Buildroot Cross-Compile Tutorial

[late2theparty]

Sorry for the thread necromancy but is this what I need to do to get the Doom files I downloaded from Dead Phreak's other post + a Doom WAD to compile a TAR that will install on my LeapPad Ultra? I tried zipping it as a plain .TAR file with 7 Zip and it installs but crashes the tablet when I click the Doom icon and try and launch the game. Thanks.
