Sappy made my game unreadable

[papascoops]

I had finished entering all the music I wanted into sappy then it crashed both of Oaks and all of the Route tracks. Then when I fixed the crashed ones it broke my rom and now it won't read on any app, is this fixable or do I have to start over?

I also wanted to mention that the rom itself was working fine before I started sappy up, it is now just not reading on anything like VBA, Advanced Map Editor, etc. it says it's not a proper rom or it isn't recognized on all sorts of apps

Can you show us the exact error message that comes up when trying to load the rom now? Also, in future, try to make it practice to always create backups so you never risk starting from scratch

No error message on VBA it's just a white screen, I have a backup but it was before I inserted one new map on AME and 4 songs on Sappy. I am at work rn but when I get home I can upload what they say.

You likely overwrote data in different offsets that are critical into booting ROMs. You have to start over.

Sappy isn't really stable, so you have to be careful using it, and always make backups
