Save-feature on the Easy Flash
According to what I have (superficially) have read, the EasyFlash allows you to save data on the fly to the cartridge. I don't know of any other HW which allows this.
I was wondering if this could have been used as a "save game" functionality or is this a bad idea?
Reason I ask is due to a crack project I'm working on (for ages) which is made for the "C64 Game System Cartridge" and I was wondering if I could get rid of the need for any disk IO by porting it to EasyFlash. |

Indeed, 64kb to erase as minimum. When working somewhat incremental you can always add to those 64kb as a large save bank and only need to erase and re-save whenever the 64kb block is full.
Given that one is using a complete 64kb bank as save bank that is. |

Yeah, that is sort of the weak spot.
Also they need to be in one chip (obviously), so not spread across high and low. |

Thanks for your explanations, incremental writes seem a good idea, I gonna implement that! :) |

FWIW, Prince of Persia uses a single 8KB bank for saving (each save data is 3 bytes, iirc), so it just adds the saves incrementally until the bank is full, it doesn't erase data at all. |

Ultima IV Remastered uses a pair of 64 kB banks that it alternates between:

Wow, was 3 bytes enough to hold player location, life, weapon, which enemy is dead etc? Or do you just save general progress (max health, level etc) and reset level state completely on load? |

DOes someone has the latest binary files for the EAPI? I found the source but figured if someone has the binary I'd save the trouble to convert it / assemble it with an assembler I don't have installed. |

add something more on that entry. as it is doesn't make any sense.
EDIT: Ok, no response was given, entry deleted. It's probably part of a commercial product so doesn't belong here.
Don't use CSDb as a download site for passing non-scene files to others. |
