@spielvan it would be nice if you could provide a screenshot showing the broken graphics.

@baka0815 it's best to establish if it is a duplicate before gathering a bunch of info here.
Rest assured, this is not my first time responding to an issue and not asking was intentional.

@LoungeKatt I tried to fill in as much as possible, my apologies if I was not very objective, and my problem has basically been 100% related to graphic bugs, 90% of them in the background scenario, I do not have the related problem # 292 and # 431, how can I explain in Dreamcast 3D games Mortal Kombat Gold case scenario of Goro Lair, the player's closest part had to stay tarnsparente to be able to see the fight in the background, but is part of the layer without transparency, getting on the fighters and the backdrop background, in Soul Calibur (there are graphical bugs in the fighter's choice menu, and bug in the background scene in battles, perfect sound and speed), Virtua Striker 2 (bug in background and game score), perfect sound and speed) , The House of Dead 2 (Japan) (bug in the background and on the scoreboard of the game) ... by what I perceive it looks like a standard bug, which is repeated in several games.

@baka0815 I have all the images, from bugs to post, would I have a default server to post images here?

The content was fine. I just had to move it into the right spots. Either way, I cleaned it up for this one.

I have a feeling this is related to https://github.com/reicast/reicast-emulator/issues/1162 if it wasn't related to the other two. It may also be related to what is happening in https://github.com/reicast/reicast-emulator/issues/898

If anything, at least there are a lot of different games to test. Thanks for getting screenshots of all of them.

@LoungeKatt sorry, I thought that having the screenshots would help diagnosing if it's the same issue(s).

@baka0815 No worries. They ended up being needed, but the reason I held off was that if it was the same issue it would save the trouble of taking, uploading, posting, etc (especially on a data plan).

@LoungeKatt I'm going to enjoy what they were talking about Cannon Spike, I'm taking the European version to put on tests with today's reicast build.

Can we move this to one issue per problem, in gamedb? Thanks.
