How am I supposed to enjoy it without being distracted by that partially flickering line? It's distracting, it could damage my display (25" HP Omen display)? If it's been reproduced, why hasn't anyone reported it?
What's a good idea, me giving up on this? Or reporting it to ROM hacking? Because either way, not a damn thing's going to get done to fix this.
It might sound bad, but my recommendation is to play it on an emulator where it works properly, like SNES9x or ZSNES, since that's what this hack was designed and tested for and it has significant issues on real hardware. There are ports of SNES9x to various devices, so you'll have some choice of how you want to play it.
I know you aren't going to like that tho. But outside of someone finding a way to fix the hack, which is something I don't personally know how to do, there isn't a solution for real hardware.
There are other hacks that don't work properly on real hardware. It gets even worse and some of them require a specific version of a specific emulator to even work right. Like, you think those Auto-Mario hacks where Mario moves to music work on real hardware? Nope. They are generally designed and timed to work only on ZSNES . . .
I refuse to use Zsnes, because the garbage S-SMP emulation and speed hacks galore, haven't used it in years. The whole idea of me getting a Super NT and SD2SNES is to get the most authentic and accurate experience possible, no overhead, minimal lag, etc. If I wanted to do all that and not care about anomalies, I'd stick with Snes9x 1.55 (best version to date). You said yourself that this hack was tested on real hardware, and I believe those screenshots on ROM Hacking were taken from emulators. ROM hacks designed for emulators don't take into account cycle-accuracy but exploit weird quirks in the program, and it's a bloody shame. It's a shame that the same hacks on emulators run like crap on real hardware, goes to show that developers are lazy and only make hacks for the sake of hacks and have to sacrifice accuracy.
I refuse to use Zsnes, the developers abandoned it and don't really support it after 11 years. So Snes9x and Higan are really the only way to go for this game. But yeah, I'm going to get a mod to close this, this is going nowhere.
Snes9x and Higan both use Blargg's cycle-accurate S-SMP, something Zsnes will never have. I'm sticking to my Super NT for SNES, so, not happening.
