[no whatsnew after this!!!]

This consists entirely of diagnostic menus; it doesn't appear to bother being
able to load programs or anything, so getting it running would be interesting.

The dumper says:

"If you set region to 0x02 it does something, than mess crash...

READ64_HANDLER( dc_mess_g1_ctrl_r )
{
dc_state *state = space->machine().driver_data<dc_state>();
int reg;
#define retail 0;
#define set4_8m 0xc;
#define set4_32m 0x8;
#define devbox_16m 0x9;
#define devbox_32m 0xa;

#define reg_jp 0x1;
#define reg_usa 0x4;
#define reg_eu 0xc;
//other "region" trigger different selfttest mode on Katana DevBox

int region=reg_usa;
int box=devbox_16m;

UINT64 shift;

reg = decode_reg32_64(space->machine(), offset, mem_mask, &shift);
mame_printf_verbose("G1CTRL: Unmapped read %08x\n", 0x5f7400+reg*4);
printf("G1CTRL: Unmapped read %08x\n", 0x5f7400+reg*4);

if ((reg*4) == 0xb0){
return box<<4 | region;
}
return (UINT64)state->g1bus_regs[reg] << shift;
}"

...however it still does nothing for me even with the region set to 0x2.
