20220412 -- twenty-third public release. CSFEC is a new Commodore 64 emulator: it passes several tests from the PC64 suite (CPUTIMING, CPUPORT and the entire MOS 6510 opcode set) but fails others (IRQ, NMI and all CIA tests); it supports up to two extra SID chips (either $D420 and $D440 or $DE00 and $DF00) but the VIC-II emulation is incomplete (no badline handling, no sprite contention); it can load PRG files and play T64 and TAP tape images, but it doesn't emulate the C1541 disc drive yet and thus cannot handle D64 disc images at all. New virtual joystick interface: the user can redefine the keys that simulate the virtual joystick instead of sticking to the keys Z and X and the cursors. Tape analysis can detect musical loaders: tape acceleration will be temporarily disabled to ensure that songs play normally. Fixed a bug in the Z80 (the internal timings of OUT (n),A were wrong) and the LA-7800's horizontal synchronisation (both reported by Hicks): the CPC demo "Onescreen Colonies #2" behaves properly.
