Both those mention as being for
Super Mario World (USA).sfc - NOINTRO

Check the hash against your ROM and if they match those then it should work. Issues then tending to be whatever emulator or flash cart you are trying, which on the SNES can make things tricky (older hacks, though these look newer, might well use emulation shortcomings of older emulators to give themselves the abilities to do things that hardware can/will not). The SNES does not have as much issue with headers as some systems but it is still a thing, to that end your "bad" ROM might merely have or lack a header as needed by the hack
https://www.romhacking.net/utilities/608/ should be able to remove it, though many will find it just as easy to get another version.
There are online hash generators, plenty of offline ones too. Indeed the zip/rar/7z the ROM likely came as will have noted the CRC32 at least. CRC32 is pretty weak as these things go (later in the GBA lifetime we saw ROMs with intros adjusted to match the CRC32 of the stock ROM) but as far as figuring out if you have the matching version from the basics mentioned below it should be just fine.
More generally issues tend to be from wrong region, wrong version (sometimes bugfixed versions get released and called v1.1 or something, some games making it high up the list of numbers --
https://www.zeldadungeon.net/wiki/Ocarina_of_Time_Versions ) or some extra that a dumping tool or management tool added to the ROM or the patch expects. Readmes tending to note what it expects. The other issues tending to come from people trying to stack hacks which is its own kettle of fish (it can work, even for hacks not necessarily designed to work together, but it also might not, and the tools that detect collisions/same sections being overwritten are far from the whole story even if a good first pass).
