Status [?] Confirmed Driver apple2e.cpp
Version 0.176 Fixed in Version Build Normal
Summary MESS-specific 06333: apple2e, apple2ee and clones: Fantavision: pwm/sound is too fast!
Description NOTE: This occurs on every copy of Fantavision for IIe, whether cracked or uncracked. There is no official copy in the softlist right now due to not having a proper crack release (4am!!!)

The PWM driver in Fantavision is performing too fast in emulation, which makes SFX play too fast. Inaccurate interrupt timing? At the bottom are attachments comparing HW to MESS 0.176.

Disk used for demonstration (random crack, educational purposes only!):
ftp://ftp.apple.asimov.net/pub/apple_II/images/productivity/graphics/misc/FANTAVISION.dsk
Steps To Reproduce 1. boot up a copy of Fantavision
2. play error SFX by performing an impossible operation (creating a circle after already creating one)
Additional Information verified with original machine + original disk with copy protection.
Flags Verified with Original
