Hello!



I couldn't find any direct mention of this anywhere, so here I am. I've had this problem for a while, but have only recently narrowed it down to this. It turns out that an R4, specifically the "R4i Gold 3DS Plus," an r4ids.cn card, has nearly half the apparent read speeds of an original DS cartridge.



Below is a recording of scrolling through the bag in Pokémon White 2, one done on an R4, and the other on an authentic cartridge. I'm assuming that this is related to read speed due to the nature of having to load every item's image and description as the bag is scrolled through.







The MicroSD card I'm using in the R4 is a Sandisk Extreme that's rated at read speeds of up to 100MB/s. I have tried it on SD cards of varying speeds, capacities, and allocation sizes, and have gotten similar results.



I originally thought that it could be due to one of two things. One, that this was related to the R4 running in DS mode, as opposed to DSi mode with its higher CPU clock speed. And two, that it was due to limitations that are inherent of SD cards. These were both shown to be false when I tried running the game through TWiLightMenu++ and NDS-Bootstrap, which allow you to run DS games off an SD card. While running at the normal DS mode CPU clock, I was able to get the scrolling speeds of an original cartridge.



So, I'm curious about if this applies to all R4 models, or if it's less pronounced on others. I've attached the White 2 save file that I used in this test, and am hoping that someone can try the same scroll test on their R4 and post their results here.



Of course, these are just my own thoughts, and I'm not very knowledgeable about these subjects. I may be horribly wrong about all of this.
