A NESMaker Multi-Games Module

Anyone ever thought of Making a NESMaker Multi-game Module?

Like you could fit 4 Normal UNROM Games 128kb in a NesMaker game of 512kb. As far as I know there is no existing Multi-cart that has just UNROM games, or more than one of them in one Cart. Also there is no NES Mapper 30 Multi-cart AFAIK.

I know NESMaker doesn't import Roms but maybe we could build the 4 games in 1 game our self's inside NESMaker some how. Anyway That is an Ideal I had for awhile. Not that I know how you could do it or if it would be possible.

Here's the problem: a mapper has to be specifically written for this sort of thing. Mapper 30 is not.

Mapper 28 is the homebrew multicart mapper (better known as the Action53 mapper) and it wraps all games into one large ROM. But it has a size limit and it doesn't accept any individual ROM larger than 256kb, nor does it accept Mapper 30 ROMs. You'd have to convert them to Mapper 2 AND a 256kb size. There's a topic on the forums on how to do the former, but to do the latter you have to plan it out from the beginning (i.e. not use half the banks in the NESMaker ROM).

You can also only fit about seven in there at 256kb; to fit more, they'd have to be even smaller. So a lot of NESMaker games just wouldn't work for Mapper 28. As for how they make those bootleg "500 in 1" carts overseas, I don't know.

You guys must be reading my mind. I was looking into this topic over the last week. What do you think about this option @Bucket Mouse ?

Well, that would fix a lot of the problems with the only other multicart compiler available (Action53). It takes Mapper 30 and it can hold a lot more ROMs. BUUUUUT.....

....it's for Famicom, not NES. Which means you can't make a physical version of it that will work on a non-Japanese system.
Why would anyone build it like this? What a waste.

Thank you, that explains why there are no Mapper 30 Multi-Carts.

Yup. The board is a Famicom board -- it has the wrong set of pins. You could include a pin adapter, but that would raise the price.

You can get adapters pretty cheap on Aliexpress.
