Huh, that's odd. I never get issues with my SD card, it works fine for me. I had an older SD card that caused Wii64 to stutter (Sandisk 8GB) but once I switched it to my new 64GB Sandisk it stutters less.
It's fast enough to where you shouldn't have stuttering with NGC games, just slightly longer load times. With Wii games, however, it will be noticeably slow, especially noticeable with games that stream video from the disc while playing it for cutscenes.
I would get stuttering in certain games like Mario Kart Double Dash. The stuttering is most noticeable during the intro video. When I used a USB SD Card reader all stuttering issues I had were gone (except in games that did it on the real GameCube that is).
I will record that part for you in a video and i will show you that it doesnt happens to me.
I noticed quite a bit of stuttering in cutscenes and longer load times with games like Rayman Origins using the Wii's SD reader. The SDXC card wasn't a cheap piece of crap, either. It was Class 10 and UHS-II. NGC games I haven't really noticed any issues.
Maybe the Wii U SD Slot is slower than the Wii's. Wouldn't surprise me. I would get stuttering every time on my Wii U with my Polaroid 64GB SDXC Class 10/UHS-I card. When I used the SAME SDXC card in a USB Card reader, the stuttering was gone.I will record that part for you in a video and i will show you that it doesnt happens to me.
This could be true because on Wii it's quite fast actually, if formatted correctly I get saves and channels installed on it to load much faster than on real NAND and I'm using a 32GB one.
If you send me your changes so far, I can take a look at it and see what's causing a bottleneck.
branched it to here:
I intentionally set it to NOT be thumb, it was thumb originally. If you need space then I'd rather just give the kernel more room (I planned for 1MB total anyways).
Is there a particular reason for not wanting Thumb? I'm not really too sure of the intracacies of Thumb vs. regular ARM code other than Thumb being smaller. I'll revert that, though I'm not too sure of what changes need to be made to increase the code size to 1MB other than the linker script. (I saw various other changes last time the code size was changed and I'm not sure how they go together.)
because of its nature thumb is missing quite a lot of instructions, especially on the older ARM version the wii and wiiu carry, so certain operations have to be worked around in some really weird ways in order to work, taking up quite a lot of extra ticks, a great example is everything regarding float, this ARM revision in wii and wiiu is missing a FPU. also jumping from arm to thumb and back always comes with some very weird extra code generated on the side which has to be executed every time and we need those jumps a ton on everything because of syscalls. I changed sizes not too long ago in this version, the files in question are kernel.ld and Patches.c.
