Wanted! Coder for MapEddi2 hack
Hi there. I am searching for a coder who would like to hack a rather unique C64 tool.
MapEddi2 originally had been developed by Mario Knezovic/Bonespark and was supposed to create character based backgrounds for the never released game Lethal Xcess.
The editor supports basic features like variable maps (about 20 screens max), multicolour charsets and 2x2 blocks. Most interesting feature is a something I would call mini-fli. It is possible to switch up to two usually fixed colours or one colour plus the whole character sets each block line.
The graphic artist is able to use three character/block sets for each background map. There are no restrictions related to the resolution.
But there is a problem with the controls, because it requires a special adaptor and an Amiga- or Atari ST mouse. There is only one existing adaptor left and unfortunately it is broken.
IMHO it is a tragedy that this phenomenal tool is useless this way. I would be very pleased if somebody could create a hack with a 1581 mouse support. The result is dedicated to the scene non profit.

Hi Ninja,
Thanks for this version, it really looks promising. Here my first impressions by using Vice. I will check this on my C128 later.
The mouse-buttons are switched and for some reason the program crashes if I tried to load a file.
You will get a pointer in the disk menu if you read the directory first. It is some kind of initialising process, because the original adapter is connected through the serial port and affects the diskdrive sometimes (probably not the most elegant way to do that)... |

The crash is probably because the mouse driver gets overwritten by the loaded file. I assumed the current place for that code is not safe yet, but I could not load a file for testing :) Will fix this and the switched mouse buttons this evening.
The original adapter was connected to the serial? From the code, I'd say it was connected to Port2. Or was there more to that adaptor than just mouse?

Port 2 is right. The serial port was used for the right mousebutton (don't ask, I do not know the reason why)...
just found a photo of the adapter.

mmh, why not simply use some keystrokes instead of designing a special hardware just to get the right mouse button working? (i mean that was back in 1991 then!)
Besides that: The game looks just great! (very good conversion comparing to the amiga-screenshots)
i wonder the "minifli"-routine and the spritemultiplexer worked without flickering |

well, I'd use a timer-nmi interrupt to hit the badlines, and raster irqs for multiplexing. thus, "mini fli" changes would have a priority over multiplexing, which can survive a delay of a rasterline or two if it's coded with the nmi's in mind, and there are not too much sprites around. |

gpz: well, the second button was routed to POTX and there seemed to be a problem, that it could get stuck. Maybe this additional line from the serial port was kind of a reset for that button? Who knows, maybe the hardware will show up again, then we can have a look.
By the way, Veto and I consider the case of converting the editor to 1351 closed by now :D |

Mario told me recently that this is exactly the way he did... |

Not all mice are equal. I have a Roctec Amiga mouse which works just fine with Amiga but buttons refuse to work with C64. Not a big loss, it's crap anyway :) |
