Then minecraft crashes before I even see the window open (the game, not the launcher). With the new launcher, it ignores the set appdata command, so I'm using the -workDir parameter instead.

My original setup was to set the appdata folder to a place on my USB so I didn't have to move all of Minecraft's resources and libraries (see this), but all of my profiles targeted C:\Temp\PMC so that the saves, logs, etc that were constantly being written to were put on a hard drive to preserve the USB. The Gameband does this automagically, but I'm dirt poor, so I made my own using the old Minecraft Launcher.exe. My goal is simple: run Minecraft from a USB without degrading it with excessive read/writes. I'm excited about the new Minecraft Launcher, and I'm hoping to put it to good use.
