some fix to the m92 driver
the graphics and the sound ( hook , in the hunt )
to iq_132
it seems only m92 game need the v33 cpu , and no game need NMI i think.
the most trouble is the graphics. m92 has three tile layers and each layer owns two width mode, three transparent mode and also support line scroll mode. my code only implement a part of them to let that two game work , and still a bit layer order error .
the irem GA20 chip is a simple 4 channel PCM chip to play effect audio, the music base on it's YM2151 .
you can try other drivers if you have time. but i want to take some time to optimize the nec cpu emu for ARM based devices if free .
