C64: Writing to color RAM

[r1me]

I can write to color RAM only with poke command but not load, regardless of memory configuration value (0x30-0x37)
I noticed that while writing to memory with load command, memory config value 0x33 is applied if destination memory region is in I/O area. User setting is then ignored. My suggestion to solve this issue would be to add a new boolean if user specified a memory configuration.

xlink/client.c

Line 657 in c3681d9

if(range_overlaps(data, io))

if(range_overlaps(data, io)  && !user_specified_mem_cfg)
  command_apply_safe_memory_and_bank(self);
else 
  command_apply_memory_and_bank(self);

You're right, the user should of course get whatever they request, assuming they know what they're doing. No reason not to give them all the rope. But on the other hand, the command is called load, and that usually means loading into RAM.

I think I'd prefer to just remove the memory option from the load command completely, and instead implement a generic write command. This way load can be simplified and just always write to RAM while write will just use whatever memory config you request.
