 ## CPCHawk
 
-This may or may not work out. But I figured I could at least start by building on the existing ZXHawk implementation (the machines do have CPU, tape format, PSG and disk drive/controller in common).
+Still very much work in progress....
 
-We'll see how that goes...
+#### In Place
 
-#### In Place (but probably requires more work)
-
-* CPC464 model template
-* Non-paged memory
-* Standard lower and upper ROM
+* CPC464, CPC6128
 * Port IO decoding
+* i8255 Programmable Peripheral Interface (PPI) chip emulation
+* AY-3-8912 PSG (and Port IO)
+* Keyboard/Joystick
+* FDC and FDD devices
+* .DSK image parsing and identification (to auto differenciate from ZX Spectrum disk bootloader)
+
+#### There, but needs more work
 * CRCT (Cathode Ray Tube Controller) chip emulation
 * Amstrad Gate Array chip emulation
-* Video rendering (mode 1)
-* i8255 Programmable Peripheral Interface (PPI) chip emulation
-* AY-3-8912 PSG Port IO
-* Keyboard/Joystick
+* Video rendering (modes 0, 1, 2 & 3)
+* Datacorder (tape) device
 * .CDT tape image file support
 
 #### Not Yet
-
-* CPC664, CPC6128, CPC464plus, CPC6128plus, GX4000 models
-* RAM banking
-* Upper ROM banking
-* Video rendering (modes 0, 2 & 3)
-* AY-3-8912 PSG sound output
-* Datacorder (tape) device
-* FDC and FDD devices
-* .DSK image parsing and identification (to auto differenciate from ZX Spectrum disk bootloader)
+* CPC664, CPC464plus, CPC6128plus, GX4000 models
 * Expansion IO
 
+#### Known Issues
+* The CRCT and Gatearray chips are undergoing a re-write at the moment, so video emulation is nowhere near accurate (yet)
+* .CDT tape image files will nearly always fail to load - timing conversion is still needed (so the tape device 'plays back' at the wrong speed)
