    In first words, very big thanks for mGBA! I was asking You some years ago about GBA emulator and i'm happy that finally You made it!

    But there are some problems with some games.

    Some are graphically turned for about 45 degrees, e.g. Boulder Dash EX or have turned some parts of screen e.g. Bruce Lee: Return of Legend have turned background. Some have sound problems, e.g. both Metroids. Some have other bugs, e.g. Magical Vacation have glow effects not masked and it's big glowing squares instead glowing attacks or glowing during level up.

    If You want i can test all my games which i have and give You complete list what's wrong in what games.

    I have to ask, did you copy over the original gameboy advance bios to the folder? ;)

    That fixed up alot of the bugs in games like Castlevania Harmony of Dissonance. :)

    Yes. it helps. Now some (not checked all yet) of these games working ok. I suppose rest should also work without problems.

    Sorry for too hurry bugreport, i should check with proper BIOS before nagging. ;-)

    You are fine. :) I wondered the same thing, but Kelly pointed out that the original bios has to be there.

    As Doffo mentioned putting in the original bios files fixes most of the issues with gfx/snd glitches. Pretty cool playing GBA games on MorphOS. Something I wanted for awhile but until mGBA came along there were not many good porting candidates.

    I just finished deeper check all games which i have for GBA and all is working fine with BIOS.

    But i have one question and found one minor bug.

    For GameBoy and GameBoy Color neither screenshots nor snapshots are not available. Also [TAB] is not working. Is planned to add at least sceenshot option and [TAB] wit screenshot option?

    And this minor bug is about saves in GameBoy (*.GB). When save file is created, four symbols (.GBA or .GBC) is removed and .sav is added, but in .GB it's still four letter. It means that last letter from filename (not suffix) is also removed. It can cause rare bug, e.g. for both "Game1.GB" and "Game2.GB" same file "Game.sav" may be ceated.
