Action Replay question.
G'day homoerectuses!
A mate just gave me 2 Action Replay cartridges, a 4.1 and a Pro 4.2, I've gotta choose one and give the other one back, anyway here's the question,
looking inside both of them, the PCB's are identical, but the Pro 4.2 has a second 28 pin IC soldered in. That same socket inside the 4.1 has nothing in it. Looking up the IC specs on the net, it comes up as 64kb SRAM. I'm guessing that's the difference between the Pro and standard AR's? |

i would keep the one with the ram. some programs are able to use it, and also some of the action replay routines work better with it, especially the freezer. |

Sorry, which programs are actually capable of using the AR extra RAM? Doesn't the AR6 also have extra RAM (32 KB IIRC)? |

action replay has 8 kb ram, only the retro replay comes with 32 kb. |

no, you mix up kbit with kbyte. 64 kbit = 8 kbyte. |

Cheers guys, I'm thinkin about burning the Cyberpunx Replay rom and smacking that into the cart, has anyone done it, is it worth doing, or should i just stick with the original? |

that will not work. cyberpunx replay is made for retro replay hardware which has more features than the old action replay hardware. also, the cyberpunx rom uses the reu compability mode of the retro replay which means that a different memory layout in i/o space is used which is incompatible to the old action replay hardware. |

you can not burn the 64KB roms, but there are also 32KB cyberpunx roms available..
BUT i wouldn't burn those roms to your AR. They're too unstable and lack too many options imo.
most annoying is that a certain byte (around $8000-$9000) gets destroyed after resetting, leaving you wondering why your code doesn't work anymore..
this hast cost me quite some time when the RR was released first. i cannot live with this error myself, so I have my own version of the AR6 rom flashed to my rr..
don't burn the 32K rom to your AR, just stick with the original AR rom, or to one of the special released roms with different function-key settings (i wouldn't use them, but maybe fcIII function-keys are good for you) |
