Please note this is not compatible with the Acorn Electron as it uses Mode 7, it can however be also used on a BBC Master

Development

• Editor          - Visual Studio Code gives ability to use version control and better copying and pasting than using an actual BBC computer

• SSD Generator   - BeemASM, this is used to copy the basic files onto an SSD image

Teletext Editor - https://zxnet.co.uk/teletext/ This was usd to prototype the fruit symbols, once designed the codes were manually entered into the editor as data statements

No Assembler was used in making this game, it is 100% basic

NB SSD (Single Sided Disk) are used within the BBC Micro Emulators

Following 4 files are stored on the SSD

• !BOOT  : This file loads the game by allowing the user to Shift Break on the machine.

• LOADER : This files stores the envelopes for the sounf effects and the game instructions

• SLOT   : This is the main game file, which has been crunched to make the game work faster as it's been written in BASIC

• SOURCE : This is the main game file before it has been crunched, so that it is more easily readable (This file is not used in playing the game)        

How to play

There are quite a few BBC Micro Emulators available, probably the simplest one to use is

jsbeeb which is an online emulator tht van be run in a browser making it available for most operating systems.

This is the link to jsbeeb https://bbc.xania.org 

Load the SSD from the Disk menu abd choose from example or local and navigate to the SSD file

One loaded press Shift Break for the game

Other emulators can be used such as BeebEm, but they will need to installed to your computer first before you can load the SSD file.
