The genny cart doesn't really use any mappers. But the genny supports several different size carts, like 8megabit, 16megabit and 32megabit. The large carts are mapped to more pins then the smaller carts are. So there is a chance with the sports games that if they are smaller carts that if you try to put a 32 meg chip in there you it won't be wired to all the pins.
Of course you can modify the cart to do this... but you'll need to know the engineering of it. Which requires some knowledge that if you had you wouldn't be asking this question.
The guy at that website probably makes those carts from scratch. There isn't a whole lot to the cartridge itself... it just takes the EPROMs and maps them to the correct pins for calling on it (except some of the special carts like Virtua Racing). Your best choice would be to get just a flash cart that can be reflashed... EPROMs are expensive and can be a bitch to burn. Any screw up and you have a junk EPROM (they are not re-writable).

He probably does use a lot of spare parts. Things like the casing and everything. He doesn't sell those games cheap you know... and yeah, he might use the boards out of old carts, but he probably parses through them to match the smaller carts up with the smaller roms. Most Beta's aren't very big, so putting it on an old sports game cart might work out.marurun wrote:But EPROMs just aren't expensive enough. They really are cheap in smaller quantities. The major expense is the writer tool. I just don't see how one guy with probably small numbers of orders would see any return having custom carts manufactured or using flash carts. It doesn't make financial sense.
But in the case of burning say Sonic 3, well... you need to either make a cart, take a 32meg cart, or take a smaller cart and hope the pins are all wired up. In a lot of cases they are wired up, in others they may not be.
Go pick up some of those 50cent titles, tear em' apart and compare them to known 32meg carts. That'd give you the best answer you are looking for.
I never said it was impossible, I just said it takes a little know how. And at 50 cents to a dollar per megabyte for EPROMs, well that sounds pricey to me.
