Help Testing SE/30 ROM?

Can someone help verify that this ROM works in an SE/30? If I made the changes correctly, it should have the checksum test removed and also skip the RAM test while booting. I figured I could just test it in an emulator before buying a ROM SIMM that had this on it, but no emulators seem to exist for the SE/30, IIx, or IIcx. I really want to avoid having to buy the ROM programmer if I can avoid it.

I've now received my ROM SIMM with this image on it, and can confirm for myself that it works as expected.

Bolle, when you are burning these smaller ROMs (I believe Sunoo's IIcx ROM was only 256 KB), are you erasing/writing to the entire SIMM? Or are you appending to an existing ROM disk image? I can't get past this first step unless it's a full 4 MB/8 MB ROM.

The Software I use for flashing fills up the remaining space automatically depending on the selected chip. If I select 29F040s but only load a 64k file the rest just gets filled up with FFFFFFFF...
