| Post subject: | Using RAM in RetroReplay/IDE64 for general purposes |
I was wondering how much RAM it is feasible to "steal" from Retro Replay (with fastload/fastsave in use, but nothing else), or from IDE64 (is 100% of the memory normally used for buffers?) |

Good question. I'm not aware if the fastloader in the Cyberpunx ROM or the Final Replay ROM actually use the RR-RAM. That should be fairly easy to find out though by comparing the memory before/after a fast load event. |

RR - depends on which ROM is used IDE64 - "External RAM is not intended for users! Please DO NOT change any information in External RAM!" |

The Retro Replay is fitted with 32 kb of RAM, while the original Action Replay 6 only had 8 kb, which is used by the fast loader. Thus, we have at least 24 kb of untouched memory! As far as I know, the Cyberpunx ROM only makes use of the whole RR RAM for the new splash screen function. |

Here is the RAM usage for Graham's TFR ROM:
$2000-$7FFF Which is most of it. As to the actual upper boundary of the used RAM, Mr. Selck said it varies. The safest bet is to not go in the $9xxx addresses in the lowest RAM window. The 3 others are completely free! |
