NEW STUFF:
Yes, today was Dec-29, and i promised to release everything. The good news are that we have build almost 3 working boards now but off course nothing is bugfree.
So please, unless you know what you're doing, don't build this board yet in the hope it will just run! You need at least a scope and a soldering iron (and now how to use them).
The IPL replacement CVS is in the gc-linux cvs. I think you'll find it there.
The schematisc, VHDL sources (sorry for just making a backup of my ispLever working directory - i'll clean it up in the next release) and tool sources are here.
There's one problem left: the serial port doesn't fit together with the exi logic into the design, so currently you have to flash the ipl_serial stuff if you want to flash using the serial port, or ipl when you want to use the thing (you can flash from the gamecube if there's a valid loader inside.
oh, and PLEASE: *NO PIRACY* (this includes so-called "legal backups" - if you want to lie to yourself: do that. I won't.) or this site WILL be shut down, either by nintendo or by me.
NOTE: There is no so-called "scene-standard" for bootloader replacements. Other bootloaders can't boot homebrew at all (yes, of course, you can always replace the complete bios with a homebrew developed one, but that's not more convenient than using PSO), and otherwise there is no need for a "standard" as every bootloader should support loading of at least DOLs and probably ELFs directly. This bootloader doesn't support the special, undocumented "security"-features like other modchips, which are only there to bind software to specific hardware and protect their invested money into (probably) bought hacks. Effectively this disallows a *real* standard, which allows interoperatibility between different software and hardware solutions.
I know that people are telling you different things, but these are the same people who are - more or less - actively involved in selling commercial (pirate) modchips.
