Illegal HW Read32/Write32 cd0068XX error on latest builds

[mbc07]

So, after I updated Dolphin to 3.0-362, I started to get a lot of errors like this on Dolphin's log, not a big issue, however, I noted that the emulation starts to get progressively slower, on my tests with Zelda Wind Waker, it was running constant and stable at 30 FPS when I booted the game on Dolphin and after around 20 minutes of playing, the max FPS that I get (in the same area that I was running at 30 FPS) was something like 13-15 FPS...

All my settings are the default, except audio backend (XAudio2), and some video settings (OpenMP Enabled, EFB Copies to Texture, fast mipmaps disabled)
< my computer specs are on my signature, issue occurring with 3.0-362 >

The errors that keep repeating forever on error log are these: (I would attach the log, but it is 50 MB in size)

Do you remember which revision the slowdown started in?

[mbc07]

I'll try to discover the exact revision because I just updated from 3.0-232 to the latest, so I can't confirm it now...
______________________________________________

The last working revision is 3.0-319, any revision after the Gecko branch merge (3.0-323) have this issue. Also, this is occurring only with GC games, Wii and WiiWare games are working fine...

I took a look at the code changed in that revision and nothing should have changed unless "Enable Cheats" is used. Do you have cheats enabled?

[mbc07]

Yes I have (now I'm asking me why? I didn't use cheats). Disabling "Enable Cheats" fix the issue (however it's a workaround)... Should I open an issue on Google Code?

Do you have logging enabled? If you turn off logging and enable cheats, does the game still progressively slow down?

[mbc07]

Yes, but the slowdown reduces a bit (dropped only 5 FPS during 15 minutes of gameplay, with logging enabled it drop around 15-17 FPS)...
