Some time ago, during our review of the Eightarc Fusion arcade stick, we made mention that, under testing, the Eightarc was faster than the MC Cthulhu chip from GodLike Controls. Apparently, this caused some worry due to the latter being one of the most preferred PCBs for custom and dual modded sticks. In response to this, Toodles, owner of Godlike Controls has conducted his own comparison test to verify these claims.
Unlike the original test, Toodles conducted his in real time and to remove possible human interpretation errors. He simply has two characters (in this case Ryu) perform a hard punch against each other and see who gets the counter-hit. To do this, he sets up two tests to allow him to activate the command with one button wired to both a Qanba Q4 RAF (which is what the Eightarc Fusion is based on) and a standalone MC Cthuhu PCB. With the first test, he uses a small custom board that separates the signal lines from the Qanba and the MC Cthulhu. To address any doubts of fairness, Toodles has provided the schematics as well as photos of this board to allow people to replicate the test themselves. Meanwhile, the second test has both boards directly wired to the button without a separate board.
The results of Toodles’ tests are quite different from ours – not only does the MC Cthulhu not lag behind the Qanba, but it is at times faster than the Qanba. During the first test (with the signal separator board), the MC Cthulhu beat out the Qanba 17 times out of 51 with the latter only beating the MC Cthulhu once. During the second test, with the button wired directly to both PCBs, the MC Cthulhu beat out the Qanba, while the latter won only twice. Again, to address concerns of bias, Toodles has provided the instructions for anyone to conduct the tests themselves. As for why our own tests gave different results, Toodles suggest that it could be due to a bad dual mod (as the dual modded TE in question, did have issues being detected by the XBox 360).
