    Jazz you ever do multi carts? I read simply pasting the code of a game on the end of another allows you to have 2 games that will toggle via reset. So as using 2 1MB games to make 1 multi 2MB game. I tried it and it did not work. I copied the hex code of game 2 and pasted at the end of game 1, and saved file. I then opened the file, byte swapped it, programmed it, and it only plays game 1. Reset just resets to Game 1.

    That will not work. See my second post in this thread. The tutorial is old not finished though.

    I did not read this info from this thread. This statement was made in a youtube comment by someone.

    "FYI if you take two bin files (post byte swap) and merge them into one bin file and write it, you get a two for one game that splits based on the RESET button.. e.g.: instead of filling a 2 meg with FFFFF you can flash two 1 meg games, hit RESET and it will go to game #2, hit again, game #1."

    Hi,

    I ve read almost everything it this thread (not that I understand everything, but Im trying). I ve learned how to make common non-save games of different sizes and some battery-save games too.

    What I'm trying to do now is to write some LARGE hacked ROM on to cartridge (It is Hacked UMK3 rom, so no save). It's working on my friend's flashcart on MD1 well. The total ROM-size is 6103KB (6.1 MB), So I guessed that I should split it like Jazz said earlier(Using H). So I got two *.bin file (4MB and 2.07MB).

    The PCB that Im trying to use is from japanese SHINING FORCE I. As I see it it uses TWO Sega Roms on it. (When I first saw it I thought AHA!!) How do you think will it work if I just solder two 27C322's(4+2.07) on it? Will it work? And then what is the order in which I should solder them, which one's where?

    The pic of the PCB - https://www.dropbox.com/s/fhzqgw3x5t...85655.jpg?dl=0 , https://www.dropbox.com/s/xaxarxrmg1...85702.jpg?dl=0



    PS. Jeez... Sorry for such stupid questions...

    A heads up to all the young players. M27C4002 is not equivalent to M27C400 even though it seams like it spec wise. it's wired up completely different.
    Learn from my mistakes, people!
