@cool coyote, thanks for the answer, my "emulation" computer is modern enough to run Dolphin with a 1060 Nvidia card so I don't think it is the problem.
@Gingerjazz, I am relieved to see that I am not the only one with this problem, although contrary to you I have also the problem with older versions of Triforce for the other games (It was working back then and I don't know since when and why it is not the case now). Maybe you can tell me which versions you are using for FZero and mario kart GP 1 for example ?
@Hyperscorpio I don't want to blame anybody for the unstable state of the emulator of course. I have started using emus back in 1996 so I know how it works and never in the world would complain to an emu author for his work. Here it's just that I haven't found a solution despite searching the internet extensively about my problem and I wanted to know if somebody else had the same problem and found a solution. I will patiently wait for future versions.
