Black screen

[scalp42]

Hi @ShadowOne333,

Thanks a lot for putting all this together. Unfortunately, I keep running into a black screen, using RetroArch with Snes9x 1.61 (tried on a Miyoo Mini as well).

I'm using https://www.romhacking.net/patch/ to patch (but I've tried other tools as well) and no dice.

I can confirm the MD5 is correct: 608c22b8ff930c62dc2de54bcd6eba72 and I've only applied Link to the Past Redux.ips per instructions (no optional patches added yet).

Final MD5 when ROM is patched with just Link to the Past Redux.ips is 69ac9b4587fba461c3f776d29b4a46c3 if by any chance you could confirm.

MD5 for Link to the Past Redux.ips is 8912ce507e71b96654cb73a517907fc1 (using the latest release from GitHub, v10.1).

I'm out of ideas, any help would be greatly appreciated 🙏

Most likely you enabled the "Add temporary header" option on the online patcher. I tried patching a clean ROM with the online patcher, and the patched ROM works fine on my end.

The final MD5 checksum for the patched ROM with only Redux patched is: 5e6da17ada2a9d85cef3263fcd2de658

This is the data from the online patcher:

Make sure you have the exact same data from the clean ROM and that you only use "Link to the Past Redux.ips".

The plot thickens, screenshot to confirm no temp header added:

MD5 (Legend of Zelda, The - A Link to the Past (USA).sfc) = 608c22b8ff930c62dc2de54bcd6eba72
MD5 (github.sfc) = 69ac9b4587fba461c3f776d29b4a46c3
MD5 (romhacking.sfc) = 5e6da17ada2a9d85cef3263fcd2de658

When using package from https://www.romhacking.net/reviews/8127, it works and I get the same MD5 as you.

When using the latest GitHub release, I get a black screen and a different MD5 hash 😅

[ShadowOne333]

That's expected. The GitHub patch is made with the source code in this repository, while the Romhacking.net patch was made still using the old method/tools of binary hacking.

I patched a clean ROM with the GitHub patch just now, get the same MD5 sum you posted and it runs fine on Snes9x for me, so both the Romhacking and GitHub patches work on my end when patched in a clean ROM.

Thanks for the quick feedback, appreciate the help.

I've tried many times to be sure with the latest GitHub release. I always end up with the MD5 for the patched ROM 69ac9b4587fba461c3f776d29b4a46c3 and I just can't get it to work across different combinations of platform/cores so I have no idea 😭

EDIT: ~I might have found the issue 😩, I'll report back~ the saves states were messed up 😮‍💨

[ShadowOne333]

I recommend deleting the save file too, not sure if that causes issues. I'm running Snes9x 1.61.

I didn't see your answer in time but you're right, I think it was trying to load a state not compatible. Nuked everything and I was greeted by the title sound!

Thank you again for the help @ShadowOne333, much appreciated ❤️

Closing the issue but hopefully it helps someone running into the same issue 🙈

Thank you again!!

[ShadowOne333]

Awesome! Glad to know the issue got resolved. Enjoy the hack!
