I've decided to go ahead with the ems carts, or the PROM carts if they can be made.  I contacted kitsch and am waiting for any answers to whether or not PROMs have the room to hold mGB

the official (widows only) client software sorta sucks and some people have had issues with them getting stuck on a page. The cartridge shell is not that great.  Older ones killed batteries on game boy pockets, which should not be an issue if buying new.

What are the downsides to the EMS carts?

I am a bit confused, but neither should be difficult.  What re you trying to do?

I may be wrong, but I think he has sold both programs with PROM carts.  both are mentioned in the comments on the page i linked.  Then you just need to pick up a link cable and an adaptor (also used for getting additional software on nanoloop carts) if using mgb.  you can get a nanoloop adaptor here: http://www.nonelectronics.com/catalog/i … cts_id=172

If you are a fan of muddy gb give music tech a shot: http://gbdev.gg8.se/files/musictools/PixelH8/
I prefer muddy for some things, but I have trouble hitting diagonals cleanly.

That answers another question I had about arduinoboy compatibility and such. I'll probably get some nanoloop carts once they're back in stock.

Another question, how exactly do you load mGB on the nanoloop one cartridges?

Mgb runs great off both nanoloop one carts and 64mb ems carts, so go with whichever suits you best... both work using the nanoloop usb adapter or an arduinoboy, so you've got options there too

I originally was going to get the PROM carts, but I confused muddyGB and mGB...

The other thing being that the rom is to large to put on a PROM, so

Anyhow, thanks for the help, it's a start to a pretty big project.

For cheap, readily available flash carts EMS is your best bet.  I suggest it so that you have more options on what you use it for, especially if money is currently tight.  Another option is a PROM cart with mGB from kitsch-bent, although they seem to be sold out ATM.  http://store.kitsch-bent.com/product/ga … -cartridge

I'd most likely get a ems usb cart as it would be the easiest to get a hold of, but I'm definitely open to suggestions as to other flash carts.  I don't have a lot of money currently, so I'm mainly looking for something cheaper than the ems carts.
Thanks for the help though!

I don't recall having any major issues with nanoloop and underclocking, but I will leave that to others to fully confirm.

Benefits of an EMS cart is you can play games if you change your mind, and it keeps your slot clean and closed off and other things related to being an actual cartridge and having that case.  Benefits of nanoloop one is nanoloop and less it is less flakey in my experience.  Also supporting oliver working on moar nanoloops.  What flash carts were you considering?

There might be another option...maybe a dedicated non-flash cart.

I'm deciding whether or not to get a flash cart or nanoloop cart. The carts will only be used for running mGB.

I'll be changing the clock speed on the gameboys as well (I'm not sure if I heard something about clock changes not working well with nanoloop)
