Gaming How can I tell if the ROMs were pre-trimmed?

[unpaidassassin]

Yeah I'm note sure if the ROMs I have so far are trimmed or not. They're all from the same site but I'm not sure if they trim and if I can mention the site...

anyway here's the ROMs:

Unzip them, their size should be a multiple of 8 -or something really close-.

we I just saw in another topic about trimming...I extracted a few at random and they all seem to be a multiple of 8 MB

If the size of your roms is one of thoses, you'll be 100% sure they're not trimmed :
8MB or 8 388 608 bytes
16MB or 16 777 216 bytes
32MB or 33 554 432 bytes
64MB or 67 108 864 bytes
128MB or 134 217 728 bytes
