Takayama has posted a pre-release:

New futures of 3.0t5-pre2
quick save/load state (call menu by press B pulling R trigger).
reset.
some bug fix which enbugged 3.0t5-pre.
be unstable. (sometimes crash by “unhandled IRQ/Exception”)
all of 3.0t5-pre (see below).

quick save/load make snapshot of working RAM, and restore. This will be clear when the game exits. No snapshot save to VMU. (it’s too large for VMU).

Now I’m brushing up source code. The reason “unhandled IRQ/Exception” maybe stack overflow… patch welcome.
