Notes
Note:There is not present one PSG (the middle precisely),probably to reduce production costs.So,some sfx are missed :When you die. Sound cpu ram was been reduced,too:The 6116 was been replaced by two 2114.
bjb_13 and bjb_14 part of main program.The first half of eproms are identical to 11_m01b and 09_j01b respectively,the second half to 12_n01b and 10_l01b The rest are identical to existing set 1.
