WHAT:
Emulator of C= 64 for Amiga computers with 68020 or higher.
WHY:
Because A64 (both 2.0 and 3.0) sucks IMO. And I think the Amiga deserves
good emulators like the PC has.
HOW:
First you need 3 files: C64.BASIC, C64.KERNAL, C64.CHARSET.
These are just dumps of real C= 64 roms. They are not included because of
legal reasons, but I think several other emulators actually include them.
Put these files in the current directory or in the same directory you store
the executable.
You can now start the emulator. You can LOAD files that are in RAM: or C64:
(assign it where you have you your files). The fileformat is the same as
A64 uses. Disk images are not supported.
The keyboard is mapped nearly 100% like a real C= 64 so the keys wont
always match the Amiga keyboard. The RESTORE key is not mapped at all.
The joystick port of your Amiga maps to both C= 64 joystick ports.
Bank switching is supported (but I think there might be a bug in it.
Anyone?)
Hires character mode is the only mode supported.
Sound isn't supported.
There is no restart option, you have to quit the emulator with the ESCAPE
key or left mouse button.
SPEED:
No. Unless you have an 040/060 that can write 7M/s to chipram. Then perhaps.
Unlike many other emulators the relative speed of the screen update and the
cpu speed does not change, it will always run internally like a 1MHz PAL
C= 64, and never faster than a real C= 64.
WHY SELECT AXF-64:
It does a few things that A64 doesn't. It can do raster bars. It can do
raster interrupts and screen changes on a per line basis. It was made with
big cpus in mind.
TODO:
First to come is multicolour character mode. I have ideas and all, but I
need to test a little to see if I can make it fast enough.
AGA support. Not only align bitplanes for more DMA time under AGA, but also
use other algorithms to reduce chip bus activity.
Sprites. I have code and ideas for that too.
Bitmap modes.
All timers. I have ready code for that too.
Sound. Not sure what to do with this. Perhaps kludge in something with
PlaySID?
Support disk images.
Make different screen update modes for different configurations.
Since I'm doing my military service at the moment updates may be far and
few between, and I wont have any email until summer 1995.
I'll snailmail new updates to a friend of mine who will upload them.
