** 2006-2008 Eke-Eke (Genesis Plus port), MAME backport by R. Belmont
|
||||
** 2006-2008 Eke-Eke (Genesis Plus GX), MAME backport by R. Belmont.
|
||||
** - implemented PG overflow, aka "detune bug" (Ariel, Comix Zone, Shaq Fu, Spiderman,...), credits to Nemesis
|
||||
** - fixed SSG-EG support, credits to Nemesis and additional fixes from Alone Coder
|
||||
** - modified EG rates and frequency, tested by Nemesis on real hardware
|
||||
** - fixed EG attenuation level on KEY ON (Ecco 2 splash sound)
|
||||
** - fixed LFO phase update for CH3 special mode (Warlock, Alladin), thanks to AamirM
|
||||
** - implemented LFO phase update for CH3 special mode (Warlock birds, Alladin bug sound)
|
||||
** - fixed Attack Rate update (Batman & Robin intro)
|
||||
** - fixed attenuation level at the start of Substain (Gynoug explosions)
|
||||
** - fixed EG decay->substain transition to handle special cases, like SL=0 and Decay rate is very slow (Mega Turrican tracks 03,09...)
|
||||
**
|
||||
** 06-23-2007 Zsolt Vasvari:
|
||||
** - changed the timing not to require the use of floating point calculations
