DJB, a few things I'd like to point out:
I have to agree with Krayzie, that NKPatcher is better than PBL when distributing software that n00bs are bound to use, seeing as you have all the saftey features. I believe you did add NKPatcher options, but it was, what, NKP 8?
What Krayzie means why he says you should spend more time here, is to keep upto date on the latest releases, such as NKP 11.
As for debug support, I have developed a nice little disc installer which installs the XDK (not included), with a dual boot, for Krayzie's Ndure setups. See the link in my sig for info.
You say you developed SID around what you use? I did the same for this release, it was csomething I wanted to do, and thinking it useful, made it public. You need to, however, give some room for people to customize things themselves, like I did, by using simple setups. It's also a good idea to not include most of these options in the installer, as newbies will get confused, and make choices which may not be the best. Just give them something that works that they can't fuck up (shadowC and virtual EEProm sort of stuff). They can then learn what they need to to customize it later.
That is why I prefer Krayzie's installers. I hear about way more problems with SID than Krayzie's. Again, back to debug support. Why not go for the option that makes the most sense when you are distributing it to other people who don't have a clue about what theyre doing, then make a custom install for yourself? Most people are not even smart enough to know where to find the XDK, nevermind use it.
We need a rewiew board, like the DVD Format Forum, who decide what the current standards are, and that all installers that want to be certified, must comply to them.
