|
|
; Contains: This file contains information regarding hardware components used trought
|
|
; the source code. An explanation of each component name is given as well
|
|
; as the name of the CPUs which use the component. This is very useful for
|
|
; people new to ROM development. This is the place where you want to write
|
|
; all of those things you know about a particular chip. We need to know all
|
|
; of this things before you leave the project.
|
|
;
|
|
; Hint: If you want to know if a specific chip is used somwhere, look at the
|
|
; universal tables in UniversalTables.a
