So this is an odd issue, see, I'm using the re-translated version of Breath of Fire 2 (let's be honest, the original version is a garbage heap in the translation department, and the new HUD looks pretty sleek), the issue is that the top line of the HUD is half missing, and the half that does remain, flickers constantly in battle. I don't know exactly what the ROM patch does to the game, or how it affects how the resolution is affected, maybe it's some kine of pseudo hi-res going on, not sure. But it's quite distracting, and looks quite abnormal.
Firmware: 1.8.0 sa1 revision 6 beta
Super NT: firmware version 4.5
Earlier versions of the SD2SNES firmware yield the same results.
Normally, there should be a black line going across the entire HUD, but it's missing about half of it. I highlighted the problem in the attached image:

I can't seem to reproduce this on Snes9x 1.55, which is aimed at fairly high accuracy, so I'm not sure what's going on. Any insight is appreciated, thank you.
Edit: I stand corrected, that black line isn't supposed to be there at all, running it on Snes9x 1.55 and well, it's supposed to look like this:

Either way, something is amiss and I hope it's not a serious issue, but again, it is distracting on the screen.
