Save Game not transferring

[Questinghero]

This may be a side effect of the SA-1, but My save that I have been slowly working through for years, wont load on this new wide screen version. the srm will load on both snes9x and bsnes (and bsnes-hd) on my current MSU-1 rom, but when I rename it to load on the widescreen version (in bsnes-HD), the game looks as though it has never been played and wants to start a new game (overwriting the other srm file). Does this new version write srm files differently than the original game did?

The save game from the original Super Mario World is not compatible with the widescreen version. Even if we modify the save game manually to the SA-1 area (which works if you are using SA-1 Pack only), there is a few changes in the overworld that would make the save game simply don't load properly and you would end up stuck in a certain regions of the map, since the save file caches a bit of the player path information. Widescreen SMW changes most of the overworld path to work better with the extended widescreen region.
