I've tried it in this way (which is certainly wrong):
void senterp_state::main_map(address_map &map)
{
map(0x0000, 0x0014).m(m_maincpu, FUNC(hd6301y0_cpu_device::m6801_io));
map(0x4000, 0x47ff).mirror(0x3800).ram(); // internal
map(0xc000, 0xffff).rom(); // internal
}
Hello Fhub,
Ram from 0x4000 to 0x47ff : 2 k RAM.
The HD6301Y has only 256 bytes, so from 0x4000 to 0x40ff.
Cordially.
