Turok: Evolution (GBA) Query

[Bananamonkey]

Hi!

Jeez, feels like I'm starting to be quite the regular here but okay, if you can still put up with me here we go: so I'm playing Turok: Evolution (GBA) on VisualBoyAdvance and I'm up to the part where you fight the first boss (I recommend this game for anyone who enjoys a highly cerebral storyline) and this message box pops up whenever I defeat the boss. Here's the message: 'Unsupported BIOS function 1e called from 080362aa. A BIOS file is needed in order to get correct behaviour.' The game then freezes and I have to close the program. Any suggestions on how to fix this?

you need the bios to properly emulate the rom.I can't give you a link for a GBA bios,but you can dump your own.
but you can try changing the savegame type to 128kb flash.
