Got it to work! Sonic pokemon Z with a 4gb SD.raw.

Here's what I did:

Install an iOS 36 wad in dolphin.

Delete the config.dat file( I suppose this is to make gecko work on Wii? It just seemed to make gecko not even start. And minima launcher won't apply the code it seemed. I was playing vbrawl.
I realized my brawl minus so.raw only had codes and minusery(their custom pf folder path ) so it did not need the config.dat for dolphin.

Brawl minus does not need a gameconfig.txt but SPZ does which is apparently used to add more lines of code?
So I did not have that the first time, trying to me it look like brawl minus sd.raw which resulted in gecko saying too many SD codes found and couldn't apply them.

Thanks for the help and I hope someone finds this useful to play this as it looks really fun, or any other brawl mod. If someone has better explanations on these files that would be helpful in understanding.

SdHC is supported because I can see the different intro and main menu but I cannot get into the CSS.

Oh ok I think I was using the wrong boot.elf. I'll try again.

Edit: I get an error on startup, invalid read 0x00000000c, PC= 0x80e4ee9c or something like that. What dolphin version are you using? Sorry for the trouble.

Should I add the SDHC expansion code as now it just loads vbrawl. I can't seem to load gecko either only minima launcher works when I load it's boot.elf file.

No wait, it loaded before. I'm starting to think PM and dolphin just do not mix welll as I have tried other PM related hacks that also did not work.

Yes I put brawl minus on an SD card and that worked so I know SD cards should work. Is it simply copy all contents to the root of the SD card?

I tried that as well and it still crashed with Sonic pokemon Z, also downloaded the SD.raw you put in the comments of a YouTube video and it still did not work.

I am having the same issue as the previous poster concerning dolphin.

Super+ also crashed when built as an iso. Odd that PM worked when built and this did not. It crashed on startup.
