Bug Reporting

Well I tried out this emulator for the first time today. The 1.4.1 release seems to have trouble reading my inputs. Sometimes when I press a button, it holds that button until I press again. Sometimes it ignores my input all together. This becomes very evident when you e.g. hold right, let go but see that the input is still "on". When I try and frame advance it's the same problem, sometimes it skips 100 frames and sometimes nothing happens, so it's not just ingame inputs. I tried out the 1.4.0 release instead and it doesn't seem to have the same problem. I'm using a 32bit win7 Fujitsu Siemens Esprimo Mobile and I played Sonic Blast for the GG.

There is very low FPS and sound lags/stutters in SGB mode; some games(ex. Metroid II - Return of Samus (W) [!] & Donkey Kong Land (U) [S] [!]) are even glitched. Does it mean I need to change the sgb.sfc? I'm using Super Game Boy 2 (Japan).sfc.

SGB is very very slow to emulate, probably the slowest system in bizhawk at the moment. There's probably nothing wrong at all.

Are the glitches in Metroid II and Donkey Kong Land normal too?

Bizhawk uses bsnes/higan core for snes, which is what is used for SGB emulation. The same graphical problem are present when using Higan to emulate those games. So in this context, yes it is normal.

In the SVN number r4679, I think the disksys.ROM file is using a bad SHA-1. I have went about checking the various SHA-1 hashes of the disksys.rom files I could hunt down and I got a LOT of: 57FE1BDEE955BB48D357E463CCBF129496930B62 Is it a bad hash being verified against or am I getting bad dumps? I did manage to find the "Bizhawk verified" version as well, but only once. Is there a third party tool I can use to verify the ROM file?

I think there are two different revisions of the FDS bios? The one I built and tested the FDS mapper core against is 57fe1bdee955bb48d357e463ccbf129496930b62; offhand, I don't know where the other one is from. I will look into it.

The other "ROM" I am having trouble locating is the Super Gameboy for SNES (SGB.sfc) SHA-1 for the GoodSNES ROMs I have (all): Super Game Boy (J) (V1.0) [f1].smc C539274B7AACA7DBF06AE3F841CCD2E2BBFC7F64 Super Game Boy (J) (V1.0).smc 7F87BA96F22F8FD90080A86CF81FB00A76BA30DB Super Game Boy (JU) (V1.1) [!].smc D8BB29AC68AB559FDFACA564F80963E45EBBDC20 Super Game Boy (UE) (V1.2) [!].smc E15F1C815E97D61C04C732A5D04F13092ACF55D8 Super Game Boy 2 (J) (V1.16) [!].smc EBC21925110F73B6DE6439D2081460FFF0F5EEE5

The Game Gear controller configuration menu is set to the Master System controller configuration menu. Game Gear ROMs do seem to load and play correctly. Loading an MSX1 ROM causes Bizhawk to load it as an Intellivision ROM. MSX2 ROMs will not load (No core found) which is the expected behavior. Compressed GBA ROMs are not automatically loaded if they are the only file in the archive. All other ROM types I tested (GBx, Genesis, Game Gear, Master System, N64, NES, SNES) will load with out asking which file in the archive so long as there is a single ROM in the archive.

The columns in RAM Watch are always assumed to be "default" when loading from a .wch file, so if you manually reorder the columns a lot of data will be in the wrong column when you load the file. As best I can tell the reordering is preserved by the program, but it doesn't pay any attention to what the "correct" column is when filling it with information. Example: If I reorder the Diff column to be first with a few values, everything is fine. Close the program and reopen it to find that Diff is still the first column. However, adding any watches will cause them to use the default numerical ordering of columns; so now the Address will appear in the Diff column and everything else will be a bit wacky too. Just a small usability bug, but thought I'd bring it up nonetheless.

I am aware of the major GBA bug; it's not a big deal to fix, but I haven't done it because that core has some showstoppers in it and isn't going public any time soon.

Bug: The Dual GB XML does not want to open any archive file. It will open extracted GB/GBC roms. And will run properly. Bug: Any screenshots while Bizhawk is running in dual GB mode, comes out black. Properly sized, but black. Bug: Pokemon Red/Blue has a minor graphical error during the Name Entry screen. The End icon, is garbled. Other Pokemon games do not have this issue. Bug: Discohawk has issues with this CUE file. I think it may be the blank lines at the end of the file.

Though, I am unsure if discohawk is failing due to the Bin/Cue or just the Cue file.

BizHawk 1.5.0 doesn't recognize my disksys.rom even though it's in the Firmware folder. When I right click the FDS Bios in the Firmware dialog, click Set Customization, and double-click my disksys.rom, an error message appears:

Closing this dialog box causes the NES section to vanish from the Firmware dialog. After that, clicking any of the three buttons at the top of the dialog or closing and reopening the Firmware dialog brings up the same error, every time I bring up the Firmware dialog, until the BizHawk config file is deleted and replaced. EDIT: Also, this error message appears whenever I try to open a Game Boy color game:

GB games work fine for some reason though. And you can play back a movie, but it refuses to start the movie over from the beginning or even reboot the core.

I can confirm the GBC Bug. I loaded a Saturn Bin/Cue (Daytona USA MK-81200), when I try and reboot the core or open any other ROM or try and close the emulator I get:

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.

Then I am stuck with the Emulator running the game.

I also have several, and none of them are the same as yours. This is why you have the ability to set whichever file you want to satisfy the firmware. We've only validated the behaviour of the SGB with one firmware version, and thats the version in the firmware manager subsystem. FWIW, I have that labeled as "Super Game Boy (World) (Rev B)". If you've validated another super gameboy as working fine with it and want us to add it as an acceptable alternative, as long as you're sure it's an unmodified actual rom that exists in the world (good* isnt always accurate) then propose it. But I suspect one of our sources is largely junk. We should probably check to see whether the OCD higan community has a recommendation.

There are two FDS bios versions. One is from the actual FDS, and the other is from the Twin Famicom, which has a little bit of tweaked out graphics but shouldnt function any differently. See here for details http://tcrf.net/Family_Computer_Disk_System . As of r4837 they'll both be detected.

I wasn't able to reproduce the black screenshot bug, but I may have fixed it anyway. Not sure about that cue file, maybe zero knows. Can you explain your problem with dual GB xml in more detail?

Bugs which are pretty clearly emulation errors in c++ cores we've imported from other projects should get addressed to the author of the original core, if youre able to determine whether this applies.

I compressed my GB ROM files. In this case, 7-Zip. The Dual GB XML mode will not open a 7z file or anything that's not anything that's not a GB/GBC ROM. If I open a 7z file normally (Open ROM) Bizhawk works just fine. I will continue to test and break Bizhawk. If anyone is having trouble with the SGB mode, you need the UE ROM.

Hmm... I've tested archive loading before. If you take the following xml file: pastebin and put it into an archive container with a file named "Legend of Zelda, The - Oracle of Ages (U) [C][!].gbc" and "Legend of Zelda, The - Oracle of Seasons (U) [C][!].gbc" then it should load properly. Does that not work?
