Small visual glitch in ALttP

[RichEsq]

When playing A Link to the Past, at the "Choose a File" menu, press right on the D Pad on a selected game file. An options menu will appear allowing the user to choose the text speed and brightness. There is a small visual glitch on the lower left of this options menu in the form of a blinking vertical line.

This one seems easy to replicate, but please let me know if I can provide more information.

Thanks for all your great work!

Cannot reproduce this at all. Tried with original BIOS, Homebrew BIOS, EU and US Version and all 3 save places. Nothing blinking here.

SHA1 of US-ROM for you to verify: A272055ABBBF6C26B0CD54C87395D01699589161

How exceedingly strange. Occurs reliably for me in the US Rom (same SHA1) on screen, but it doesn't appear in screenshots.

Photo and screenshots attached.

It appears that it also occurs using the homebrew bios, but does not occur on a fresh game save. Save attached. Legend of Zelda, The - A Link to the Past & Four Swords (USA, Australia).sav.zip

Reproduce also on my side. Good catch ! It is not present on the real hardware.

I reproduced the glitch as well.

Can reproduce it with the savegame from RichEsq, will try to see what this is

I tested previous RBF. This issue is introduce at this version GBA_20200409.rbf. Previous versions don't have this glitch.

Thanks for researching @wwark!

I found the problem. It's due to a change in a commit from 08.04.2020 not covering all possible paths from a change in 12.12.2019. Sometimes things haunt you for years :)

It's a small edge case, but could hit any game.

Lastest commit should fix it. At least it does for me. Testbuild attached.

Thanks to everyone for finding, reporting and testing!
