>>> not unless you have rom version 9 and you want it to crash all the >>> time!! id stick to os85! >> My ti-85 rom 8 used to crash when running Usgard, but it was because of a bug in patchrom.85s. I got a new version from another site (sorry, don't remember which) and then it worked all fine. Many of my rom 10 friends run Usgard too and they have no problems either. Kasper
