A little more progress... the music is in, added some trees (which randomly disappear at the moment, and don't look right above the horizon due to the palette change) and a mountain range. The small map (you might recognise it) will eventually mirror the curves on screen, but not quite working yet🔊

A quick palette change at the top half of the screen (leaves no longer changing colour at the horizon), and a fix to the disappearing trees, along with better tracking of road curvature and height. Next to see if I can add opponents to the track without severely impacting performance. 🔊

OK, back to the bottom of the screen and giving the little robot a little more wiggle room (16 char rows instead of 12). However, this version takes more time and space. I also need to check if this is stable on a real Electron. Did I say I thrive on self-imposed constraints? 😂

Just a small update, but I now have 4x speed SID files dynamically playing on the SN76489. Cycles are very tight so I had to disable the scope and colour cycling, but sounds good. 🔊

Added in IRQ software bass by default... this is less harsh than using periodic noise via the LFSR. Also improved the scope visualization a little. Still lots of issues with SID files that trample all over the BBC Micro memory map, but this one appears to work just fine. 🔊

"Wanted: Monty Mole" (WIP) on Acorn Electron. Took longer than expected because movement code is quite convoluted. Not perfect yet. Slowed down to target 25fps. Funny quirks in original game (and in mine): 1. No eye when walking right, 2. Walks slower on some tiles because constantly "falling"

Inspired by @kieranhj.bsky.social 's realtime AKS player on the BBC Micro, I reused the AY-3-8912 to SN76489 converter to expand this to realtime playback of PT3 files from Vortex Tracker. This opens up another tracker that can now be used for BBC Micro music composition. Much smaller than ym files.

I'm spending time on trying to get a working layout for the game because contrary to the Atari ST that has more of wider resolution (320x200) the Oric is more square (240x224) so we have more vertical space. So I decided to try to have the portraits always visible!

Exploiting RAM contention to sync to hblank after RTC interrupt fires to get stable horizontal colour palette switching in MODE1 on Acorn Electron (from SWRAM). Video reveals the exact locations of the palette switches, including partial colour changes. Bit afraid to test on real hardware 🫣

More Electron coding, and this time we get going with Modes and Colours, looking at the 6 screen modes available on the Elk. Also look at some commands that help with coding too. Ooh… 😮

#C64 #Delphian progress: life's been a bit up and down recently, but it's okay now. So, did a bit more work on the game, getting the star chart to work. I can now select a destination star system (that's in range) and jump there. Still some optimisation to do, but here's how it's looking so far...

SoftSID 0.0.6 for the BBC Micro Added ability to specify the .sid file and track number on the command line. Many optimizations to bring the cycle count down too. Should be ready for a preview release soon once I've chased a few more cycles and relocated some more example SIDs. 🔊
