I found some bad bits, but it doesn't change anything with the emulation. Plus1 locks up rightaway whether these bits are changed or not. I will look into it again when we get the Mattel games playable(these run on the same COP400 model)

certain bad: bitmap x,y=
- 687, 1325
- 875, 17

maybe bad: bitmap x,y=
- 1673, 2067
- 2798, 17
- 2844, 17
