[uname1able]

I use manager.machine.devices[":gen_vdp/0/m_vram"] or ["Sega 315-5313 Megadrive VDP:/gen_vdp/0/m_vram"] get nil , how implent the code to get gen_vdp/0/m_vram memory by lua.

The current way of doing it is unsupported, and will change in an incompatible way in the future.

vdp = manager.machine.devices['gen_vdp']
vram = emu.item(vdp.items['0/m_vram'])

Note that accessing the items property is very slow, so avoid doing it frequently.
