hello ,
this is my first try on the MAME emulator project. Board info : CPU : MC68000 8mhz Video : MC6845 Audio : AY3-8912
I have done for the moment : 1. mapping of the board 2. skeleton of the driver (software run, but still some i/o todo) 3. dump of ROM ,NVRAM, emulation of PAL
currently , I am lost in the decoding of the video section VIDEO RAM work with 2 BYTES 1 ATTRIBUTE BYTE (color + bank select) 1 TILE BYTE
there is a BYTESWAP at the output of ROM GFX plus a funny use of clock in the RASTER ROW.
I have attached a DUMP of the videoram and the schematic if someone can help me.
thanks
Yves
