A few things to note about reporting: - Please use (F12) to make a snapshot of the game. This will show precisely what is being shown on screen. Print-Scrn copies are useless, especially for graphic bugs, especially when they are 'post edited'. Your description should be enough to signify what is actually wrong with the presentation. - Also, we only test with the official Softlist version of a game for ease of testing. This is to guarantee a standard method. You don't need to attach the game, simply state the game (setname) which doesn't work in the game (coleco). In this case, the setname is (frogger) As regards to the green squares, they have been there for a long time and this bug was in the old BugZilla database, having posted it there I can confirm that. Also, certain coleco clones do NOT have this bug with Frogger. Have you tested other clones? |

I think this will need pixel timing accurate tms9928.c emulation =( |

ok, interrupt timing is cycle accurate now, which happens to fix this glitch |
