Expected results of H-Blank bit start tests

On hardware (Gameboy player) I always get Flip 1: 0x85 != 0x84. Is the test hardware dependent? Is it a typo in the expected results for the test?

I suppose another variable could be the flash cart I am using, but I only have the one and one piece of hardware, so no other data points. Currently my emulator implementation also gets the same result.

I'm getting 0x85 != 0x84 too on all my devices (GBA, GBA SP and 3DS with open-agb-firm), both with my EverDrive and EZ-FLASH IV.

I'm using a AGB-001 C/AGB-JPN-1 original GBA with EverDrive and a DOL-017 L-DOL-A-GP-1 Gameboy Player with the same EverDrive and getting Flip 1: 0x86 != 0x85, Flip 6: 0x3EB != 0x3F5.
Also after running the Layer Toggle video test I get Start: 0x451B != 0x1B after running the OAM Update Delay test I get Start: 0x3F1B != 0x1B. Running Layer Toggle 2 video test will fix the value again. Seems like those tests have some cleanup necessary.

I can confirm with my AGS-001 and Omega DE cart using test suite r88. First run gives 8/10, with the flip 1 and 6 failing with the same values. Running the tests above sets the start value to the different values reported until you run Layer Toggle 2 to set it to the correct one.
