Address	Length	Type	Description	Submitter
$0096BE	4 bytes	Jump (JML/JSL)	Modified by the Overworld Indicators patch. A hijack is placed here to clear the SRAM/BW-RAM entries the patch uses. [JML]	Erik

Address	Length	Type	Description	Submitter
$009B43	4 bytes	Jump (JML/JSL)	Modified by the Overworld Indicators patch. This hijacks the "Erase Game" routine to also clear the SRAM/BW-RAM addresses the patch uses. [JML]	Erik

Address	Length	Type	Description	Submitter
$009BCC	7 bytes	Jump (JML/JSL)	Modified by the Overworld Indicators patch. Modifies a load of 010A and then hacks the save game routine to synchronize the values from SRAM to their backup. [JSL]	Erik


Detail: Hijack
org $009BCC LDA $010A\|!addr autoclean JSL sync_sram_backup

Address	Length	Type	Description	Submitter
$009CFB	4 bytes	Jump (JML/JSL)	Modified by the Overworld Indicators patch. Modifies the load game routine to restore the SRAM backup. [JML] NOTE: this hijacks read3($009CF8)+33 instead if using Ragey's Overworld Expansion.	Erik


Detail: Hijack
if !ow_expand == 0 org $009CFB autoclean JML load_from_backup else org read3($009CF8)+33 JML load_from_backup endif

Address	Length	Type	Description	Submitter
$00FFD8	1 byte	Hex Edit	Modified by the Overworld Indicators patch. This value is the SRAM size in the original game, and it's changed to $02 to expand to 4KB of SRAM in case Ragey's Overworld Expansion is enabled. (Only does this if SRAM is 2KB, e.g. default value)	Erik


Detail: Edit
if !ow_expand == 0 if read1($00FFD8) < $02 org $00FFD8 db $02 endif endif

Address	Length	Type	Description	Submitter
$0485C5	4 bytes	Jump (JML/JSL)	Modified by the Overworld Indicators patch. Main hijack of the patch; draws the actual counter. [JML]	Erik

Address	Length	Type	Description	Submitter
$04E5F5	4 bytes	Jump (JML/JSL)	Modified by the Overworld Indicators patch. Writes to the exit table SRAM synchronizing when a level is beaten. [JML]	Erik

The Overworld Indicators patch was rejected, so the hijacks have to go, sorry.
