| Post subject: | My first game in assembler: JSnake (WIP) |
Hi all, I got in to retro gaming a couple of years back, having had a Beeb as a kid in the early-to-late Eighties. Inspired by the homebrew games on this site, and those in the back pages of Retro Gamer magazine, I've been meaning to learn 6502 assembler so I could write a simple game. Well, I've finally got started. With some encouragement from Samwise I've started a dev diary over at http://www.retrosoftware.co.uk/wiki/index.php/JSnakeDevDiary I started writing it part way in to coding.. and it's a bit big, but hopefully readable. There are some code snippets and screenshots alongside my ramblings. Sam, I can't find a way to create new pages (do I have permission or can you create me some)?? I'd like to split the dev diary up a bit as others have in their diaries. Please could you help? At this stage, I should say a BIG thankyou to SteveO for his MODE2 screen address calculation and vsync /irq routines, tricky for his Random routine (both of which can be found in http://www.retrosoftware.co.uk/wiki/index.php/SampleCodeLibrary .. I've more or less nicked them wholesale and call these routines constantly. Without these routines, I would've struggled a lot more than I have done. The sample code, dev diaries and these forums are a great resource and I'm grateful to all the contributors! When I'm feeling a bit braver and this thing is vaguely resembling an actual game, I'll put up the source code and an ssd file. Til then , I'll update the diary as and when I make reasonable progress. Comments and feedback are welcome. I'm keen to improve my assembler skills, and better my understanding of the hardware. Cheers, jbnbeeb |

Nice to see you've gone public, jbnbeeb.  I'm sure the clever ppl here will be giving you more pointers than you can shake a stick at. You should have permissions to create new pages ... there are some detailed instructions available here. Give me a shout, if you're still having problems with it. Sam. |

Yay, this is what we like to see - more victims (er, I mean volunteers) stepping up to the plate! Very best of luck and well done on maintaining such a detailed dev diary - that will prove to be a really useful source of reference to others, no doubt about it!

thanks both. I shall endeavour to keep it up. The good work on here is certainly an incentive to keep coding! |

Hi everyone, I've just updated my dev diary for JSnake. I've uploaded a work in progress video to Youtube. I still haven't solved the speed-up bug, which I have discussed in separate thread (http://www.retrosoftware.co.uk/forum/viewtopic.php?f=73&t=763).. Link to latest diary entry: http://www.retrosoftware.co.uk/wiki/index.php/JSnakeDevDiary280412 Diary index: http://www.retrosoftware.co.uk/wiki/index.php/JSnakeDevDiary |

That's lookin' reet smart - it's certainly nice and nippy! In fact, it's probably already faster than the devilishly-quick Hyper Viper! And again, just wanted to re-echo my thanks for continuing to maintain a dev diary!
