Batch Converting GBX & GBC to GBA for EZ4

Got my EZ4 yesterday so I've been playing around with emulators...

Came across a YouTube Tutorial which pointed in the right direction;



I got "Goomba Front (Color)" from the supplied link: DOWNLOAD

I didnt want convert games together and found the App tedious,
So I got the "EmulatorFile.gba" and combined the emulator with
GBX & GBC roms by command line;

SINGLE CONVERSION
Windows:

Copy /B EmulatorFile.gba+gamename.gbc gamename.gba​

Linux:

cat EmulatorFile.gba gamename.gbc > gamename.gba​

BATCH CONVERSION (Linux)

for i in *.gbc
do
echo EmulatorFile.gba | cat - "$i" > "${i%gbc}gba"
done​

Obviously for GBX you would change the extention from .gbc to .gb
It doesnt take long at all to convert all the roms to .gba

Next up I downloaded "ezgba v0.2.0a-2" from here: DOWNLOAD
I used EZGBA to batch all the new files over to the MicroSD Card with default settings


Adding Splash Screen to GBX & GBC roms

I would really like to know how I would go about adding a splash screen...


Batch Converting (Sega) SMS & GG to GBA for EZ4

I downloaded "SMS Advance v2.5" from here: DOWNLOAD
The App works fine if you want to do each game one at a time,
I tried using command line to add the emulator "smsadvance.gba"
but the resulting files do not work, I'm not sure what I'm missing


Batch Converting NES to GBA for EZ4

I downloaded "PocketNES 6-13-2012" from here: DOWNLOAD
Again tried using command line to add the emulator "pocketnes.gba"
but the resulting files do not work, I'm not sure what I'm missing
