4 Pak All Action, on real hardware
Posted: Tue Sep 24, 2019 9:01 pm

I wanted to know if there was a way to make the 4 Pak work on a real SMS. all I get is the menu and then when I pick a game it goes back to the selection screen. I was thinking maybe a way to make 4 hacks to have them boot up the individual games. I've tried getting it to boot with my everdrive on a real SMS and on a Mega SG jailbroken with it loading the Korean BIOS, nothing seems to work. | |

I thought the individual games were available as separate ROMs already?
Edit: apparently not, it's a custom mapper but seems possible to hack to the Codemasters mapper supported by Everdrive. |

Is this something a beginner in hacking could do... the most ive ever done is add IPS to a rom. I have a basic understanding on how read the hex in the header. |

It's actually pretty basic but a long way from what you're used to... I may have a go and write something up about it. Technical details are here: http://www.smspower.org/forums/post69724#69724 | |

Yeah, I understand some of it, but not enough to fix the mappers. Reading the post it looks like some made a hacked version at one time, but I didn't find it yet. | |

Here it is, as promised. These are lightly tested. Guide is inside, along with source. Most were written in a way that makes them very easy to patch, or to combine into multicarts some other way. I went a bit further by adding Sega and SDSC headers where possible, and mapper initialisation code, to maximise compatibility and traceability; but the initial hex editor patches (one byte per game) were enough to make it work.

Wow, thanks. I'll try this on my Master Everdrive. | |

They all work on my X7 Everdrive. The only one that I thought was terrible was Adventure Kid. But it's nice to have them to try out!
Thanks again. |

Thank you so much for these patches! I've been curious about the games on this unlicensed cart for a while and can confirm that all bar Adventure Kid run great on my Mega Drive via an EDX5 (as expected). Very cool. |
