The same functionality, a scrolling character screen layer. But one using through hole, the other using surface mount.

I look at #Commodore64 "The Sentinel", published in 1986 by Firebird, created by Geoffrey Crammond (of course). The game uses an interesting "not bitmap" mode to render, with multiple charset based scrolling, and what looks like a lot of maths and ray casting.

This video shows the Audio2 layer working with the #Commodore64 and additional #MegaWang2000TurboEdition hardware. This has 2MB memory per channel with stereo output up to 78KHz 8-bit sample rate with volume control.

I look at #Commodore64 "Dropzone", published in 1984 by US gold. Nice dynamic charset for the title logo, hardware and software sprites, several charsets for the landscape, sprites and chars for the score, and memory patterns for game objects.

This video shows the bitmap RGB 565 layer working with the #Commodore64 and additional hardware. I'm working on finalising the manufacturing design for the remaining boards. Thank you @pcbwayofficial.bsky.social @queenelaine.bsky.social for working boards.

I look at #Commodore64 "Stunt Car Racer". Published in 1989 by MicroStyle, coded by Geoffrey Crammond. Using double buffered bitmaps, nice use of sprites, bitmap clear and engine draw, with a delta colour update, 3D Line draw, and a tweak to render more track!

Just wanted to share this super cool tech showpiece from @rovertronic.com over on Twitter
Demonstrating a cool new technique in Super Mario 64 to make portals just like you'd see in, well "Portal"
It looks kinda surreal but it's a super impressive visual effect!

I look at #Commodore64 "Super Mario Bros 64" by ZeroPaige in 2019. How the screen scroll uses VSP, the Mario sprite split render, some dynamic sprites, and find some original (mostly) NES code.

My #cat is blocking my keyboard,
What on earth shall I do?
Her fur is covering my mouse pad,
The pointer no longer moves.
My cat meows at the screen,
The meeting can only hear her.
My cat is being my cat,
I think she thinks she owns me.

I take a short trip down memory lane for #Commodore64 "Green Beret", published in 1986 by Imagine. The old memories of the Ocean/Imagine loader, and the sprite limit handling when the special weapon is used.

MegaWang’s turbo retro encabulator now basically has several new principles involved. Instead of power being generated by the relative motion of conductors and fluxes, it's produced by the modal interaction of magneto reluctance and capacitive duractance.

Today on my mysterious #Windows box I was just checking if I had openssl installed somewhere with a quick "where openssl" and it was in the C:\Strawberry directory. I really do not remember installing Strawberry Perl, but I must have done at some point.

Because I had 53 bytes free, I thought I would add the "your plane has been winged before exploding into a ball of flames" code. I now have 2 bytes free.

#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.
