3d Bonus levels in Sonic 3 in Sonic collection is unplayable

[drhycodan]

In Sonic 3 and Sonic and knuckles that's part of the Sonic mega collection, the 3d bonus stages keep repeating the same animation, therefore keeps you from obtaining any of the chaos emeralds.  I tried setting EFB to RAM and XFB and safe texture cache and the problem still persists.  I don't remember if the Virtual console versions suffer the same issue, but I'm 99% sure it does also.  Both video backends suffer from this.  Can someone please fix this as Sonic 3 and Knuckles is one of my favorite childhood games.

It requires a more accurate CPU pipeline. You can download this build, https://dl.dolphin-emu.org/prs/pr-1798-dolphin-latest-x64.7z go to advanced, and overclock the CPU until the glitches disappear. This is a work-around, not a legitimate fix.

Try this build and set texture cache to safe.

thanks, why hasn't pr 1316 been merged yet? It seems to fix this just fine.

It breaks other things.
