BC: what does it do? I have read on hackmii that BC is very similar to boot1, and thus probably loads boot2.what does it do and (as bootmii is a boot2 patch) is it affected by bootmii?http://forum.wiibrew.org/read.php?27,8960,8960#msg-8960Sun, 10 May 2026 23:45:41 +0200 Phorum 5.2.23 http://forum.wiibrew.org/read.php?27,8960,48020#msg-48020 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,48020#msg-48020 Muzer SoftwareTue, 26 Jan 2010 22:16:35 +0100 http://forum.wiibrew.org/read.php?27,8960,47636#msg-47636 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,47636#msg-47636

If the BC can underclock the CPU and GPU, would it be possible to modify the BC to overclock the the CPU and GPU?

Why does BC have any special privileges? Bootmii probably could under/overclock anything.]]> metroid_maniac SoftwareThu, 11 Jun 2009 18:43:43 +0200 http://forum.wiibrew.org/read.php?27,8960,20195#msg-20195 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,20195#msg-20195 timmy112 SoftwareThu, 11 Jun 2009 13:41:26 +0200 http://forum.wiibrew.org/read.php?27,8960,15200#msg-15200 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,15200#msg-15200 bushing SoftwareThu, 23 Apr 2009 14:52:11 +0200 http://forum.wiibrew.org/read.php?27,8960,15159#msg-15159 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,15159#msg-15159 cl87 SoftwareThu, 23 Apr 2009 04:02:03 +0200 http://forum.wiibrew.org/read.php?27,8960,14932#msg-14932 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,14932#msg-14932 metroid_maniac SoftwareMon, 20 Apr 2009 08:18:23 +0200 http://forum.wiibrew.org/read.php?27,8960,14857#msg-14857 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,14857#msg-14857
If there is, here's an idea.

If anything tries to start BC, your code traps it, sets the register, and goes to normal boot2 from there. Essentially, skip BC.]]> WikiFSX SoftwareSun, 19 Apr 2009 22:30:11 +0200 http://forum.wiibrew.org/read.php?27,8960,14843#msg-14843 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,14843#msg-14843 bushing SoftwareSun, 19 Apr 2009 13:18:25 +0200 http://forum.wiibrew.org/read.php?27,8960,14837#msg-14837 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,14837#msg-14837 metroid_maniac SoftwareSun, 19 Apr 2009 12:18:13 +0200 http://forum.wiibrew.org/read.php?27,8960,12732#msg-12732 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,12732#msg-12732
So games would not work in my opinion

Is there even anything that prevents us from loading gamecube code while running at full spped in WiiMode?
Anyway, I do not see the reason..
For example the overclocked DS:

For reasons not quite clear, the System Menu does not directly load MIOS to boot a GameCube game. Instead, it launches BC, which is almost identical to boot1. The only major difference is that it sets a register which slows down the Hollywood clock speed to that of the Flipper (found in the GC).

When boot2 runs, it checks that clock speed; if it's in the slower mode, it starts MIOS instead of the System Menu.

Does that mean that it would be possible to install a patched BC and BOOT2 to slow down the clock to something like a fraction smaller than what the Wii uses ordinarily, as opposed to the value that GameCube uses, so that GameCube games can load using the Wii clock speed (minus 0.01 or something), and have a much faster clock speed in GameCube mode..?]]> SoraK05 SoftwareSat, 14 Feb 2009 13:56:35 +0100 http://forum.wiibrew.org/read.php?27,8960,9284#msg-9284 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9284#msg-9284 svpe SoftwareSun, 01 Feb 2009 16:10:02 +0100 http://forum.wiibrew.org/read.php?27,8960,9283#msg-9283 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9283#msg-9283

system menu detects GC game and loads BC
BC changes clock speed and loads boot2
boot2 detects clock speed and loads MIOS
MIOS loads gc game]]> metroid_maniac SoftwareSun, 01 Feb 2009 16:08:54 +0100 http://forum.wiibrew.org/read.php?27,8960,9213#msg-9213 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9213#msg-9213IOS).]]> bushing SoftwareSun, 01 Feb 2009 00:34:33 +0100 http://forum.wiibrew.org/read.php?27,8960,9170#msg-9170 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9170#msg-9170 metroid_maniac SoftwareSat, 31 Jan 2009 08:58:51 +0100 http://forum.wiibrew.org/read.php?27,8960,9145#msg-9145 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9145#msg-9145 bushing SoftwareFri, 30 Jan 2009 23:14:14 +0100 http://forum.wiibrew.org/read.php?27,8960,9033#msg-9033 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9033#msg-9033 metroid_maniac SoftwareThu, 29 Jan 2009 15:52:46 +0100 http://forum.wiibrew.org/read.php?27,8960,9025#msg-9025 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,9025#msg-9025

Unless we do something to specifically prevent it, BC will load BootMii, yes. Also, new versions of BC (like those released several months ago) will refuse to load BootMii, so that will actually break GC compatibility :/]]> bushing SoftwareThu, 29 Jan 2009 14:25:45 +0100 http://forum.wiibrew.org/read.php?27,8960,8977#msg-8977 Re: BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,8977#msg-8977 tona SoftwareWed, 28 Jan 2009 17:11:50 +0100 http://forum.wiibrew.org/read.php?27,8960,8960#msg-8960 BC: what does it do?http://forum.wiibrew.org/read.php?27,8960,8960#msg-8960 metroid_maniac SoftwareWed, 28 Jan 2009 14:09:56 +0100
