldboot as follows:
Code:
<Animation name="anim_coldboot2">
<FireEvent object="anim:anim_coldboot" />
</Animation>
[promptly replaces them]
