|
|
Hello,
I just received my MD-PRO Flash Cart and it works great for commercial roms but I can't seem to get rom hacks to work on it.
The rom I'm trying to play is Knuckles in Sonic the hedgehog.
You can download it here: http://www.hacking-cult.org/?hacks/25/x
When I put it on the cartridge and turn on my genesis I get a red screen and nothing else... I checked the checksum and it is correct.
Does anyone know how to make hacks work with the MD-PRO Flash Cart ?
Thanks for the help. |

Many times hacks, translations and homebrew games are not tested on real hardware, only on inaccurate emulators. |

This one is developped by stealth though, a well know hacker that always checks his hacks on real hardware. So I just don't get why it doesn't work... |

Ok, I found a solution to this problem.
Posting it ere for people who have the same issues: some hacks REQUIRE the cartridge to be completely full to run.
Hope this helps ! |

Red screen means the rom has an incorrect checksum. You can use uCon64 to calculate this and set it. |

The thing is some hacks are so done in a way that they check the checksum of the cartridge you write them on that's why this one hack I was talking about requires the cart to be full of other games, if you check the checksum then still get a red screen try to fill the cartridge. |

Make it so it's full in capacity: 64MB/64MB not 59/64.
Here's a game list example:
-rom hack (the hack you want to play)
-sonic
-thunder force
-game 4
-game 5
etc
Untill the cartridge is full. |
