@ -7,6 +7,19 @@ Support for APF Imagination Machine cassette images
CPF and CAS images consist of the screen and then the program,
and are exactly 1E00 bytes in length.
APT images are much the same, however it includes a series of FF
bytes as a header. There's also a large amount of what seems to
be rubbish at the end.
APW images are not emulated, and are used by the closed-source
emulator APF_EMUW. Quote: "They allow recording in special formats
and recording audio. They are audio files sampled at 11025 Hz 8 bits
unsigned mono, without header. The bit 1 stores the state of the
recording head."
S19 images are not emulated, however there's no need to as they
are only used to hold cartridge hex dumps.
Each byte after conversion becomes bit 7,6,etc to 0, There are
no start or stop bits.
