Gunstar Super Heroes / Gunstar Future Heroes - status bar has graphical glitches

[YaketyJoe]

OS and Version: Windows - mGBA version 0.7.0 - released Jan 26, 2019.

In the games "Gunstar Super Heroes / Gunstar Future Heroes", the top energy bar has layering issues, causing graphical glitches. Part of the game goes over the weapon icons, when it does not in real hardware.

This issue clearly happens on first boss and on the second level. Please see images below:

Please provide a savestate.

Sure, here is a Save State, from a No-Intro rom:

fwiw this game is massively exceeding the scanline cycle limit for OBJs and expects OBJs beyond that limit to get discarded. implementing this will fix the issue.
there still will be small cut-ins at the bottom of the status bar, but those appear to happen on HW as well.

Strange, I already implement the cycle limit for OBJs.

That's strange then. I've only checked the first stage until the first boss so far which has the same problem as NanoboyAdvance had until recently. Implementing the cycle limit fixed it for me.

[fleroviux]

Just a wild guess: are you maybe rendering OBJs in reverse order (127 first, 0 last)?
That's something I changed recently and reverting that change Gunstar Super Heroes breaks.

Looks like my sprite cycle implementation was buggy! Thanks for the help @fleroviux.
