Real hardware issues

[Max833]

Every single game ever officially sold has been tested with bsnes (with firmware roms), and zero bugs are currently known. But there were some "hardware issues". These looked like bugs but were confirmed to occur on a real SNES.

We should keep track with real hardware issues.

I used the European cart, but that doesn't probably matter. Screenshot: https://user-images.githubusercontent.com/53529402/131505438-4e806090-6ef9-42bf-8f2d-f2d8e809c524.jpg	ZSNES forum

More infos about Blargg's issues:

Listed are music tracks that have been tested on hardware and verified to sound wrong or odd, either due to a bad rip or because they just sound that way. Refer to this if you're developing an emulator and find a music track that sounds wrong, before you look for a problem in your emulator. SPC tracks have been verified by loading them into the SPC-700 unit on a SNES using a custom development cartridge.

Can we pin this, @Screwtapello, @Kawa-oneechan? I didn't know something like this is possible until I saw it here:

[Max833]

Thank you! =) It took a while, but I have now searched the ZSNES forum as well and written everything in this thread.

[Max833]

Aaand the last update for a while now. Looking good. 92 entries! ^^

I can see it animating just fine on the 2021-09-06 nightly.

There are two versions. Just Rev 1 has this problem.

Secret of Evermore - Broken dialog bug

How to reproduce:

• Use the sav file contained at (SOE.zip), on the US version of the game, enter slot 3. (with bsnes: convert save file to .srm -> https://calc84maniac.github.io/tiboyce/saveconverter/

• Get into the dry river by going right, go down through it to the next screen.

• Follow the left path, go through the dry river until you see a cave. Get in

• Use the teleport

• This is a puzzle, Use the spell levitate on the big rock to put it in one square, then put your character in the other square, press select to move the dog, put the dog in the third square.

• Go up through the pass that just opened, use the teleport.

• After the dialog with Tiny, you need to get into the room in the middle. For that, use the teleport that you just used. And then the same one again and again until you end up there.

It's a bug on real hardware, so accurate emulators should show this.

bsnes has the same issue. So... that's good. ^_^

Entry # 97

Secret of Evermore - Unable to finish the game forever

Taking advantage of this issue tracking, this is the bug that will prevent you to complete the game forever and that I was able to find out and trigger.

I think this happens when you get the Gauge twice (known bug that makes second gauge work as Diamond Eyes), then the Wheel then finally the Diamond Eyes by defeating Tiny.

Just open third save and check the bag of charms that there are the Gauge, Wheel and Diamond Eyes. After leaving the Inn, go far east and get the flying machine and go see Tinker. Talk to him twice then check the bag of charms. You got only a Gauge and no Wheel nor Diamond Eyes.

Since there's no way to get another Wheel in Bugmuck, you are unable to finish the game forever!

@Max833 Would you be so kind as to upload the markdown as an attachment so we an have an offline copy of the hardware issues? We could also commit it to our fork to help ensure this list is never lost.
