Double Dragon (PlayChoice-10) There is a graphics block on the screen far on the right. (Ignore this report. Happen on the real machine. Video below.)

The orange lines on the pillars in Castlevania are also not a bug. Those pixels are just part of the background tile. It stands out a bit more in the RGB palette. It’s a subtler brown on the NES.

For reference here’s hardware footage on PC10 with the orange lines (it’s even in the thumbnail):

The status bar in TMNT flickers on real hardware on the NES, at least in rooms like this one with many sprites on screen. The PC10 version uses ROMs that match the US NES release so the behavior is likely identical.

By bad graphics “above” and “left” do you mean the garbage at the very top? That’s normal NES PPU behavior.

Both issues can be seen on real NES here for instance:

I can confirm the second stage glitches heavily on Captain Sky Hawk. It’s another Rare game with PPU/timing issues, presumably.

ok I will revert the two back to working. Thanks for letting me know.

Captain Sky Hawk (PlayChoice-10) stay as imperfect graphics.

I hate github, Anyway I change those two back.
