Here's my findings so far, make it it what you will.
When unpacked, there are smc.m and sfc.m files with a seperate file for each language but when compared to the fan translated rom it's quite smaller, 4MB for the original and 2.7MB for the new file and isn't playable when attempting to run it on snes9x, the program crashes.
My assumption is the rom is compressed as simply renaming the file doesn't work properly, I am curious whether this is a new translation or is it just using the preexisting rom.
Having said that, som has a gameplay improvement and retranslation hack that make it better than the original and as far as I'm aware the original translation for tom was buggy because of size limitations that the fan translation doesn't have as far as I'm aware.
