Testing new audio hardware designs for my #MegaWang2000TurboEdition #Commodore64 "After Burner" conversion. Volume up for the take-off sequence. I think it makes a special difference, but that's because I have very old memories of pumping coins into this arcade machine.

In this video I run through the updates to the "After Burner" demo for #Commodore64. This is part of my #MegaWang2000TurboEdition expansion video and audio hardware using 74LS TTL electronics.

#MegaWang2000TurboEdition hardware. The power of one extra AND gate. This takes an existing signal for "Y position is off the screen" and sends it to the "pixel row completed" signal. This gives a very cheap and effective clip test that prioritises on-screen pixel plotting, more sprites basically.

In this video I test the new bug fixed "super scaled sprites" #MegaWang2000TurboEdition PCB with an updated "After Burner" demo for #Commodore64. This is part of my expansion video and audio hardware using 74LS TTL electronics.

#Commodore64 #MegaWang2000TurboEdition hardware "After Burner" demo now includes the "canyon" sequence which reuses some of the landing sequence code. Interestingly the original arcade canyon sequence does not rotate and that's probably due to the huge sprites used.

#Commodore64 #MegaWang2000TurboEdition hardware "After Burner" demo now includes the "canyon" sequence which reuses some of the landing sequence code. Interestingly the original arcade canyon sequence does not rotate and that's probably due to the huge sprites used.

To increase the colours available, the palette banks are now dynamic during the titles and game. The landing sequence objects switch palette banks and then the buildings after that use another palette bank. #Commodore64 #MegaWang2000TurboEdition hardware "After Burner" demo.

Added a runway for the landing and takeoff refueling sequence to my #MegaWang2000TurboEdition hardware "After Burner" demo. This uses the APU "copper" board and the tiles layer containing a "road" with perspective.

I've found some hardware optimisations that should give me 15% more sprite draw time for my "After Burner" demo for #Commodore64 and my #MegaWang2000TurboEdition hardware. While PCBWay builds the update, I've been adding some extra landing and takeoff tests and extra graphics.

My "After Burner II" demo running on a real #Commodore64 with hundreds of scaled sprites, sampled audio, RGB565 colour, and higher resolution. Using my #MegaWang2000TurboEdition hardware. Thanks to @PCBWay for a build that worked first time.

#MegaWang2000TurboEdition quick visual update about the new super scaled sprites PCB for the #Commodore64 ... Video later...

Checking orientation and part numbers, all looks good... #MegaWang2000TurboEdition super scaled sprites is almost done!

I think this is the final #MegaWang2000TurboEdition board design for super scaled sprites. Weighing in at 245mm x 218mm. Signal separation pathways split the board into quadrants between the major parts of the logic, the sprite RAM and register RAM, calculation, and pixel outputs.

#MegaWang2000TurboEdition hardware update, today I've been adding player missiles to test my #Commodore64 CPU time. Also the hardware has gained extra pixel and sprite offscreen checks, that optimise fill rate for sprites on screen. It looks like the first hardware will run reliably at 12.096 MHz.

#MegaWang2000TurboEdition hardware update, today I've been in software mode, adding some extra polish to the title screen sequence, the carrier take-off, and improving the enemy entity system. #FridayWang

#MegaWang2000TurboEdition hardware simulation and debugging of the super scaled sprites layer is complete. Accurate hardware simulation like this is slow but very necessary for debugging #electronics. Next step, get this built and plug it into my #Commodore64 :)

In this video I use the After Burner demo to test the new super scaled sprites functionality for my #MegaWang2000TurboEdition hardware and Commodore 64. This expands upon the old scaled sprites board by using the entire frame buffer time to render and adds sprite width and height options.

In this video I cover plans for a new #MegaWang2000TurboEdition board to provide super scaled sprites functionality for the #Commodore64. This expands upon the existing scaled sprites board by using the entire frame buffer time to render instead of just scanline rendering and expanding sprite width and height options.

Update for #MegaWang2000TurboEdition hardware for #Commodore64 design tests. Today I've been adding logic. Three scaled sprites, test pattern. Java emulation output on the left, hardware digital simulation on the right (zoomed in a bit). Pixels and colours match.

Update for #MegaWang2000TurboEdition hardware for #Commodore64 design tests. Today I'm in super scaled sprite hardware design mode. Using Proteus schematic capture with 74LS TTL logic and some CMOS static RAM. This is a portion of the design...
