I was needing to put some fonts and textures into my elf file, and I did it in that way:
I took the original code of the font/texture loading functions and exchanged the fread()/fseek() calls to memcpy()/increment/decrement counter calls, using a counter to simulate the file position counter.
I used bin2c to convert the .fnt and .bmp files into a char array.
It worked great for bmp textures, but I wasn't so lucky with the fonts...
I didn't want to use romfs, and instead I preferred to use this method, that should work. (PCSX2 freezes when I try to use them :(, but work great with the modified texture ones... )
Look at the modified font loading functions, with the original parts commented:
