// memoryRemap256M
// Remap some of the eight 8K memory blocks in the 64K address space of the 6502 to point somewhere else in the entire 256MB memory space of the MEGA65.
// After the remapping the CPU will access the mapped memory whenever it uses instructions that access a remapped block.
// See section 2.3.4 in http://www.zimmers.net/cbmpics/cbm/c65/c65manual.txt for a description of the CPU memory remapper of the C65.
// See Appendix G in file:///Users/jespergravgaard/Downloads/MEGA65-Book_draft%20(5).pdf for a description of the CPU memory remapper of the MEGA65.
// remapBlocks: Indicates which 8K blocks of the 6502 address space to remap. Each bit represents one 8K block
// - bit 0 Memory block $0000-$1fff. Use constant MEMORYBLOCK_0000.
// - bit 1 Memory block $2000-$3fff. Use constant MEMORYBLOCK_2000.
// - bit 2 Memory block $4000-$5fff. Use constant MEMORYBLOCK_4000.
// - bit 3 Memory block $6000-$7fff. Use constant MEMORYBLOCK_6000.
// - bit 4 Memory block $8000-$9fff. Use constant MEMORYBLOCK_8000.
// - bit 5 Memory block $a000-$bfff. Use constant MEMORYBLOCK_A000.
// - bit 6 Memory block $c000-$dfff. Use constant MEMORYBLOCK_C000.
// - bit 7 Memory block $e000-$ffff. Use constant MEMORYBLOCK_E000.
// lowerPageOffset: Offset that will be added to any remapped blocks in the lower 32K of memory (block 0-3).
// The offset is a page offset (meaning it is multiplied by 0x100). Only the lower 20bits of the passed value is used.
// - If block 0 ($0000-$1fff) is remapped it will point to lowerPageOffset*$100.
// - If block 1 ($2000-$3fff) is remapped it will point to lowerPageOffset*$100 + $2000.
// - If block 2 ($4000-$5fff) is remapped it will point to lowerPageOffset*$100 + $4000.
// - If block 3 ($6000-$7fff) is remapped it will point to lowerPageOffset*$100 + $6000.
// upperPageOffset: Offset that will be added to any remapped blocks in the upper 32K of memory (block 4-7).
// The offset is a page offset (meaning it is multiplied by 0x100). Only the lower 20bits of the passed value is used.
// - If block 4 ($8000-$9fff) is remapped it will point to upperPageOffset*$100 + $8000
// - If block 5 ($a000-$bfff) is remapped it will point to upperPageOffset*$100 + $a000.
// - If block 6 ($c000-$dfff) is remapped it will point to upperPageOffset*$100 + $c000.
// - If block 7 ($e000-$ffff) is remapped it will point to upperPageOffset*$100 + $e000.
