Has an attempt been made for the roms to checkout if they gfxdecode cleanly with a 1bpp linear layout?

Before your machine_config:
static GFXDECODE_START( gfx_ibm3477 )
GFXDECODE_ENTRY("maincpu", 0x0000, gfx_8x8x1, 0, 1)
GFXDECODE_ENDThen, in your machine_config, around palette declaration:
GFXDECODE(config, "gfxdecode", "palette", gfx_ibm3477);F4 menu, press enter once, scroll down with directional arrows and check if there's some kind of clear GFX in there. If it does then the HW has some kind of Programmable Character Generator so the NO_DUMP is redundant.

Thanks!!
I see some loose characters, but cannot find a complete charset... Enough to say that there's not a missing separate character ROM?

Last pic shows enough to suspect this using a PCG yes, so please just remove that NO_DUMP flag, thanks.

Done, thanks a lot!!

m_p_chargen lines needs removing now.
