Altstore: Delta 1.2: NES roms loading to black screen

[jsbobatea]

Describe the bug
When loading any NES rom, it produces a black screen. I attempted to load one game from my save state (CV 2: SQ) and it loaded a black screen, with looping audio.

To Reproduce
Steps to reproduce the behavior:

1. Download any legally owned NES game rom.
2. Import to Delta.
3. Load game, controller skin displays.
4. Black screen, no gameplay or audio.

Expected behavior
When loading a NES rom, it should produce gameplay / audio.

iPhone (please complete the following information):

• Device: iPhone 11 Xs Max
• iOS: 14.1

Additional context and logs
I verified it is not my install, as SNES / N64 / GBA / GB all load without issue. NES worked prior to downloading the newest update (Delta 1.2).

I can confirm, recently my nes rom (smb) is loading to a black screen as well. The rom is dumped and was working with the previous update

I have reported this bug many times.

The bug was "fixed" only if you run first a Snes rom and then NES ROM. Or preview the game before running NES ROMS. I would love if this bug is fixed soon.

@ronaldsb Thanks for the workaround, can confirm it worked by loading SNES rom first, then NES. Very weird bug. Hopefully we see a fix. I may dig around and see if I can spot the cause myself.

Please please 🥺

Riley may know how to fix it because he just fixed in the last build but only running first a Snes Rom. He just not fixed running only NES roms.
