jEnesisDS 0.7.4

A Sega Genesis/Megadrive emulator for DS.Changelog:********v0.7.4 * ********- Changed scheduling of M68000 and Z80. - Some changes in M68000 internal memory handlers. - YM2612 FM core mostly rewritten in ASM. - Some bugs in FM core fixed (Operator 1 was sometimes not considered in certain cases). - Fixed reset bug for FM core resulting in unstable sound for every game loaded except the 1st one. - Raised sample rate for FM emulation from 16KHz to 28KHz (28, because a few games can't do 32KHz) - Sound is completely mixed in hardware now, meaning every FM channel, PSG and DAC have their own DS sound channels.
