|
|
|
; |
|
|
|
; THE TOP (MASTER CONFIGURATION) FILE DEFINES ALL POSSIBLE ROMWBW |
|
|

; CONFIGURATION SETTINGS. EACH FILE BELOW THE MASTER CONFIGURATION FILE |
|

; INHERITS THE CUMULATIVE SETTINGS OF THE FILES ABOVE IT AND MAY |
|
|

; OVERRIDE THESE SETTINGS AS DESIRED. |
|
|
|
; |
|
|
|
; OTHER THAN THE TOP MASTER FILE, EACH FILE MUST "#INCLUDE" ITS PARENT |
|
|
|
; FILE (SEE #INCLUDE STATEMENT BELOW). THE TOP TWO FILES SHOULD NOT BE |
|
|

; MODIFIED. |
|
|
|
; |
|
|
|
; TO CUSTOMIZE YOUR BUILD SETTINGS YOU SHOULD MODIFY THIS FILE, THE |
|
|
|
; DEFAULT BUILD SETTINGS (Config/<platform>_std.asm) OR PREFERABLY |
|
|
|
; CREATE AN OPTIONAL CUSTOM USER SETTINGS FILE THAT INCLUDES THE DEFAULT |
|
|
|
; BUILD SETTINGS FILE (SEE EXAMPLE Config/SBC_user.asm). |
|
|
|
; |
|
|
|
; BY CREATING A CUSTOM USER SETTINGS FILE, YOU ARE LESS LIKELY TO BE |
|

; OF YOUR SETTINGS WHICH WILL BE UPDATED BY AUTHORS AS ROMWBW EVOLVES. |

; *** WARNING: ASIDE FROM THE MASTER CONFIGURATION FILE, YOU MUST USE |
|
|

; ".SET" TO OVERRIDE SETTINGS. THE ASSEMBLER WILL ERROR IF YOU ATTEMPT |
|
|
|
; TO USE ".EQU" BECAUSE IT WON'T LET YOU REDEFINE A SETTING WITH ".EQU". |
