Reads a hires image from disk into a buffer at 0xe000..0xff40 and displays it. The read can be performed without a secondary buffer, because writes to the ROM end up in the RAM underneath.

#### Fasload image data "hiresfload.c"

Use the oscar flossiec fast loader to load a compressed multicolor image to 0xe000..0xff40 and 0xcc00..0xcfff.

### Remapping memory "memmap"
|
||||
|
||||
The C64 memory map is very flexible. These samples show how to manipulate the memory map and use easyflash ROMs to execute larger programs.
