have you patched the rom?

No I'm pretty sure I haven't. Do I need to?

it was part of the instructions so I would imagine so.

Sorry I downloaded this rom ages ago and I didn't get any instructions just the rom file. Can you please tell me where I can get this patch?

You wouldn't need to get anything. It runs pretty smoothly on 2.6a. Tried deleting the save and recreating it and try again?

I just deleted the rom file extracted it again and it worked..... weird. Thanks for your help anyway guys! ;)
