You basically have three sections:
########################################
Hardreset:
If enabled (HARDRESET = 1) the system will automatically do a BIOS reset when launching a game, it's like always launching a game with L+A. This will make the "Gameboy Advance" Logo appear when launching the game, a few games need this reset to work. I would recommend having this setting enabled but you can disable it (HARDRESET = 0) if you want.
########################################
Keyset:
Consists of 1 setting (USE_KEYSET) and 3 subsections ([SLEEP],[WAKEUP],[RESET] and allows you to define your own button combination for sleep mode, waking the GBA from sleep and reseting to the EZ-Flash IV menu (Please see the note in the next section)
If the setting is disabled (USE_KEYSET = 0) the EZ-Flash IV will use the default button combinations for sleep (L+R+Start), wakeup (Start+Select) and reset (L, dpad up, B). If enabled (USE_KEYSET = 1) the system will use the button combinations you define in [SLEEP]. [WAKEUP] and [RESET]. For example:
Code:
[SLEEP]
Button_L
Button_R
Select
Will make the GBA sleep when you press L+R+Select
Code:
[WAKEUP]
Start
Select
Button_L
Will make the GBA wakeup from sleep when you press Start, Select and L
Code:
[RESET]
Button_L
Button_A
Button_B
Select
Will make the GBA reset to the EZ-Flash menu by pressing L,A,B and Select. Note that you shouldn't use the R-button in the reset combination as that is used by the EZ-Flash to initiate the Firmware update on boot. Depending on the cartridge this would result in the firmware being flashed whenever you use the rest.
########################################
Global Softreset and Sleep (GSS):
This en- or disables the above mentioned functions of resetting to the menu or putting the GBA to sleep.
Disabling GSS (DISABLE_GSS = 1) will obviously disable these features whereas enabling it (DISABLE_GSS = 0) will allow you to sleep or reset.
The GSS patching used by the EZ-Flash team, however, greatly decreases game compatibility, a lot of games will crash, freeze or glitch out with GSS not disabled. If GSS is enabled (DISABLE_GSS = 0) you can still launch a game with GSS disabled "on the fly" by launching them with the button combination 'L+B' instead of simply pressing 'A' in the EZ-Flash Menu. You can, however, also enter the game ID in the keyset file to always have the EZ-Flash Menu disable GSS patching for ROMs with this game ID.
for example
will tell the EZ-Flash to always launch the ROM with the game ID 'BKZX' (Banjo-Kazooie - EU Version) with GSS disabled as this game will otherwise not work.
