Some more discoveries:

• f5_620 needs a slightly different data bitswap from s10fake. The relevant line should be:

put_u16le(&romdata[i], (w & 0xfbfb) | (w & 0x0400) >> 8 | (w & 0x0004) << 8);

• s10_520 needs the vt36x_gbox2020_16mb opcode swap config and the following ROM patch to work around an apparent bug in the init code:

ROM_FILL( 0x07f3d9, 1, 0x64 )
