Welcome to The Minecraft Recreation Project. A media preservation project that recreates all missing released and developer builds of the game Minecraft
b1.5_02-dev, pre b1.5_02 labeled b1.5_01 ingame where you spawn with the map (the current b1.6 test build with tweaks)
b1.6-dev - you spawn in the sky dimension (current tb2 with tweaks, LIKELY all these above dont have advanced opengl)
and the beta 1.6 testbuilds i suppose are all advanced opengl by default and tweaks, they all have chests on startup so you can test all items rendering
(this is still work in progress)
