ROM file sizes

"Export to ROM" now only expands if necessary.. changing fixed-size things won't bump your ROM up to 4 MB anymore.  If you added things, it first pads it up to 3 MB if necessary, then to 4.  If it goes over 4 (which won't play) it will warn you on the little status log thing.

First off, it's great to see that you're still working on this. I was getting worried about you there for a while.

Second, there are some fresh out of the oven updates to Zsnes and Snes9x that allow roms over 4mb. http://www.romhacking.net/utilities/904/

Ah ha - well that's for ExHiRom/ExLoRom addressing; SOM is HiRom, which is bound to 4 MB, but a conversion has crossed my mind on more than one occasion. Depending on how ExHiRom works (I haven't been able to find much in the way of documentation yet, but from what I understand it's largely a combination of HiRom and LoRom addressing) it may be simple to do this conversion.
