Add code to check for memory-wraparound on the vertex buffer (it doesn't)
Add in-theory support for re-init (doesn't do anything)
Fix addresses of result and tilematrix
test/testta.c

Add high-memory tests
test/testta4.data

Add float_read, float_write for fp registers
test/lib.h

Implement open/close dcload syscalls, change permission flag to "unsafe"
src/dcload.c
src/main.c
src/syscall.h

Add alignment checks
src/sh4/sh4core.c

Add test for modifier context change in middle of vertex list
test/testta5.data

Add more bad_input calls
Start adding the no-list handling (not finished)
src/pvr2/tacore.c

Update error tests
test/testta5.data

Add some more clip tests
test/testta6.data

First pass at implementing the tile clip. Reasonably accurate wrt basic
understanding of how its supposed to work, not so accurate wrt actual
hardware behaviour
src/pvr2/tacore.c
