Please provide any additional information below.

What steps will reproduce the problem?
1. Open Emulator
2. Select Pokemon Gold or Silver or Crystal
3. Go down stairs. (If this is successful, continue out the door of your house. 
the chance that these are both successful, then you are really lucky, but it 
won't load going in or out of any of the other houses.)

What is the expected output? What do you see instead?
-The next room, instead, i am presented with a blank screen of a sort of creme 
color)

What version of the product are you using? On what operating system?
JGBE V752 (most recent) on a mac

Please provide any additional information below.
I can't figure out how to avoid the error, and, all i can find, is a quick save 
right outside the door to the next room, and you have to try again and again 
and again until it finally decides to work, and it's only a quick fix until the 
next room, and it working the first time is about a 1 in 20 chance, if it's 
even that good.

I don't know what happened but the games will not load. The emulator itself is 
at issue, because the games will load on an inferior emulator. It seems to 
produce the coded commands.

The error message was:

File: Super Mario Land 2 - 6 Golden Coins (UE) (V1.0) [!].gb (MD5:
a8413347d5df8c9d14f97f0330d67bce)

What steps will reproduce the problem?
1. Get a rom from a shady rom website
2. Try to load rom in JGBE
3. Fail

What is the expected output? What do you see instead?
A warning could be issued, but ROM should be executed. Now the rom will
simply not load at all.

Commonly this happens when a ROM has for example 16 banks, but only the
first couple of banks were dumped (or perhaps the rest did not contain
usefull data). JGBE will fail to load such ROMs because it expects all 16
banks to be present in the ROM.

What steps will reproduce the problem?
1. execute "jgbe.jar"
2. wait...
3. voila, crash.

What is the expected output? What do you see instead?
The emulator should start. Internal error message.

What version of the product are you using? On what operating system?

Please provide any additional information below.
i fails to load the emulator itself and it claims to be a problem in the 
emulator its self and that it should not happen

What steps will reproduce the problem?
While trying to play 'Perfect Dark', in the second room of the first 
(trainings) mission (the first room with a guard), the guard may disappear 
while he is chasing Joanne. There does not appear to be a way to make the guard 
reappear. Because the door to the hallway/shooting gallery stays locked until 
the guard is taken out, this results in halting game progression.

What is the expected output? What do you see instead?
The guard should not disappear. The guard does disappear.

Please use labels and text to provide additional information.
Certain sound effects appear to be missing. During the initial credits 
(Lasering f the Nintendo logo, RARE logo) there is no sound. Also during the 
mission briefing the text should be spoken (voice-overed) by the instructor and 
Joanne.

What steps will reproduce the problem?
1. save state
2. no white text saying saved state
3. try to load state and it says it loaded state but it does not do anything

What is the expected output? What do you see instead?
to show text and saving the state so i can play big games were it is ipposible 
to complete without saving
it not saving

What version of the product are you using? On what operating system?
jgbe v0.4.2 windows 7

Please provide any additional information below.
there is no error and it does not look like it saves or doing anything i can 
still load the rom (prop with 7.5.2 were it does not load)

Also; for some reason the bios is not always run on reset, even when a bios
is selected (even for mono roms). Instead the stub is used.

1. Start JGBE on a computer that has it's C:\Users\username directory locked
2. Attempt to enter keybinds
3. Attempt to open a ROM

What is the expected output? What do you see instead?
Keybind config screen opens as expected.  Upon finishing configuration, the 
user is alerted that their keybinds could not be saved.  When clicking the 
"Load File" button, there is a short pause before the file selection window 
opens.  Upon selecting the ROM, the emulator spits out the error shown under 
"additional information" below.  There is no setting to change the directory 
that JGBE uses, nor is there any warning to the user about what is happening.

What version of the product are you using? On what operating system?
