The 'to do' list is very small now.... Assigned some 'more realistic' high scores, and adjusted the bonus awarded at the end of each level, so you have some chance of the first digit in the score being used ! 😅 Leading zeroes have been ditched from the high score display.... Won't be long now....

'Search for the Lost Orb' is a text-based adventure game for the BBC Micro that I found whilst going through my disk collection. So far I have been unable to find out who actually wrote it. I asked the people on stardot, but had no luck. I think it could be Andy Bray (RIP) who I knew well BITD.

Just for fun this evening, played Mega-CD Soul Star. Kina funny playing one of my own games, but I was in the mood... Did make me think of doing a PC retro style version. Same graphics and sound, but running at a much higher frame rate, plus loads more fx sprites!😃 Hmm... Might do it just for fun.🙂

Wonderful game! planetasinclair.blogspot.com/2026/02/same...

The 6502 Opcode Periodic Table

Mini break over, back home now.... Just testing some stuff with a non-zero value in the clear screen procedure.... Highlighted a few issues, one with the DUCK sprite where I was wiping a bit too much than was necessary ! Pretty-much fixed, saved some more cycles !

So rolled back a week and did a preliminary run thru to level 12 - no bugs seen ! Now just need to compare all asm files and reintroduce changes I made in the last week until I (hopefully) notice something that will break stuff ! ....this may take a while ! 🙃

One of the things I wanted to do with my Commodore 64 Ultimate was use the Swiftlink MODEM emulation layer to write some games/BBS that used it. I put together a video about programming it in BASIC. Its a long at an hour :( Hope it helps someone though! #Commodore64 youtu.be/ORFUkjvXaMk?...

I am delighted to announce the release of my latest project: Fully documented source code for The Sentinel, Geoff Crammond’s 1986 masterpiece. Here’s the repository; deep dives coming soon. See thread for details. 1/9 github.com/markmoxon/th... #retrocomputing #retrogaming #bbcmicro #c64 #8bit

Curry with friends tonight when I realised.... Harry is 16 pixels high, that's 2 character rows, let's call them harry_head and harry_belly. I'm checking both for egg or grain collection. But grain ALWAYS sits on the floor, so I don't have to check his head for grain ! 🙄 Saves a bit of code ! 😅

I've just uploaded a fix a user reported soft crash to NEXXT studio (the tool i make nearly all my NES graphics in). we're now at 3.7.5 Grab the latest version here: frankengraphics.itch.io/nexxt

Random game of the night.... Nutcraka - Software Projects - BBC Micro Never heard of this until a few years ago.... Has some Frak! vibes. Loads of nice scenery, just could have done with a bit more squirrel animation. Mode 1 game and memory is limited, so the squirrel doing the jitterbug is fine!

Another attempt at a BBC Micro Mode 7 demo effect today - the Moiré pattern. Could do with some colour and further optimization, but just wanted to get the basic effect working. This demo is accompanied by some classic Mad Max {Jochen Hippel) music. 🔊 #bbcmicro #demoscene

Trying out some visualisation effects in the player, making better use of the space and moving the track metadata into the scroll text. Broken a few things along the way, but so far working okay even with the software bass active. Now to reduce the number of cycles it takes to display. 🔊

The last bug hunt - at the moment, that I'm aware of ! A weird feature in the level 'spiral introduction', where a goose/hen can be seen 'jumping'.... It's only when you slow down the display that you can see what's really going on... It doesn't help that the goose is 'changing direction' as well !

Well, I thought that'd take a lot longer than it did ! Bug be splatted ! 😊

Frak! - Level 4 onwards came to mind, where everything is upside down ! I started thinking how I would go about achieving this with Chuckulus, and gave myself a headache ! I was never seriously considering making it a feature anyway ! 😅🤯

The following algorithm written in #6502assembly checks whether ASCII character loaded in the 8-bit accumulator is a hexadecimal digit ('0'-'9', 'A'-'F'). In case it is a hexadecimal digit, the corresponding value from 0000 to 1111 is stored in the low nibble of the accumulator.

Ooh this is solid fun!

Now, re-enabled the X orbit for a full test..... A bit tricky in places, and there's a bit of PANIC there, but easy to evade the DUCK when you get the hang of it....... Plus I've build in options to speed up DUCK Y homing reaction / X orbit speed as difficulty progresses ! THIS WILL DO, ME ! 😲

#LogLoads64 Wolfling A recent conversation about whether I have or do not have (I do not) the "Reloaded" version of this for the #C64 has driven me to add it here. If you haven't played this - play it. Gorgeous animation, music, GFX, gameplay - it has it all. The SID as soon as you start, *mwah*!

Now that 2026 is underway, it's a good time to post an updated collage of my DOS games. Since I have nine out now, that fits into a nice neat rectangle. So here are all 9 #msdos games I released from 2020 to 2025. All #cga, all running on an #ibmpc, all available from cyningstan.itch.io

Today we have a classic scroller on the BBC Micro with a slight twist... custom font scaled dynamically to 16x16 pixels and continuous gradient applied to give the impression of more colours than supported by Mode 5. All software scrolling (no CRTC abuse) so works on the Acorn Electron too. 🔊

More 6845 CRTC experimentation on the BBC Micro. This time it's Mode 1 and an infinite vertical scroller. I'm probably not doing this right as it's not as smooth as I would expect. Need to do some more reading on this one. No music with this demo. #bbcmicro #demoscene

New version and demo recovered? planetasinclair.blogspot.com/2025/12/thom...

Ooh, found a new bug ! While on a ladder, Harry can jump straight up, fall off the bottom of the ladder and plummet to his death. That's fine, just a sprite bodge left on the screen as he does so. It's the only time Harry actually 'moves', I've forgotten to adjust part of the Harry plot proc !

So, having the control set option on the instructions page is fine, would help if I reflected the choice within the game scroller ! 😅 This was more of a pig, as a lot of the scroller text is pre-compressed, so couldn't patch it after loading. A lot of data rejigging, but it's all done ! 🙄
