Turbo Chameleon enhanced graphics modes
I'm planning to get a Turbo Chameleon when the next batch is released. I read "Special software can use more colours or higher resolutions" on a sales page. Does anyone here know what these enhanced graphics modes are and where I can get further information?
Thanks! |

yeh, I dunno. At what point does it stop being a c64?
Maybe the TC can help reduce the FLI bug, or even possibly allow some new modes (you should be able to produce some pretty neat splits to add more colour at the very least). |

Quote: Really >20MHz ? Heard TC64 is about 5-7 times speed up only.
Where/how is that speedup measured (if at all) ?
On the TC FAQ you can read: "Between 10 to 14 times faster for tight loops that only access memory (e.g. decrunchers) and between 4 and 6 times for I/O heavy apps. Basic programs run about 12 times faster on average. Look at some Benchmarks !" And the link to the benchmarks: http://wiki.icomp.de/wiki/C64_Benchmarks |

And remember that those benchmarks are tweaked in order to make the Chameleon look good.
After I told Jens that the SuperCPU ratings would be much higher if one enabled the proper optimization mode, he refused to publish the results, and instead added the "all writes must go directly to C64 memory" text on the page, which is totally not true for Chameleon which never write to C64 memory and instead tricks the VIC into fetching all its graphics from the Chameleon. |

Yeah it eliminates interlace flicker, and with the extra speed probably eliminate the FLI bug and do some clever raster tricks. |

It stops becoming a c64 when it does something that is impossible on a stock c64 :-) aka using supercpu, turbo chameleon turbo, reu, etc.. |
