+-- Main features
+--  15KHz(TV) / 31Khz(VGA)
+--  PAL(50Hz) / NTSC(60Hz)
+--  PS2 keyboard input with portA / portB joystick emulation
+--  SID sound output
+--
+--
+--  Internal emulated 1541 on raw SD card (READ ONLY) : D64 images start at 256KB boundaries
+--  Use hexadecimal disk editor such as HxD (www.mh-nexus.de) to build SD card.
+--  Cut D64 file and paste at 0x00000 (first), 0x40000 (second), 0x80000 (third),
+--  0xC0000(fourth), 0x100000(fith), 0x140000 (sixth) and so on.
+--  BE CAREFUL NOT WRITING ON YOUR OWN HARDDRIVE
+--
+--  Use only SIMPLE D64 files : 174 848 octets (without disk error management)

+--
+-- c1541_sd reads D64 data from raw SD card, produces GCR data, feeds c1541_logic
+-- Raw SD data : each D64 image must start on 256KB boundaries
+-- disk_num allow to select D64 image

+-- c1541_logic    from : Mark McDougall
+-- spi_controller from : Michel Stempin, Stephen A. Edwards

+-- T65            from : Daniel Wallner, MikeJ, ehenciak
+--
+-- c1541_logic    modified for : slow down CPU (EOI ack missed by real c64)
+--                             : remove IEC internal OR wired
+--                             : synched atn_in (sometime no IRQ to CPU with real c64)
+-- spi_controller modified for : sector start and size adapted + busy signal
+-- via6522        modified for : no modification
