Never mind that last question about the registers... it's late
here... silly me.. ;-)

For those of you who are interested in KOS, I now have the romdisk file
system working and a new PCX loader that uses a new fs_mmap() call to
get a handle to the ROM image itself. I've got a little demo that loads
an arbitrary 240x160 PCX into a Mode 3 buffer. All you have to do is put
the PCX file in romdisk_boot (just like on the DC) and build.. voila! No
more converting to header files, etc..

I've found VGBA's arm debugger to be absolutely invaluable =). Does
anyone know of a way to do a pseudo-printf through that beast?

Hopefully within the next week or so I can do a release of KOS 1.1.0 for
DC and GBA (it's got both architectures in it). My GBA routines are a
bit immature right now but I'll be working on that pretty soon.
