Seeprom Viewer is a Homebrew Channel Application that displays the contents of your Seeprom onto the screen. The display will be shown in a Hex-Editor like fashion. Press the Home/Start Button on your controller to exit back to HBC at any time. The app is made via Inline ASM. The part of the source (within /build/main.s) for reading from the SEEPROM was originally made by Team Twiizers in C. I rewrote/optimized it in full ASM.
Copy of the original C code plus the GPLv2 License are contained in the orgcodelicense.zip file.
For a regular binary download of the HBC app, go to the Releases tab/section. If you instead want to compile from source, keep reading.
How to Compile & Run:
Requirements: DevkitPPC on your computer, HBC on your Wii Console. The version of HBC must be 1.1.0 or 1.1.2. If using any other version of HBC, this app may not work.
Using devkit's PPC Assembler within binutils, compile the main.s to object code (named as main.o). View the compilation example below for exact details. Then simply run make on the makefile to compile the dol file. Rename the newly created dol file to boot.dol. Place boot.dol in the seeprom-viewer-hbc directory. Place that directly in the apps directory of your SD/USB device. Launch HBC, launch the app.
Compilation example (Linux):
1: cd /path/to/your/binutils
2: ./powerpc-eabi-as -mregnames -mbroadway /path/to/Seeprom-Viewer/build/main.s -o /path/to/Seeprom-Viewer/build/main.o
3: cd /path/to/Seeprom-Viewer
4: make
