Iridion II lockup (bgm still playing)

Hi there, I just discovered an emulation bug in:

Â

Iridion II

(Europe) (En,Fr,De)

CRC32=57930c6a

SHA1=661442c24404cc0727e4343f9ce570c87c797661

MD5=ba5048bbfb02ebe3874b8ce1b6318ce4

Â

Level 1 (the one after the training level)

Some seconds after first boss appears, pressing the 'A' button will lock up the game, however, the bgm will continue playing.

Â

From the beginning of the level or so until that occurs, I repeatedly get the following messages:

Illegal halfword read: 0400004c at 08020572
Illegal halfword read: 0400004c at 080212aa

Illegal halfword read: 0400004c at 080214a6

Â

The first time, I got

Undefined ARM instruction 1d085b42 at 04560808

while the game locked up, but I can't reproduce it again.Â

Save state attached.

Hmm...perhaps I should go and find my BoF2 save states again. It has the same problem, although I always thought it was due to the cheats I was using cuasing some sort of corruption.

A castles starts exploding and the sound glitches and the game freezes and that's that.

You should be able to get rid if any cheating influences by disabling cheats, doing a game ("battery") save, and loading from that save (cheats still disabled).

I am sure I tried that too.

Â

Darn, I can't find my save state at the moment...I hope I still have it somewhere.

I have been playing BoF2 USA release and never noticed anything even with cheats on [img]<fileStore.core_Emoticons>/emoticons/wacko.png[/img]/emoticons/wacko@2x.png 2x" width="20" height="20" />

It was the fairly late into the game...(I don't remember that much but you have monkey/monk/hand to hand + acrobatics guy in your party and you go to his castle home and the place gets tottalled and freezes) I guess it could have been the fault of an older version of the emu though.

Just tested Iridion, and i can't reproduce the crash.

So, it seems liek the save game I attached back then is corrupted when I download it now.

Â

I tested that bug with the current SVN891 and it's still there.

Â

As soon as the first boss arrived on screen, and I press the A button, the graphics freeze, but the sound keeps playing. If I don't press the A button, everything is fine.

Â

I'll attach another save statte which is about 5 seconds before the bug can be activated.

Â

Edit:

Hm, whatever I upload here gets corrupted, so I uploaded it to my FTP:

http://spacy51.sp.funpic.de/VBA-M/crash_saves/Iridion%20II%20(Europe)%20(En,Fr,De)4.7z

Â

Edit2:

Seems like I'm not the first one to find that bug:

Sorry, but i won't consider an issue brought about when the issue only exists within a game thats restored from a state.

Â

There is no issues otherwise, and i've tested the E rom with no apparent issues.
