MK14 Games Compendium - Xmas 2023
In the run-up to Christmas and the New Year myself and Coolsnaz2 will be posting some new games for the MK14.
The first one is a new version of Moon Lander. This VDU version is based on the original idea presented by SiriusHardware in this post. It uses the core Moon Lander code from the SoC MK14 manual with a VDU manager bolted to it. Thanks to Siriushardware for providing his original moonscape graphic . Some notes about the game:
Code:
=====================================================================================! ! Feature ! LED Display ! VDU Display ! !------------------------------------------------------------------------------------! ! Altitude ! 3 digits. 0-999. 999=touch down ! 4 digits. 0-9999. 0000=touch down ! ! Velocity ! 2 digits. Unsigned (absolute) ! 3 digits. Signed. -ve = Ascent ! ! Thrust ! Not displayed ! 1 digit. 0-7 ! ! Fuel ! 1 digit. 0-5. F=empty ! 2 digits. 0-88. 0=EMPTY ! !------------------------------------------------------------------------------------!

Re: MK14 Games Compendium - Xmas 2023
I had a go at the beta a little while ago (Thanks Realtime) - I can 'win' the original version every time because it always starts at the same speed and altitude, whereas this version randomises the starting altitude, so I can't play my 'system' any more.
I ran it on OrtonView (with Mark1960's 74LS74 patch for the memory corruption issue in place) because I guessed it had probably been thoroughly tested on RealView - it worked well and ran for several hours without any bits going missing - not that it would have been Realtime's fault if they had, but this program is a very good stress test for OrtonView because it uses virtually all of the standard, optional and extra-extra RAM (0200-07FF). Genuinely replayable, and Realtime's game end 'verdict' graphics are a nice touch as well. |

Re: MK14 Games Compendium - Xmas 2023
Here's the next new program for the MK14 - Snake, a classic vintage game where you have to steer the snake around the screen and eat the 'apples' (asterix).
The program operates in character mode and has a very simple user interface. Key 1 to turn left Key 3 to turn right GO to start a game For each apple that the snake eats it's body length increases by one segment up to a maximum length of 126 segments. If you achieve that then you win!! I can typically get 30-40 segments before the snake eats itself. Feel free to share your top scores Snake requires continuous memory from $0200 to $07FF and base RAM at $0F00. Happy snaking!! |

Re: MK14 Games Compendium - Xmas 2023
Next new program for the MK14 – Tetris, inspired by my visit to the Retro Computer Festival 2023.
Key 2 moves object down, you get more points the higher the object is dropped. Key 4 moves object to the left Key 6 moves object to the right Key C rotates object clockwise Key D rotates object counter clockwise You get points for completing lines, Single 40, Double 100, Triple 300, and TETRIS 1200. The points awarded goes up with each level completed. I have tried to keep the game as close as possible to the original Tetris on Game Boy. Unfortunately I run out of memory on the MK14, so high scores are not kept. Tetris needs continuous memory from $0200 to $07FF, $0B00 and $0F00, with the video memory at $0200 to $03FF. The program has been developed on a Raspberry Pi with PiView and FastLoader installed, and has been tested on RealView. I hope to create a YouTube video next year showing the setup used. I would like to thank Realtime for testing and suggestions. |

- Is this only on a special virtual all-in-software emulator version ? Or is there a enhanced VDU now available (Maybe PiView / Realview?), that has added colour ? (although finding extra memory in the MK14 map for that, might be difficult). |

ortek_service The screenshot is from PiView, which has the ability to change the colour for individual characters. The PiView software is still being developed but can currently produce colour for individual games. I still have a few PiView boards available for forum members. |

I might be interested in building a PiView, once I get receive the adaptor board PCB to add RAM to finish my MK14 replica. But need to decide which version of VDU to go for (or maybe get one of each to try, as a few others seem to be). |

Re: MK14 Games Compendium - Xmas 2023
In terms of advancing the capabilities of the MK14 VDU PiView is the way forward, IMHO . Not one for the purists, perhaps, but the quality of the display is outstanding and there’s the ability to add new features (additional fonts, colour,etc) without hw modifications. You can even record the display direct to the RPi’s drive for use in videos etc.

Re: MK14 Games Compendium - Xmas 2023
Here is the final MK14 game for 2023 - a one armed bandit called Jackpot.
You have 10 credits at the start of a game. Use your luck and judgement to build the Hi-Score and gain bonus credits. The Hi-Score is maintained until the game is reset. Use the HOLD feature to stop individual wheels from spinning. Keys: 1 to HOLD left wheel 2 to HOLD middle wheel 3 to HOLD right wheel GO to spin the wheels or start a new game This photo mark-up shows how bonus credits are indicated (too little memory left for anymore text). Winning combinations and bonus credits, as follows: Code:
Same Left and Same Left and Symbol Middle Wheels Right Wheels 3 wheels the same ======================================================================= Points Bonus Points Bonus Points Bonus Pound 2 0 8 0 16 0 Horseshoe 10 0 24 0 48 1 Lucky 7 18 0 40 1 80 2 Bell 26 0 56 1 112 3 Star 34 1 72 2 144 4 Spiral 42 1 88 2 176 5 SCMP 50 1 104 3 208 6 MK14 58 1 120 3 240 7 Special thanks to Coolsnaz2 who tested the beta versions and made many suggestions to improve the look and feel of the game. Wishing you all a very happy and healthy 2024! |
