Using a bit of GLShim trickery, I've been able to get Minecraft PC booted by rebuilding LWJGL without GL 1.3-1.4 support, and am able to get to the Mojang splash before Java craps the bed and I sniff the pastebin off the console. Big thanks to Lumixbochs and Ptitseb, for getting me as far as I been, and I hope to get that much farther in the future. Any ideas on how to better do the things?
