I was thinking of just buying a cheap and nasty EPROM burner (http://tinyurl.com/nzssgo)

I also need some 27c801 and 27C040 EPROM chips, anyone got a place where they stock these and post to Australia?

I found a seller on Ebay whom sell them (http://tinyurl.com/nwyqe9) they have the correct serial number, do I need to worry about anything else apart from that?

I also need some 74ls139 chips which I assume (according to snesdev.romhack) are needed to join 2 or more chips together.

Does anyone have any other helpful pointers before I start buying all this junk?
For the EPROM, try JAMECO. JAMECO Website I think that versions of the 27C chip have higher memory density with the same pinouts, so you don't need a memory mapper to make larger games. I think they make them with memory densities up to 8 Megabytes (64 Megabits).

With used EPROMS, you do need to worry about getting ones that are not in good condition. If they've been through LOTS of write/erase cycles, then they might not be able to be written to again.

Also, DO NOT BUILD YOUR OWN QUICK AND DIRTY ERASER! The wavelength of UV light used is the same as a microbicidal lamp used to sterilize hospital equipment. As you might imagine, that is not the best thing for a human being either. Go ahead and invest in a small eraser unit because you will probably mess up a few burns, and there is no reason to just toss those chips out.

Also, you'll probably want a list of cartridges with pertinent data, so that you can select an appropriate donor cart. There is a list out there [that I can't find at the moment] that details just about EVERY SNES game released, giving the ROM size, save memory size, type of cartridge [lorom, hirom, SuperFX...] and such like that.
