Slowdown/Graphical Issues(Bugs Bunny in Double Trouble)

[Former user]

Original [issue 97](https://code.google.com/p/genplus-gx/issues/detail?id=97) created by Icedus on 2010-06-08T05:08:29.000Z:

What steps will reproduce the problem? 1.Play Bugs Bunny in Double Trouble 2.Choose the "Bully For Bugs" level 3.Keep the bull on-screen and try to have it launch you in the air to get the dynamite

What is the expected output? What do you see instead? Whenever the bull is onscreen, the game experiences very noticeable slowdown. Sometimes, while the bull is onscreen, the screen gets filled with garbled graphics for a few frames. No slowdown occurs on real hardware at this moment. This can also happen underground, near the lions. I haven't played the game enough to see if it happens elsewhere, but it's possible.

What version of the emulator are you using (official, SVN revision,...)? r457

Please provide any additional information below (Video settings, Console region,...) Emulator settings are at their defaults, Wii region is NTSC-U and the game region is set to Automatic (USA)

Indeed, there is something going wrong with the screen resolution I think. Weird.

First time I ever saw this, the game is actually switching from H32 (256 pixels) to H40 (320 pixels) resolution modes during Vertical Blanking then back to H32 on line 0.

I bet the problem is coming from this and the way genplus-gx handles switches between those 2 width for texture rendering (frame are skipped because of resolution changes and graphics got bargled).
