Maybe this sound a bit harsh, but if you can't code, RFTM:
Memory Configuration
The signals /CharEn, /HiRam and /LoRam are used to select the memory
configuration. They can be set using the processor port $01. The following
logic applies (if expression on the right side is true, area mentioned on
the left side will be activated. Otherwise, there is RAM):
Kernal ROM = (/HiRam)
Basic ROM = (/LoRam AND /HiRam)
That means, you cannot switch in Basic when the Kernal is off. Please
note also, that an EPROM starting at $8000 will be disabled when you
switch off the Basic ROM.
Char. ROM = ((NOT (/CharEn)) AND (/LoRam OR /HiRam))
I/O-Area = (/CharEn AND (/LoRam OR /HiRam))
These two areas can just be activated, if at least one other signal is
high. Then /CharEn selects either Char. ROM or I/O-Area.
As a result, we get the following possibilities for the corresponding
bits of $01:
Bit+-------------+-----------+------------+
210| $8000-$BFFF |$D000-$DFFF|$E000-$FFFF |
+---+---+-------------+-----------+------------+
| 7 |111| Cart.+Basic | I/O | Kernal ROM |
+---+---+-------------+-----------+------------+
| 6 |110| RAM | I/O | Kernal ROM |
+---+---+-------------+-----------+------------+
| 5 |101| RAM | I/O | RAM |
+---+---+-------------+-----------+------------+
| 4 |100| RAM | RAM | RAM |
+---+---+-------------+-----------+------------+
| 3 |011| Cart.+Basic | Char. ROM | Kernal ROM |
+---+---+-------------+-----------+------------+
| 2 |010| RAM | Char. ROM | Kernal ROM |
+---+---+-------------+-----------+------------+
| 1 |001| RAM | Char. ROM | RAM |
+---+---+-------------+-----------+------------+
| 0 |000| RAM | RAM | RAM |
+---+---+-------------+-----------+------------+

/CharEn|/LoRam

/HiRam

This should solve all your saving problems in future (and your packing problems which seems not to derive from the packers/linkers/cruncher you're using...)
Just my 2 cents... |

Of course I meant "if you want to save the _RAM_".
(Now where did that edit button go again...?) |

Yes your post was harsh. I know how to set $01.
The monitor would not save that area of memory unless it was transferred out. I DON'T use Vice, so all of this
(ad)Vice I'm getting is of no use. (Again, I did NOT use Vice during this problem)
The monitor does not expose RAM when the $01 is set. And the matter of linking, the problem remains that the three packers I used that claimed to pack $0200-ffff (or $0400-ffff) failed. They crashed.
Whether I saved the entire RAN from $0400-ffff as a single file or little files, the linkers I use choked.
Anyway the matter has been solved... I found a linker (Exomizer) that did it perfectly. |

Just for the record.
The CCS64 emulator also has an mc-monitor reached by [alt]+[m]. This monitor, like Vice, has a bank command to control what is displayed: memory, io or roms.
However, this bank command takes a number between 0-7 that corresponds directly to the last digit of the hexvalue normally in $01.
So the following command should save only memory in ccs64 to the current directory:
bank 4
sp "name" 0400 10000
(sp to save .prg file, only s excludes the two initial address bytes).

Cool. I did not know about the SP command. I've been saving the files like $0ffe-$4000 instead of $1000-$4000 to get the 2 initial load addresses.
I learned something new today :)

I have a tip: lowercase. Believe me, people will not listen to you using caps all the time. |

Another hint: Avoid posting stuff completely irrelevant to a certain thread. ;-)
Besides, it's really unclear to me what exactly your problem is. For games I suggest you visit gamebase64.com or lemon64.com. |

Never use capital letters iun forums, and that. Mainly because it is judged as flaming or shouting at another person. Use lower case please.
By the way, if you're a first time user and you're after an emulator for a PC Mac then http://www.zzap64.co.uk/c64/c64emulators.html#mac should hopefully help you.
BTW: This should go into a new thread ;) |
