I don't have an Edge myself but since it is a Cyclo clone and the Cyclo firmware has already been updated to work with DIY, if you have the latest firmware you should not need to patch the ROM at all. Just run a clean ROM and it should work fine.
Nope, EDGE isn't updated... In their site, their latest firmware is 1.9... Here are the changes: # Fixed save size for 4323, 4568
# Game compatibility fixes (DSi 0040, 4356, 4747, 4748)
The D.I.Y's number is: 4769
