 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

First Impression: Great, that worked.  Some Points of criticism (not directed at you, I guess that's because of the source files): The playing field is narrower, so you can't see the paths on the left side, and the graphics are far below what they could be on the Pico, but the gameplay itself looks good.

It is a direct convert of the BBC version. If you want to have a play with colours or graphics then please do hopefully the game engine itself should allow for it. |

Yes, I found the BMP files where the tiles are stored. I'll take a look to see if and how I can edit them. But the game is running just fine  —I just keep dying way too early to make it through the level.  'no comment |

A big improvement would be to update the sprites which I think are all in one file. You would then need to look at the use of the map statement in the program. The transparent colour is currently 11 so you have the other 15 to play with. |

One problem, among others, is that the Apple II generated some of its colors using the NTSC error, which is why some colors are stored as vertical lines in the source files. This results in only half the horizontal resolution and is difficult to convert. Here are two examples: the Apple graphic and my adaptation: On the left is CUTROOM.BMP from the Apple II; on the right is my version. Below that is the sprite sheet “sheet4.bmp,” and next to it is my initial attempt to improve the sprites for RGB 121. I keep the sprites in the same position and at the same size so that no adjustments to the program code are necessary; the only thing that’s omitted is the “MAP” command. The corresponding lines can then be REMed out.  I'm using the Sega Genesis version as a guide, but I'm not just copying the images as they are. I still have quite a bit of work ahead of me, but I'm already looking forward to the result Cheers Martin 'no comment |

So, here's a quick update: I've now customized about 90% of the Prince animation sprites and some parts of the environment; next up are the enemies. The program has been modified so that it no longer executes the MAP commands. PoPico  cheers Martin Edited 2026-10-03 19:34 by Martin H. 'no comment |

I think you need a few changes to make the game very slightly different and give Ubisoft's lawyers a giggle. Prince of Preston - The search for the Holy Beard Trimmer Although I don't remember Preston being quite so rocky and I believe they have installed electric lighting now. :) (Lovely work, Martin!) .

In my thread title I called it Prince of Pico but somehow that went missing. I think perhaps I put a quote in the line. The same happened to the thread title of V7.00.00 which should have had "Scotty: I need more power" after the colon. Martin: looks great! Edited 2026-10-03 20:06 by matherp |
