unlock read speed should always be off for better compat same for any forcing or stuff like width and such.OK, now I’m having trouble with the European F-Zero GX [GFZP01] iso too. 1:1 copy with hashes verified against redump.org
I’ve completed the Ruby cup with no issues, but when I started the Sapphire cup the game starts freezing randomly. I tried disabling Progressive patch and unlocked read speed but it didn’t help. (First time I got to the 3rd track and the game froze halfway, second time the game froze about 15 seconds into the 1st track.)
I tried with and without unlocked read speed, but had the same issue. I have a USB 3.0 HDD so it should be as fast as the Wii’s USB 2.0 interface will allow. Also, the Wii’s SD card slot speed is limited (I have a 32GB class 10 card I think, but the read speed would probably be lower than that). Anyways I doubt it’s anything to do with read speeds.
everything off or auto except mc emu is the best compatibility, your hdd being 3.0 maybe that can be an issue, i bet if you use your sd card it will work perfectly, also you sure your iso is 1:1? md5 confirmed with redump?
