 Posted: Thu Jun 04, 2009 2:53 pm Post subject: Flashing program for DOS? |
 |
|
Any option for me to flash games onto my MD-Pro 64M under DOS? I have a PD ROM here, which I want to flash, but the only computer I have here with LPT at the moment is my Pentium MMX 166MHZ box which is running DOS 6.22
Any chances? |

Very nice. Works flawlessly.
I'm coding a DOS frontend for it for use with MD-Pro  |

| Cool. Be sure to submit it to the ucon64 folks. The guy working on it is fairly responsive to fixes and such. I submitted two patches related to MD-Pro support a little while back. |

Nice! Got that "authentic" DOS look to it. 
I guess the next step is to add the ability to load and save the saveram. Remember that the MD-Pro gives you 4 banks of 32KB of saveram. |

Thanks for your reply! I am working on that. I am studying the switches of ucon64. Kinda complex stuff going on there  |

| Yeah, multi-game is especially fun. That's why I use the uf frontend. That way I don't have to worry about the switches. |

Here's an example command line for two games (in linux):
| Code: | | /usr/local/bin/ucon64 --multi=32 /home/jlfenton/Tools/ucon64/MDPACKU4.BIN /home/jlfenton/Tools/ucon64/roms/rom1.bin /home/jlfenton/Tools/ucon64/roms/rom2.bin output.bin --region=1 --frontend --port=378 -o=/home/jlfenton/Tools/ucon64/roms |
That doesn't burn multiple roms, it makes a bin file with the loader and multiple roms. Then you burn that image just like normal. With the MD-Pro 64, you also have --multi=64. The region option allows to do things like force everything to NTSC/USA (which is the value in the line above).
The files are always the loader first, followed by the rom images. |

Very nice tutorial!
I completely understand now. This isn't hard to add, I think I'll have it done by next week as I'm on a retro computer and gaming party on the weekend and got stuff to do till then.
Many thanks |

No prob... I just cut n pasted the line uf outputs to ucon64. 
If you need other examples, like for the sram banks, let me know. |

| Yeah. The SRAM I REALLY don't understand. It seems to me that it fetches or puts the SRAM according to whether there is something there or not. Seems not controllable to tell it to write or read sram separately. |

Receiving sram:
| Code: | Executing: /usr/local/bin/ucon64 --xmdb=1 /home/jlfenton/Tools/ucon64/game.sram --frontend --port=378 -o=/home/jlfenton/Tools/ucon64/roms
|
Sending sram:
| Code: | Executing: /usr/local/bin/ucon64 --xmdb=1 --frontend --port=378 -o=/home/jlfenton/Tools/ucon64/roms /home/jlfenton/Tools/ucon64/game.sram
|
The --xmdb=1 sets the bank (1-4 if I remember right). You also include a file in the parameters. If it exists, you're writing the file to the sram; if it doesn't, you're writing the sram to the file. It is an odd way to do it, but that's what they do. The -o switch doesn't seem to do anything here... it probably isn't needed, but the frontend sends it anyway. |

| Yeah, that's how I understood it. Yesterday I redesigned the GUI for the SRAM to fit in. Now that you showed me how it works, I kinda have to redesign the SRAM part |
