Altered Beast - ReToned & Music Transposed

ALTERED BEAST RE-TONED V1.17 and V1.19 MUSIC TRANSPOSED

This patch changes some colours from the original 1988 MegaDrive release, it's a tiny bit closer to the arcade version, some areas have enhanced contrast.

Some voice samples from the MegaDrive/Genesis version have been slightly altered.

If you prefer the original MegaDrive/Genesis YM2612 music style use V.1.17 and below.

If you prefer a "thicker" style that resembles YM 2151 music then V1.19 alters and transposes the music to make it sound in a similar key to the arcade version.

V.1.19 - Music should now be in the same key as the arcade. The previous version was a bit off by one semitone; this has been fixed, and V1.19 should now play all themes consistently (Apr'26).

V 1.18 - Everything in v1.17 + Additional Sound Enhancements (Apr'26):

-Music & SFX sound thicker and should now be a bit closer to the arcade

-Cleaned up some voice samples

V 1.17 - Additional subtle GFX enhancements (Apr'26).

V 1.16 - Further refinements (Feb'25).

V1.14a - Initial patch.

Tested on GENS & real hardware - Genesis Model 1 VA3 + Sony Trinitron 14FV300.
