A technical look at this #Commodore64 demo "Viva Las Vegas" with a deeper dive for the parts that use fast bitmap scrolling with animation. How do these parts apparently move so much around on screen? They don't, it's all smoke and mirrors. youtu.be/mRNjCUO2mZs

A deeper technical dive for the circle scroll part in the #Commodore64 demo "Viva Las Vegas". It uses two bitmaps, with extra colour fetches, using a timed stabalised NMI with auto ACK, and has background colour updates timed with the raster beam. youtu.be/KjuSMGK8TJU

This #Comodore64 cartridge programming tool can erase, write, and read cartridge flash memory as well as serial EEPROM. I erase and program two gmod2, two megabyter, and five C64MegaCart, all in under two minutes. :) www.youtube.com/watch?v=zm2W...

I look at #Commodore64 game "Championship Jetski Simulator", specifically the water particle plotter. This is my **300th Commodore 64 related video** When I started these videos I didn't imagine there would be so many! youtu.be/OYvu0lIxYPY

The full MegaWang board stack plugged into my #Commodore64. The Advanced Processing Unit (APU) board has been updated to expand the instruction memory, fix some memory corruption, update the design to SMT components from through hole, and remove the bodge wires. youtu.be/7MHpxAZKzug

I look at Amiga "Aonic" coded by @reassembler . How does this game have such colourful parallax? Well it has full screen sprites, uses a dynamic copper, and a blitter object cache! youtu.be/AUWzArV-YUM

I did add Python to acme a while ago. This could be used for more complex data processing with the source code... But the convtab is much easier for simple character encoding. github.com/martinpiper/...

Probably the easiest way is to use a convtab with file option, the file defines the appropriate character conversion. github.com/martinpiper/...

I look at #Commodore64 game "Katakis" briefly released in 1998 by Rainbow Arts. Let's look at all the bosses, parallax scrolling, and debug the disk protection check. Does it really one screen buffer? youtu.be/iXGGh3EgKeQ

I cannot wait until April 1st to post this... This is obviously not real... But a MegaWangPhone (to beat the CommodorePhone) is an interesting idea....

The last #MegaWang board to upgrade to surface mount is the Advanced Processing Unit. Like the #Amiga copper chip it can time updates to the raster position. This can access the whole hardware memory and perform calculations however.
