Usage: $0 <command> <args>
|
|
|
|
<command>+<args> should be an ld65 command line with exactly one object
|
|
file containing
|
|
|
|
Appends --start-addr <address> to <command> if the first object file in
|
|
<command> has X_DX_AUTO_LOAD exported. Such a command should probably
|
|
only have one object file, one CODE segment, and no other initialized
|
|
segments.
|
|
|
|
<address> is calculated to be a page boundary that causes the linked
|
|
object file in question to end somewhere between $AF00 and $AFFF.
|
|
|
|
od65 should be in the same location as <command>
