What are the restrictions on when you create a cart game? I did see that Pier Solar is 64 MB, and i know that is alot for a sega megadrive game. But what are the limitations for this? I Pressume that it wont be possible to have an 256mb game because the cartridge chips are expensive? or non excistint?

Which is plenty for most games ( especially when you don't have a team of artists & heaps of time ). For example, Phantasy Star IV is only 3MB / 24Mbit. But in theory you can make it as big as you want. You can include a low-power 32GB flashdrive on your cartridge if you want ( and you've got the engineering skills .. and you're crazy ). |

Most flash carts allow you to do homebrew that can use the SSF2 mapper for up to 6MB of rom. The MegaEverdrive allows SSF2 mapped homebrew to be up to 16 or even 32MB in size, depending on the DRAM on the MED cart (he mixes 16 and 32MB DRAMs when making the carts, depending on which is cheaper at the time he needs DRAMs). The MED also supports 8 or 10MB flat roms if you don't have the Sega CD or 32X attached.
Pier Solar uses a custom mapper that allows them to address 64Mbits (not MBytes!). It takes only 4MB of space, bank selecting the 8MB rom in that space.
