Dude.. what are You talking about?! there never were a "roulette glitch" first thing is the 1 and 5 keypress trick is only viable for dice gambling tables not the roulette/craps ones, and secondly you need to have sufficiently high enaugh gambling skill,requiremet for which i think was raised a bit in ET Tu compared to vanilla Fo1, as EtTu was never ment to be 1:1 experience when compared to vanilla Fo1. EtTu *is* a mod, and as such has liberities to edit stuff here ant there..
Simply put:
#1 You need to go to dice gambling (certain junktown casino tables, not the malteese falcon one in the hub-this one is craps/roulette-)
#2 You need sufficient gambling skill to have decent chance of winning per each bet tier [you can snatch regular dice off the shelf in gizmo's office and steal loaded dice from the tablegirl and plant the regular ones in one go, and you'll have better chance at winning, though skill investment is still a must]..
