If you are looking to improve your driver, you should submit to MAMEDEV your changes and not file a bug reports until the game is in a working state.

Three SRAM banks of 0x800 in size, i.e. 0x000-0x7ff (video ram), 0x800-0xfff and 0x1000-0x17ff (stack ram). 0x1802-0x1fff is unused so there's no ram.
I agree with Tafoid anyway.
