Cross rle or equal char packer
I'm looking for a Windows commandline rle or equal char packer with at least these specs:
Memory range from $0200 to $ffff
Should create a runnable executeable with sysline
Anyone know one? I searched the net, but didn't find anything except pack64.exe included with Tass, but it didn't work here.

I guess RLE packer are so basic, everyone who ever needed one, coded one. I doubt you will find ready-to-use generic RLE packer. Sounds like a job for a human code machine if you ask me ;-) |

Is it of really that much importance it's RLE? Wouldn't LZ be ok aswell because then you have pucrunch and exomizer to choose from. And perhaps with cmdline options you might be able to turn of the backreferences in pu or exo to get only the RLE part? Perhaps... |

@enthusi That's what I hoped for: someone willing to share his small crosscruncher ;) I'm lazy, you know...
@JackAsser Not it's not so important it's RLE, but it should decrunch as fast as possible and the starting adress should be $0200 or lower if possible.
I need this for the generated output of my Modconverter. I know that I can move some stuff around internally and crunch with Exomizer or Pucrunch afterwards, but the decrunchtime while testing the module in WinVice isn't optimal for the workflow. |

Oh ok, but if it's just a workflow issue I suggest you simply save the whole shit as a big uncompressed .prg file and use the new DMA-load in VICE to push the data into memory. |

I didn't find anything regarding a DMA-load feature using a commandline switch. Is it possible to load the whole memory and give a startadress? |

Wouldn't you need to delta encode before RLE to gain any significant reduction in final data size?

@Groepaz&MagerValp: Wasn't this some new feature in VICE 2.2? Have I been dreaming? :) |

Couldn't you just use -moncommand to issue a series of commands to change $01, load and jump to start address?
Or be quick with enabling/disabling warp mode... :) |

ec64 (the c64 emulator) can do both.
Launch PRG via RAM-injection and enable/disable frame-limiter for a certain amount of frames via script.
There is a good chance though that it wont run your MOD-player =) |

@Devia I don't think that delta encoding makes such a big difference with a rle packer. Even Pucrunch is only a few percent better with delta enconding enabled.
@Mr. Sid I think your idea is too complicated. Would be cool, if Vice had an autorecognition for packed files and would enable warp during decompression. Could use the same technique as Ian Coog's unpacker.
@JackAsser I thought you knew how this DMA-load thing works?
@enthusi WinVice is quite good at emulating $D418, DigiMax and waveform digis using resid-fp. I don't think ec64 handles this very well. |
