No slowdown or frameskipping that I've noticed. Forced widescreen aside, the only weirdness I've noticed so far are these:
- Sometimes in
Luigi's Mansion, the music wouldn't start right away when entering the file select screen, and again when entering E. Gadd's lab after selecting a file. There would be a delay of two or three seconds before music started. Didn't happen every time, and usually seemed to happen when I did have Force Widescreen selected.
- There was a line of subtitles that didn't show up at the beginning of
Star Fox Adventures.
Otherwise it's been smooth sailing, and as I told Jorge on FB, the Wiimote+Classic Controller combo actually registers the analog presses of the shoulder buttons (regular Classic Controller only since the Pro revision removed these).
There are some other things that could be fixed, particularly with the interface. Pressing the Home button brings you back to the loader (in my case, Homebrew Channel) instead of back to the Nintendont startup, which is annoying having to restart it each time you load a game. Also, settings are universal, so you can't have saved settings for each ISO. It also froze for whatever reason when I selected a PAL ISO for
Luigi's Mansion, forcing me to actually unplug my Wii U (frightening; I always fear I'll break something). Did anybody know the PAL version for this game has a mirrored mode???
Here's something interesting: I played
Resident Evil 3 for a bit, which looks awesome on the GameCube except for one major problem: it's interlaced and blurry. What makes it better than the PSX version is the graphics being much less compressed and higher res, so you can actually read the text on signs; however, being that it's so blurry, I opted to play the PSX version on my PS3 upscaled to 1080p for my first playthrough this past summer.
Well, Force Progressive Scan really makes it look smokin'. Hard to tell from these cellphone pics, but it's much, much sharper now than when playing the disc on my Wii. Peep out the texture on Jill's face and the text on the sign.
