No game is loading so far

[Gamer123]

Hello! I am new user to Dolphin. I have tried playing two games so far, Super Mario Sunshine & Mario Kart Double Dash. When I launch a game, the BIOS show just fine. But then the framerate drops to 0 and I get a black screen. I'm not sure what setting would be responsible for the black screen. I am playing off of the ISO/GCM file.

I've attached a screenshot of the black screen in case people need to see.


My specs are:

Windows 8.1 x64
AMD A8-5500 APU 3.2 GHZ (quad-core)
Geforce GT 630 2GB
8 GB DDR3 RAM
Using Dolphin 4.0

I appreciate any help!

Corrupt GCM file.

Try skipping the BIOS. I've experienced some issues with it between different games.
Config > Gamecube > Skip BIOS

Also, you're most likely going to run into some speed issues on heavier load games because your CPU doesn't have great single-core performance.

Or you have a wrong IPL region file (trying to run a USA game while booting with the EUR BIOS file).

I appreciate the help so far, unfortunately, I haven't figured it out yet.

1. I've tried three more games to see maybe if it was the GCM file, and they all do the same thing with the FPS going down to 0.

2. I've tried skipping the BIOS, but still get a black screen.

3. All of my games are USA based; is there some option that may be messing them up based on region?

Any additional help would be appreciated!

Which graphical backend are you using?

It's always possible that however you dumped the games wasn't correct (e.g. bad disk reads while dumping, bad file writes when copying dumps to SD card or USB drive). There's only one way to be sure. Grab a utility that can generate MD5 hashes for files (google around, there are plenty of free ones online), then compare your MD5 hashes with the hashes of verified dumps on sites like GameTDB.com. If your hashes do not match, your file is not 100% byte-for-byte correct, and you should redump/re-rip your games until the hashes do match.

I'm having the same problem using 4.0.1 and 4.0. I tried downloading 3.5 and when I run my game there I get

"backpatch - no support for operand size 1
error encountered accessing emulator address c2339f3d
culprit instruction:
movzx eax, byte ptr ds:[rbx+rcx]
at 0x124fac34"

Which game?
Only this game or all/other games?
