HalfNes 0.050 (8/9/2012)

• Lots of minor improvements for this release, and new mapper support as well. Thanks to Nawrot Kryzystof for many of these fixes.

Added Mappers:

• Mapper 10 (Fire Emblem, Famicom Wars)
• Mapper 19 (Megami Tensei II, Rolling Thunder (J), etc.) with expansion sound
• Mapper 34 (Impossible Mission II)
• Mapper 38 (Crime Busters)
• Mapper 64 (Klax, Rolling Thunder (U))
• Mapper 70 (Kamen Rider Club)
• Mapper 89 (Mito Koumon)
• Mapper 93 (Fantasy Zone (J))
• Mapper 94 (Senjou no Oukami)
• Mapper 97 (Kaiketsu Yanchamaru)
• Mapper 107 (Magic Dragon)
• Mapper 140 (Bio Senshi Dan)
• Mapper 152 (Arkanoid 2)
• Mapper 180 (Crazy Climber)
• Mapper 185 (Spy Vs Spy (J) but NOT Banana)
• Mapper 200 (36-in-1 Multicart)
• Mapper 203 (35-in-1 Multicart)
• Mapper 240, 246 (More Chinese original games)

Fixed:

• Fixed DMC timing (passes DMC basics test and makes Bee 52 work better)
• CPU interrupt is delayed so CLI+SEI only causes 1 interrupt after SEI (fixes Break Time, Hebereke)
• Fixed APU frame counter reset to within 1 CPU opcode of correct timing
• Fixed APU sweep behavior when clocked then immediately reset (Super Mario Bros. sound effects, Driar wrong notes in music)
• Updated VRC7 sound to use new patch set from nesdev, changed the way modulator feedback works, increased envelope attack rate
• Added CRC to options menu to make verifying dumps easier
• Fixed Uchuusen - Cosmo Carrier mirroring
• Fixed bug with file dialog where it wasn't clearing the old name when loading a ROM by double clicking

Broke:

• Lagrange Point intro was broken by the CPU interrupt change. Game is still playable.
