M82 MT to RTYPE1&2 slight issues

[dave11674]

Hi guys
I converted a major title to rtype 1 and 2.
Both games boot up and play 99% ok. But I’m getting little lines on the screen. On both games.
Anyone done this mod and know why I’m getting these lines ?

Were these lines present before the dual-conversion?
