/**

* The `framebuffers` segment is located at a fixed location in RAM and has a
|
|
* fixed size.
|
|
* Those framebuffers are placed at the end of the RAM space.
|
|
* This address is calculated by doing `0x80800000 - (size of framebuffers)`,
|
|
* where 0x80800000 is the end of the Expansion Pak address range.
|
|
* In the vanilla game this value expands to `0x80780000`.
|
|
*
|
|
* Since the start of the `framebuffers` segment is the end of the not-fixed
|
|
* available RAM, then the `system_heap` covers all the remaining RAM that is
|
|
* not used by the non-relocatable code/data (i.e. `boot`, `code`, and other
|
|
* buffers) up to the start of the `framebuffers` segmemt.
|
