I almost had a fairly serious sense of humour failure getting the chainring bolts out.
Ended up with the allen key clamped in my worktable, chainset on top, outside face down so the allen key inserted in the bolt, then using all my body weight to hold the chain-bolt-nut screwdriver thing into the grooves so it didn't skip out, using an adjustable spanner to turn the blade of the screwdriver to back the nut out.
Got it out, straight in the bin.
SRAM chainring bolts ordered that use an allen key on both sides.
