| 49 | 49 | TODO: |
| 50 | 50 | - xexex sets up 0x20 as the VC? default value? |
| 51 | 51 | - xexex layers are offsetted if you try to use the CCU |
| 52 | - according to p.14-15 both HBP and VBP have +1 added, but to get correct visible areas you have to add it only to VBP |
| 52 | 53 | - understand how to interpret the back / front porch values, and remove the offset x/y hack |
| 53 | 54 | - dual screen support (for Konami GX types 3/4) |
| 54 | 55 | - viostorm and dbz reads the VCT port, but their usage is a side effect to send an irq ack thru the same port: |
