This is a rather strange glitch that I've encountered in the following ROM hack, located here: https://www.romhacking.net/translations/1384/
Specifically, the ROM hack from Ryusui's re-translation hack, has an odd behavior with the top-most line in the battle HUD. What's odd is I'm getting various results in how it's displayed. On the top of the HUD, it's showing about 1/4 of a black line flickering at the edge, tested on Higan Accuracy and a Super NT. But on Snes9x 1.55.2, the issue is nonexistent, and there's no black line or flickering of the edge of said line.
Snes9x 1.55.2 - no black line on battle HUD
Higan Accuracy - black line on 1/4 of battle HUD, flickering
Super NT/SD2SNES - black line on 1/4 of battle HUD, flickering
As you can see, Higan and the Super NT have the exact same results with the black line anomaly.
I'm running it on a Super NT, which uses FPGA hardware simulation and not emulation, so emulation should be pretty indistinguishable to a 2/1/3 2-chip model SNES, running of the latest SD2SNES revision and firmware. What I was informed on the Krikzz forums is that this is "normal SNES behavior" and would require someone, notably the author, to debug this particular HUD issue. My question is, if the real hardware does it, and cycle-accurate emulators do it, what options are there more that one can look into?
Thank you for your time, I certainly hope I'm not wasting anyone's.
