[SOLVED] Scrambled Title Screen after jumping banks

[+Gemintronic]

Is there any common cause for a scrambled Title Screen kernel display?

 

I'm working on a game that:

 

1. Jumps from bank 1 to bank 4 for the title screen and music.

2. Jumps to bank 2 for in intro screen

3. When it tries to jump back to bank 4 the title screen gets reversed and scrambled.

 

Any ideas? Please note I'm only guessing that bank switching is a factor. In all honestly I'm not sure WHAT the typical culprits are in a scrambled title screen.

Try setting REFP0=0 and REFP1=0 before you jump back to the title screen.

That was THE solution. Many thanks! Maybe this is a big enough gotcha to document on R.T.s reference page?

I should probably just do the same in my code. I have a DPC+ bug fix I need to release too, so I'll add it in
