This Arduino sketch can write Nintendo Power SF Memory cartridges without an external clock source like the Adafruit Clock Generator.
|
||
|
|
It also uses the Arduino Serial Monitor instead of the OLED display and buttons.
|
||
|
|
Copy the rom and map file to the root directory of your SD card and make sure that the filenames are below 8 characters in length.
|
||
|
|
|
||
|
|
Configure the switches like so:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
First send "8" to switch the cart to "hirom all" mode. Check that it did succeed:
|
||
|
|
(8)HIROM ALL 0x04
|
||
|
|
Success
|
||
|
|
2A 4 2A 2A FE 61 A5 0
|
||
|
|
In case it failed close the Serial Monitor and switch the Arduino Mega off and on again and start from the beginning.
|
||
|
|
|
||
|
|
Next send "q" to unlock the write protection:
|
||
|
|
(Q)Unlock WP
|
||
|
|
Success.
|
||
|
|
2A 4 2A 2A FE 61 A5 0
|
||
|
|
|
||
|
|
Before you write anything you should always do a backup of your rom and mapping.
|
||
|
|
To flash something new you need to erase both the flash and the mapping first before you send the write command.
