* ROM Allocations
* ----------------------------------------------------------------------------
* The lib, data and game segments are compressed in the final ROM. To do this,
* we build them uncompressed here but place them past the end of the ROM, then
* mkrom compresses them and writes them into the ROM.
*
* These constants are defining how much space is reserved for the compressed
* segments. If these segments are edited and grow to a point that their
* compressed size exceeds the allocation then their allocations will need to be
* increased.
