That was a close one! It tries to launch Minecraft, but crashes anyway... It seems like that it's now impossible to run MC with mesa, but if it actually is possible then there's something wrong with my laptop or Win 98 installation... In case my installation is in fact fine then I'm gonna move to another laptop I have, a Fujitsu-Siemens Amilo Pro V3515, even though I don't know if it comes with Win 98 Drivers too, by the way, I tested it with XP and it runs up to 1.12.2 without mesa
