In this video I look at #Commodore64 "Demon Blue", its use of bitmap mode mixed with characters, hires sprite overlay, dynamic sprites, and find its collision detection screen area. youtu.be/IwWvcKBa9BA

Spot the two super scaled sprites boards (different revisions) in this #MegaWang2000TurboEdition stack...

#MegaWang2000TurboEdition with all video and audio boards plugged in is now at 80 watts. I think it's about time to split the power delivery to the backplane.

This video shows how to setup the programmer tool, and use it to erase/write/read a 2 megabyte #Commodore64 cartridge. youtu.be/GBg5k46B5Pw

I take a look at #Commodore64 "Arctic Shipwreck". Published by Commodore in 1983, developed by F°451 Software with music by Marton Saghegyi. It has a really nice iceberg draw, an early example of a sprite sheet, and you play a mammoth! youtu.be/dGgzhgPe5wE

A new 2 megabyte #Commodore64 flash cartridge and a Raspberry Pi hat programming tool, with software running on the Raspberry Pi that can erase, write, and read the cartridge flash memory. #OpenSource youtu.be/As3GDnLnZ3U

I'm getting old. I just mistook my Windows shell for my RaspberryPi5 shell.

I look at #Commodore64 "Grand Prix Circuit" published in 1989 by Accolade, it has music with samples, uses hires and multicolour bitmap modes, scanline track drawing, and dynamic sprites. youtu.be/zPpYLIjdq14

I am once again reminded of how much I dislike Visual Studio 2017 project property sheets (props files), but also understand the problem they're trying to fix.

A quick "After Burner" palette fade and raster interrupt test for my #Commodore64 #MegaWang2000TurboEdition hardware. youtu.be/nWQjSncJ57M

How does this "X-File" demo display 11 "sprites" in a horizontal band on a #Commodore64 which normally has a limit of 8 sprites in a horizontal band? Let's dig into the CPU cycles to see what it's doing. youtu.be/GEVu3zEhoic

Next video is going to be delayed until I recover from this C-lurgy. I have no voice and cannot see straight.

Especially for @fuzzweed.co.uk yes the compression tool works with #Commodore TED machines, like the Plus/4 and C16. ( martinpiper.github.io/C64WasmCompr... )

Almost at 7K :) www.youtube.com/@MartinPiper...

Because I'm crazy, I've created an online WebAssembly version of my #Commodore64 compression tool. As usual source code is included. :) martinpiper.github.io/C64WasmCompr...

In this video I look at #Commodore64 "Defender", the Atarisoft version. An early efficient sprite multiplexor, finding the mountains data, comparison to arcade hardware, and dynamic characters used for the player bullets/lasers. youtu.be/hj7dk1BbPi4

This video shows the "After Burner" demo for #Commodore64 and my #MegaWang2000TurboEdition hardware. The game is pretty much complete now and is included in SDK V1.0.0.9. This is part of my expansion video and audio hardware using 74LS TTL electronics. youtu.be/iQVu70-Ao1g

In this video I take a look at #Commodore64 "H.E.R.O." from 1984. I look at how extended colour mode is used, which is quite unusual to see in a game. youtu.be/db7d_q9pVFY

The After Burner arcade attract mode would pause the demo game play and effortlessly scroll the high score table up the screen using some of its 17 tile screens! For my #MegaWang2000TurboEdition hardware it's using one tile screen and raster splits.

When you can't quite remember where you put your Visual Studio 2012 installer... dir *vs2012*.iso *vs2012*.exe *vs2012*.msi *vs2012*.nrg *visual*studio*2012*.iso *visual*studio*2012*.exe *visual*studio*2012*.msi *visual*studio*2012*.nrg *vc2012*.iso *vc2012*.exe *vc2012*.msi *vc2012*.nrg /s /b

I had one of these BigTrak way way way back in the day, with its transport trailer. www.robotroom.com/BigTrak.html I seem to remember a magazine or book series that described a complicated electronics project to add on to the BigTrak and make it computer controlled? Does anyone know which book/mag?

#Electronics geeks. Instead of this 44 position standard 100 thou card edge connector, is there a ZIF version of this? So I can quickly insert and remove cards?

Anyone want 8MB of #Commodore64 flash cartridge?

Added the mission complete pictures and also the animated hand in the attract mode. The original arcade has 17 tile screens for these extra graphics, this current #MegaWang2000TurboEdition setup only has two tiles layers. So the hand is using sprites.

Testing code on a real #Commodore64 and I keep on wanting to press Alt+W to enable turbo execution mode... (Vice emulator default turbo key combination.)

Quintuplets!

I take a look at #Commodore64 "Lode Runner" from 1983.The BASIC disk loader with code, bitmap game display, nice circular dissolve, dynamic hires hardware sprites with decompression/conversion, and find some old bitmap pixel plot reveal code? youtu.be/5ifs6mro3Xk

Extra sound effects and score hits bonus calculation, rewards the player when they clear more enemies in a stage, and also helps use what's left of the main RAM... Coding this is fun. :)

#cat says I am overseer of all that I gaze upon.

#C64 2MB flash cart dev...

Me, when I look at some old code and wonder how it ever worked...

In this video I take a look at #Commodore64 "Strangeloop". A game from very early in the C64 history, which uses dynamic chars and a nice scrolling message, quite a lot of detailed sprites, unusual map draw, and I create a compressed version. youtu.be/fYrhv-YNNWE

Finalising #C64 Audio2 expansion hardware specs, mostly the amount of memory for extra music... #VolumeUp I plan to sell this #MegaWang2000TurboEdition expansion soon, which will be available as separate audio, video, memory expansion boards.

This video shows some of the updates to the "After Burner" demo for #Commodore64. The landscape now has more graphics with hills and rivers, enemy attacks waves now include rolls and can also attack from behind. I plan to sell this #MegaWang2000TurboEdition expansion soon. youtu.be/XWX8UqmuRmM

#PSA Do not buy these peanut chocolate things. After opening the packet, or sometimes even with the unopened packet safely in storage, the items will spontaneously dissappear without warning.

After quite a bit of data generation optimisation, I've gone from 637 bytes to 7302 bytes free in #Commodore64 main memory, so I can start adding extra enemy types and background graphics again. The #MegaWang2000TurboEdition hardware has much more free memory.

A quick little bonus video where I take a look at Commodore 64 "Morphing Starball". A very nice one file demo using one sprite to display a screen full of coloured pixels. youtu.be/m_HA1P-FFgE

In this video I take a look at #Commodore64 "Smash T.V.". The very nice intro sequence, large sprite sheet scroller, large sprite logo, bitmap software sprites, and an efficient early update multiplexor. youtu.be/d2nj5DZPGyc

Oh #cat I have work to do...

In this video I take a look at #Commodore64 "Speedball 2". The nice animated intro, game bitmap and text screens usage, just in time multiplexor, and delta decompression. youtu.be/bbFKD34cG6U

Testing the mission complete code path... In the original arcade this text is one big sprite. The ending pictures will probably be squeezed into the front tile screen.

Now 854 bytes free after adding the radar...

#Commodore64 geeks, would chamfered corners on a cartridge edge connector be better or worse?

One of us always lies, and the other one always tells the truth. #CaturdayEve

After adding all the status and speed display animations I've got 1249 bytes free in #Commodore64 main memory. Will I be able to squeeze in the radar in the top right? This #MegaWang2000TurboEdition hardware will be available to buy soon(ish).

I look at the "Fanta in Space" #Commodore64 demo from 2008 which includes, four sample channels + filter!, two SID channels, triangle test frequency as volume, NMI Stable CIA modified JMP, two sample buffers, mainline mixing. youtu.be/D2lEVw7fsMY
