no algo is ASIC Resistant.
most algos had been made FPGA, even crytptonite ,HEFTY1 and prime-series
a single FPGA chip,
for x11,X13,prime,FPGA is much faster then any GPU,
for memory-hard styles,such as scrypt,crytptonite,it is the same speed,but only 1/10 power,
currently,the only algo that fpga cannot fight back is HEFTY1,FPGA expert proved,it is only 158K per chip,but 290x is 28M, 980 is 40M
so you know someone mining m7 cryptonite (xcn) with a fpga ? Not that it is particularly fpga resistant as the algo does 7 algo in parallel...
edit: you are probably talking about cryptonote
