History

#1 Updated by Nar over 2 years ago

Issue started with version 5.0-540 (Dynamic BAT, PR #4146). Activating MMU causes the FPS drop to 0 but music continues playing.
In earlier versions, you could complete the dungeon without errors, but then the game saved to a different .gci file with a different header.

This is definitely a valid issue of some sort, but the bisect is a false positive. MMU emulation just made the previously dangerous behavior no longer happen and crash the game instead, which is favorable.

I have no idea how to test this unfortunately.

Confirmed. This no longer read/write errors, but crashes thanks to MMU.

Funny, I just wanted to post this. I'm glad this is here. It's still a thing! I just had this error again yesterday with 5.0-9466!
Is there absolutely no way around other than using an old version of Dolphin?

#7 Updated by TarnishedBones 5 months ago

bad news is it looks like you have to use an older version of dolphin to beat the level. good news is it seems like if you beat it once on the old version you can come back on the newer one and it plays out just fine for that character.

#8 Updated by JMC4789 5 months ago

I tried that and on the old build, instead of crashing, it corrupted my save.

#9 Updated by DrevasBellmare 4 months ago

I created an account solely for the purpose of Posting this.

After Multiple tries with the usage of v.5.0-9719 Dolphin to no avail, I went and used an old copy i happened to have of v.4.0-9224 of Dolphin, and following the words of JMC4789, I created a Copy of my Save file under GC USA in a diffrent folder in case. And then tried it again. Not only does v.4.0-9224 run FFCC faster then v.5.0-9719, it successfully passed and saved at the mailmoogle with no troubles at all. No editing or whatsoever needed.

Hope that helps!

I'm glad I'm not the only one who ran into this, but I also can't believe it isn't fixed after this long. Guess I'll figure out how to edit my save so the game counts the level as completed.

#11 Updated by JMC4789 about 2 months ago

If it works in an old build, bisecting would help a lot. We've tried to fix it but there are a lot of games and it takes a lot of effort to debug an issue like this.

Any assistance from people who know how to play the game would be much appreciated.

#12 Updated by fantesykikachu about 1 month ago

I don't know what DrevasBellmare did to get it to work, but i just tried 4.0-9224 and I still get save file corruption, just like everything before 5.0-540 (after which the game just locks up). I then went back and tested 4.0.2, 4.0.1, 4.0, 3.5, 3.0, and I even dug up my archived copy of 2.0, and all of them have save file corruption, (and in case anyone asks I deleted all previous copies of dolphin between tests and moved my "Documents\Dolphin Emulator" folder somewhere else so i was always starting from a clean state between tests. So no, there is no working old build.

If anyone whats to try and fix this but doesn't want to play the game, I can provide save states and FIFO logs from both 5.0 and the latest development version, and if need be I can dump the assembly in visual studio, or GDB but with both of those I don't really know what I'm doing.
