Exception error handling?

[SubScorpion]

I keep getting this error on several games I've tried on the MVS multi when trying to enable cheats. Anyone knows what causes it and is there a fix? Neo board is an MV-1F, running unibios 4.0, with the latest firmware/menu in the cart.

Really? No one has any info on this, why it occurs or how to correct it? @Darksoft ?

I did. After doing the mod I had this problem as detailed here:

So I decided to try the cut trace mod again just for giggles and now the cart works but it's still giving me the exception error when using cheats on certain games. Any other ideas @Darksoft ?

Then you didnt cut properly before, I guess. Did you do a continuity test before? Regarding the exception error, that's because of the way in which the UNIBIOS works, that it takes longer time to return the control to the Program code than a regular BIOS would need and sometimes it produces those errors. IF you try those games with regular Stock BIOS, they should work properly.

The errors when running Unibios cheats are pretty normal, even when using original game carts. This could be just normal behavior.
