So, I softmodded my Wii using the letterbomb method when I got it a couple months ago, installed the homebrew channel, and put a few emulators on it, including FCE Ultra GX for NES and Snes9x GX for SNES. However, I've noticed something a bit odd... when playing NES and SNES games, heavy slowdowns tend to occur in various parts, especially when "too much" seems to be going on in the screen. For example, when playing Super Mario Bros. for NES, sometimes a scenario will occur where there are like 5 enemies on the screen at once, and the game will experience a massive slowdown until at least a few enemies leave the screen. Normally I would dismiss this as typical side effects of an imperfect emulator, except when running the same emulators on my old android phone (with only an 800 mhz processor), I experienced no such issues with NES or SNES games, so it's hard for me to imagine such issues would exist on hardware more powerful, like the Wii. Which leads to my question: The SDHC card I'm using is 16 gb, class 4 speed. Is it possible that I'm experiencing these issues because my SD card is too slow? Would upgrading to a class 10 eliminate the issue? Or is this just a side effect of the emulator itself? Any answers are appreciated! Note: I have made sure I have the latest versions of the emulators installed. I have also not played any of my other emulators (Genesis, PSX, N64) enough to really see whether they have similar issues.
